Computed tomography is an extremely accurate method of obtaining more definitive diagnostic information about a renal mass discovered on a urogram. Benign renal cysts are readily distinguished from solid renal neoplasms, and CT is often valuable in characterizing possible juxtarenal masses. The cause of a nonfunctioning kidney(s) on a urogram can often be discerned, and hydronephrosis is easily detected.
The radiographic, colonoscopic, and pathologic findings in this case of Behcet's colitis differ completely from ulcerative or granulomatous colitis as well as from other, less commonly seen inflammatory colitides. Discrete, peptic-type ulcers, with normal intervening mucosa and normal overall configuration of the colon, are seen on radiography and endoscopy. The angiographic features are not diagnostic but differ considerably from findings in other inflammatory colitides. No tortuous arterioles, mucosal hyperemia or early venous filling was encountered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
