OB/Gyn - Pelvic Cystic Mass
Caption
A middle-aged female with a history of colon cancer presented to the ED with constipation and abdominal pain. A recent colonoscopy had revealed rectosigmoid adenocarcinoma. Her physical exam was notable for a distended abdomen that was tender to palpation. POCUS revealed the presence of a large, complex, cystic structure within the pelvis. Subsequent CT confirmed a loculated fluid collection within the pelvis compressing the rectum and sigmoid colon; this mechanical obstruction was likely contributing to patient’s constipation. Differential diagnosis included loculated ascites versus cystic tumor. Kyla Walworth, MS-4 & Matthew McDowell, PGY-1 Central Michigan University College of Medicine
