A 22-year-old female student presented with pain, early satiety, a dragging sensation in the abdomen, and weight gain. She had been diagnosed with irritable bowel syndrome several years prior based on the symptoms. Over the preceding 6 months, she reported increasing frequency of progressive nausea primarily with meals, emesis nearly every day, and constipation. She noted early satiety but no evidence of dysphagia or odynophagia. Overall, she had a 20-pound weight gain within 4 months prior to diagnosis. The patient had no significant past medical or surgical history. Within her family history, there was no history of ovarian disease, gastrointestinal malignancies, or cystic disease. She reported regular menstrual cycle with an age of menarche of 12. A pregnancy test at admission was negative. Prior to diagnosis she had taken to wearing exclusively yoga pants because belts were uncomfortable.Physical examination was notable for diffuse abdominal distention and a fluid wave without peritonitis or evidence of a hernia. Percussion was dull throughout. A CT scan of the abdomen and pelvis noted a large cystic mass with internal attenuation, occupying the majority of the abdomen with mass effect resulting in superior displacement of the liver, spleen, stomach, as well as the majority of the small bowel located in the left side of the abdomen (Figure 1). Tumor marker studies, including beta-HCG, CA 19-9, carcinoembryonic antigen, and CA125 were negative.After discussion of options including a laparoscopic approach, and the small but real risk of a cancer diagnosis, an open approach was judged best to avoid rupture of the cyst. The patient was taken to the operating room for an exploratory laparotomy. A 40-cm cyst arising from the right ovary was noted (Figure 2) and on full inspection of the abdomen there was a normal appearing uterus, normal left ovary and fallopian tube, normal pelvis and paraaortic lymph nodes, normal peritoneum, and normal bowel. Gynecologists, having obtained prior consent, performed a right oophorectomy and salpingectomy in continuity with the mass. She recovered rapidly with normal dietary intake. The final pathology of the 10.4 kg cyst was serous cystadenofibroma and ovary with hemorrhagic corpus luteum.
AbstractWe report a new perspective on the case of a 22-year-old female with no significant medical history who posed a diagnostic and therapeutic challenge; a giant cystic mass of the abdominal cavity. Work up was notable for no significant laboratory abnormalities but a large cystic lesion noted on imaging. The patient underwent open resection. A giant cystic abdominal tumor may present with the common and protean abdominal symptoms of bloating, pain, and early satiety from either mass effect or adhesions to surrounding structures. Caution is advised in attempting the laparoscopic resection of such tumors.
