 Edited by ScholarGen MediAI Editorial Team A 5-cm Pancreatic Cystic Mass Discovered During CT Pulmonary Angiography Executive Clinical Summary A man in his 50s underwent CT pulmonary angiography (CTPA) because of exertional dyspnea and palpitations. Pulmonary embolism was not identified, but an unexpected cystic mass was detected in the pancreatic tail. Dedicated pancreatic CT demonstrated an approximately 4.4 × 3.8 × 5.0 cm lobulated complex cystic lesion with an enhancing mural solid component. The main pancreatic duct was not clearly connected to the lesion. CA 19-9 was elevated to 90.0 kU/L, while CEA, AFP, and CA 15-3 were reported as normal. These findings created a clinically important diagnostic problem. A large complex pancreatic cystic lesion with an enhancing solid component and elevated CA 19-9 cannot simply be labeled a benign incidental cyst. Branch-duct IPMN, cystic pancreatic neuroendocrine tumor, mucinous cystic neoplasm, and other cystic pancreatic lesions had to...

Congenital Unilateral Renal-Seminal Vesicle Agenesis: CT Urography Clues in a Man With Gross Hematuria

 Edited by ScholarGen MediAI Team When One Kidney Is Missing, Look Beyond the Kidney Executive Clinical Summary A man in his early 60s underwent CT urography for gross hematuria. The primary clinical question was the source of the bleeding, but the examination revealed an unexpected congenital genitourinary anomaly. The left kidney was normally formed, whereas the right renal parenchyma was not identified. The right renal artery and vein were also absent. The right adrenal gland appeared elongated and flattened rather than normally triangular, and the right seminal vesicle was not clearly visualized. Taken together, these findings support congenital unilateral renal-seminal vesicle agenesis . The diagnostic lesson is broader than the diagnosis itself. An absent kidney on CT should never automatically be labeled renal agenesis. The radiologist should determine whether the missing kidney is truly absent, severely atrophic, ectopic, or surgically absent. The renal vessels, ipsilateral...
