Web · Discrete bladder mass and nodule are findings of bladder TCCs. This lesion shows early enhancement after contrast injection (within 60 s) when the lesion is surrounded by low-attenuated urine. However, filling defect in delayed-phase image is also helpful in the detection of tumor when the nodule is large (Fig. c). O que é redação descritiva?
However, there is one exception. Usually tumours that do not invade the basement membrane as described as benign, and thus not included in the TNM system. They are classed as Ta as opposed to T1-T4 tumours. Pelvic and ureteric tumours — are treated by nephroureterectomy. Radio and chemotherapies have been shown to be of little value. Bladder tumours — treatment for these depends on the stage described above :.
Sagittal images are useful in detecting lesions in the anterior and posterior wall [ 13 ]. Recently, 3D sequence MR imaging is feasible. Compared to 2D sequence, 3D sequence offers shorter acquisition time, volumetric coverage without interslice gaps, and higher signal-to-noise ratio [ 19 ]. With this technique, single-breath-hold imaging acquisition is possible. The bladder wall does not show early enhancement on the gadolinium-enhanced images. In the early phase 20 s after intravenous contrast injection , bladder TCCs show more enhancement than adjacent bladder muscle [ 23 ]. The bladder TCCs, mucosal, and submucosa have early enhancement, but bladder muscle shows late enhancement 60 s [ 18 ]. The bladder TCCs with increased cellular density show increased signal intensity on diffusion-weighted images and reduced signal intensity on apparent diffusion coefficient ADC maps [ 24 ].
Changes of signal intensity on diffusion-weighted images are more useful than ADC measurement, because there can be interobserver variation in ADC values in the bladder tumor in relatively thin bladder wall [ 25 ]. Diffusion-weighted image in bladder TCCs has shown improved differentiation of bladder TCCs from bladder muscle layer [ 26 — 29 ]. The clinical staging, with using CT or MR imaging, often underestimates tumor extent. CT is standard imaging modality for preoperative staging. However, perivesical edema or inflammation especially after bladder cancer treatment can mimic perivesical tumor spread. The TNM classification of the renal pelvis and ureter is tabulated in Table 2.
Table 2. Smoking, chemical carcinogens aniline, benzidine, aromatic amine, azo dyes , analgesic abuse, cyclophosphamide, and heavy caffeine consumption increased risk of TCCs [ 38 , 40 ]. Low-grade tumors have superficial, papillary appearance with broad base, are usually small and slowly growing, and have good prognosis [ 42 ]. High-grade tumors are less common, pedunculated or diffusely infiltrating, and more aggressive [ 43 ]. The TCCs from the upper urinary tracts are well visualized. These filling defects can be single or multiple and smooth, irregular, or stippled Fig.
Contrast material dispersed in the papillary mass is shown as stippled appearance in IVU. This finding also can be seen in benign lesions such as blood clot and fungus ball. Some TCCs can show stricture-like lesions; these findings can be misinterpreted as renal tuberculosis [ 40 ]. When tumors obstruct renal infundibulum, affected calyx is not visualized in IVU and this is calyceal amputation.
Note the surface of the lesion has mottled and streaky appearances suggesting papillary nature of the lesion stipple sign. Note adjacent hydronephrosis. Upper polar calyx is not seen in IVU due to obstruction of infundibulum phantom calyx TCCs from the ureter are seen as single or multiple filling defects. Stippling or proximal obstruction can be seen. When there are long-standing obstructions due to ureteric tumor, contrast excretion can be poor, and it may be hard to evaluate ureteric lesion.
When this happens, contrast-enhanced CT or retrograde pyelography RGP can be done for further evaluation. Retrograde pyelography is performed during cystoscopy, for further evaluation when upper urinary tract lesions are not well visualized during IVU or when patients are allergic to contrast materials. Amputated calyx can be seen when TCCs invade and obstruct renal infundibulum. Circumferential or eccentric ureteric strictures can be seen in TCC and sometimes they can be confused with benign strictures. In malignant stricture, there are usually ureteric fixation and nontapering margin [ 37 ]. RGP shows a filling defect in the left midureter.
With CT urography, a small renal pelvis mass and urinary tract mass can be detected. CT urography is superior to IVU in that urothelium, renal parenchyma, and adjacent tissue can be evaluated at a time. There have been multiple different CT urography protocols: single-bolus technique, split-bolus technique, and triple-bolus technique. Among them single-bolus technique is most commonly used in practice. In single-bolus technique, precontrast scan is acquired from kidney to symphysis pubis.
