Carcinoma of urachus with extensive abdominal calcification.
Carcinoma of the urachus, a relatively rare genitourinary neoplasm, usually presents as a supravesical mass. This tumor may occasionally calcify, which together with other radiographic and clinical features may permit a specific preoperative diagnosis. The calcifications also enable an evaluation of recurrence via plain films. A case is presented, with the clinical, radiologic, sonographic, and radionuclide imaging characteristics reviewed.
