Most of the CT manifestations of bladder cancer are single, papillary or cauliflower-like, thickening of the bladder wall, may invade neighboring organs, and more than moderate enhancement.
CT is valuable in diagnosing bladder tumors and assessing the extent of bladder cancer infiltration (especially showing extravesical tumor infiltration). If cystoscopy reveals that the tumor is broad-based and non-terminal, with high malignancy and the possibility of muscle layer infiltration, CT examination is feasible to understand the infiltration range of the tumor. The common CT manifestations are as follows:
CT scan shows that the bladder wall is thickened to different degrees, cauliflower-like, papillary, irregular, the density of the mass is not uniform, the surface is smooth and protrudes into the cavity, and it is slightly hairy when it invades the outer wall, sandy calcification or necrosis can be seen in larger masses, and the blood clot in the bladder can change with the position.
When metastatic foci appear, patients will have the symptom of enlarged pelvic or retroperitoneal lymph nodes, and the indicator of its lymph node metastasis is its diameter is larger than 1.5cm.
CT examination can only indicate the presence of occupying lesions, and cannot diagnose whether it is bladder cancer or not, if there is any abnormality, cystoscopic tissue biopsy should be carried out to confirm the diagnosis.
If bladder cancer is suspected or diagnosed, it is recommended to go to regular hospitals for comprehensive assessment of the condition, follow the doctor’s instructions and choose the appropriate treatment plan to avoid delaying the condition.