After that one bolus of contrast is injected and early, parenchymal, and excretory phase scan is acquired [ 46 ]. The advantage of this technique over the other technique split-bolus and triple-bolus technique is that it can provide optimal opacification and distension of the renal pelvis and ureter. In addition, small renal cell carcinomas can be more easily detected compared with other technique. The major disadvantage of this technique is increased radiation dose due to multiple imaging phases. In split-bolus technique, contrast injection is divided into two sessions and imaging is acquired in combined nephrogenic and excretory phase. The advantage of this technique is decreased radiation due to reduced imaging phase [ 47 , 48 ]. However, there are some questions about the optimal opacification of distal ureter due to half dose of contrast for excreted contrast [ 47 , 48 ].
Triple-bolus technique splits dose of contrast into three boluses and acquires combined early-nephrogenic phase [ 49 ]. With this technique, the radiation dose can be reduced, but the opacification and distension of ureter are also questionable in this technique. In addition, detectability of small renal lesion such as small renal cell carcinoma can be decreased. In performing CT urography, ancillary techniques, such as abdominal compression, intravenous IV saline, IV furosemide, and prone positioning, should be considered [ 46 ]. Abdominal compression is done for opacification of proximal urinary tract. But, the usefulness is in doubt [ 50 ]. IV saline injection is suggested in some studies to distend distal ureters [ 50 ]. IV diuretic injection improves distension and opacification of ureter [ 5 ].
But there are some difficulties in IV injection of diuretics in daily practice, because of allergy or hypotension. Single-bolus technique is most commonly used because of optimal distension of the ureter and higher sensitivity in the detection of renal mass [ 46 ]. To decrease beam-hardening artifact, which can interfere detection of small lesions, delayed images after 5 min are recommended [ 51 ].
When there is obstruction, more delayed image acquisition for excretory phase is needed. Renal TCCs are seen as filling defect renal pelvis wall thickening in the excretory phase Fig. Other findings are pelvicalyceal irregularity, oncocalyx, or obstructed calyx Fig. Early TCCs are separated from renal parenchyma. Advanced TCCs extend to renal parenchyma. Imaging features for renal TCCs are as follows: mass epicenter in the renal pelvis or calyx, presence of focal filling defect in collecting system, reniform contour preservation, mainly solid feature, homogeneous attenuation, moderate enhancement, and extension of tumor to ureteropelvic junction.
Contrast-enhanced CT shows extensive parenchymal invasion arrows of the left kidney. Note, the left kidney conserves reniform contour and mass shows homogeneous and solid feature Ureteral thickening is the most common manifestation of ureteral TCCs Fig. To detect thickening of ureter in ureter TCCs, meticulous check of all three phase is needed because subtle urothelial thickening can be seen in all three phases.
Not only irregular and eccentric but also circumferential and smooth wall thickening can be seen in ureteral TCCs [ 52 ]. Enhancement pattern is usually focal and eccentric. Care should be taken for evaluation of ureteral enhancement because this can also be seen in inflammatory lesions [ 53 ]. Calcification can be seen ureteral TCCS. Calcification is usually located eccentrically or in the wall. This should be differentiated urinary stone which is located in the central lumen of ureter. Periureteral fat stranding can be seen in urinary TCCs. Usually cancer-related periureteral fat stranding is persistent after treatment; this is differential point from inflammation-related periureteral fat stranding. Filling defects are findings of ureteral TCCs.
But, when mass size is small, sometimes it is difficult to detect tumor in excretory phase due to beam-hardening artifact. Some of these lesions can be seen in the early or nephrogenic phase [ 54 ]. Ureteral TCCs can accompany hydronephrosis or hydroureter. Dilatation of proximal ureter can be seen even when ureteral TCCs are no visible. So when there is ureteral dilatation proximal to suspected stricture without definite mass, ureteroscopic examination should be done not to miss small ureteral TCCs [ 52 ]. Coronal reformation image of contrast-enhanced CT shows irregular wall thickening of the right midureter arrows Fig. Contrast-enhanced CT shows an enhancing soft tissue lesion arrow in the right distal ureter.
Note non-opacification of both external iliac veins, indicating that this image is early phase after contrast injection 2. Generally, MR imaging is less commonly used compared with CT urography due to more time for acquiring image and more motion-related artifacts. MR imaging has high soft tissue contrast, is independent to renal function, and allows multiplanar imaging. TCC shows lower-signal intensity than urine in T2-weighted images and tumors are well visualized. In gadolinium contrast-enhanced images, TCCs show moderate enhancement Fig. MR urography is used in the evaluation of the upper urinary tract. Usually ureter stone has sharp margin but ureter TCCs usually have irregular margins. Mass is confined to the renal pelvis. Symptoms are gross hematuria and irritation during voiding.
