It may: But a contrast enhanced study would be more sensitive. If concerned, see a urologist for full evaluation and diagnostic work-up. Best wishes.

Occassionally: A large ulcerating cancer perforating thru muscularis will show up. A small superficial lesion of mucosa can only de defined on cytoscopy. This is the type of lesion that after biopsy can be treated by intra bladder bcg.

Yes: Most commonly are tumors from the gastrointestinal tract. Stomach, small intestine, appendix, colon. Can occur in the lungs too. Most of the times are asymptomatic until they are advance and cause carcinoid syndrome(tachycardia, flushing, tremors, high blood pressure, sweating episodes, diarrhea) commonly metastasize to the liver.

What kind of tumors would a cranial CT scan not show? Why would they not show up?

It's possible: Ct scans are a great first step in evaluating the brain. However, they are not infallible. All tumors start as small lesions and can be missed at a very small size on ct scans. Often, a ct scan will show the brain's reaction to a tumor rather than the tumor itself. If there is little or no reaction, the tumor can be even harder to detect.

Depends.: For kidney stones we use no contrast, but we don't get as good a look at the solid organs. Contrast is usually helpful, but not always necessary.

There is: no difference in the performance of the CT scan itself, except that the scan with contrast requires an intravenous injection of contrast material.
