Overview
CT Scan
Abdominal and pelvic CT scans are helpful in the diagnosis of transitional cell carcinoma.
Transitional cell carcinoma of bladder
- Transitional cell carcinoma of bladder appear as either focal regions of thickening of the bladder wall, or as masses protruding into the bladder lumen, or in advanced cases, extending into adjacent tissues.
- Care should be taken in assessing bladder wall thickness as this changes with the degree of bladder distension and varies from patient to patient, e.g. patients with bladder outlet obstruction due to benign prostatic hypertrophy. In general, however, asymmetric mural thickening should be viewed with suspicion.
- The masses are of soft tissue attenuation and may be encrusted with small calcifications.
- Although unable to distinguish between T1, T2 and T3a (microscopic extravesical spread), CT is able to distinguish T3b tumors (stranding/nodules in perivesical fat) and T4 tumors (direct extension into adjacent structures/loss of normal fat plane).
- Care should be exercised when interpreting stranding or nodularity following transurethral resection or even biopsy, as these changes may be postoperative.