Risk factors are nonbilharzial region residency, cyclophosphamide, intravesical BCG, smoking, bladder stone, or chronic infection. Paraplegic patients usually have both bladder stone and infection [ 1 , 56 ]. Tumors are high grade and locally aggressive with muscle invasion [ 57 ]. They usually occur at the trigone and bladder lateral wall and diverticula [ 58 ]. Prognosis is generally poor because it presents with advanced stage. Bladder squamous cell carcinoma has nonspecific imaging findings. Tumors show focal or diffuse bladder wall thickening or single enhancing bladder mass Fig.
Diverticular squamous cell carcinomas are soft tissue masses and occasionally surface calcification may coexist [ 58 ]. Bladder squamous cell carcinoma shows sessile growth pattern compared to papillary growth pattern of TCCs. Bladder wall thickening or calcification can be seen. Contrast-enhanced CT shows diffuse bladder wall thickening with mass formation in the posterior wall of the bladder asterisk. Note perivesical infiltration arrows , which was histologically confirmed to tumor spread 2. It can be classified as primary nonurachal and urachal and secondary. The mean age of diagnosis is 60 years, and urachal cancer occurs 10 years earlier. Nonurachal adenocarcinoma has male predominance, but urachal adenocarcinoma has equal prevalence in men and women.
Hematuria and irritation are common symptoms. Umbilical discharge can be seen in urachal cancer. Bladder adenocarcinoma is associated with bladder exstrophy and persistent urachus. Other risk factors are chronic mucosal irritation associated with intestinal metaplasia, urinary diversion, and pelvic lipomatosis associated with cystitis glandularis. Metastatic adenocarcinoma of the bladder is more common than primary bladder adenocarcinoma.
Adenocarcinoma is most common histologic type of secondary bladder neoplasms. Primary sites include direct invasion from colon, prostate, rectum, and pelvic tumors [ 63 ]. Hematogenous metastases from the stomach, breast, and lung are less common. Differentiation of primary and secondary bladder adenocarcinomas is important in deciding treatment plan. When bladder metastases occur, usually there are locally invasive primary malignancies. Although urine cytology is useful, sensitivity is limited when tumor is located beneath mucosal layer. Primary adenocarcinoma is histologically same with colon adenocarcinoma, and it is difficult to distinguish primary adenocarcinoma from metastatic adenocarcinoma, even with special stain [ 63 ]. Urachus is a midline remnant of the cloaca and allantois.
It is located extraperitoneally and is bounded by the transverse fascia and parietal peritoneum. In fetal life, urachus is regressed to a fibrous band and becomes medial umbilical ligament. This extend anterior dome of the bladder to umbilicus. Incomplete regression of the urachus causes four anomalies: urachal sinus, patent urachus, urachal diverticulum, and urachal cyst. Because urachal remnant is lined by transitional epithelium, the suggested pathogenesis is metaplasia of urachal mucosa into columnar epithelium and malignant transformation [ 65 ]. In urachal cancer, mucin stain is positive [ 62 ].
Urachal cancer has male predominance and occurs between 40 and 79 years old [ 65 , 67 ]. Common symptoms are hematuria, dysuria, abdominal pain, suprapubic mass, and discharge from the umbilicus [ 17 , 68 ]. In IVU or cystography, urachal adenocarcinoma is seen as a filling defect or extrinsic compression in the dome of the bladder. Tumor can be detected with ultrasound US as a fluid-filled, mixed echogenic solid mass with or without calcification adjacent to abdominal wall. But these imaging findings are nonspecific.
CT and MR imaging are more accurate imaging modalities for evaluation of both local staging and distant metastases. CT feature is a midline mass anterior superior to the dome of the bladder with mixed solid and cystic appearance Fig. The cystic component is mucin. In contrast to bladder TCCs, extravesical tumor spread is common Fig. Pseudomyxoma peritonei rarely occurs. Contrast-enhanced CT shows well-enhancing mass arrow in the anterior wall of the bladder.
There are irregularities in the outer margin of the tumor indicating perivesical tumor extension Fig. Contrast-enhanced CT scan shows a mixed cystic and solid midline mass with punctate calcification anterocranial to the bladder arrows MR imaging is the best technique for evaluation of urachal adenocarcinoma. On T2-weighted images, there are focal high-signal-intensity lesions suggestive of mucin [ 65 ].
