Giant ovarian cyst mimicking ascites.

Abstract

A 60-year-old female patient presented to our clinic with complaints of abdominal distention. The rapid accumulation of fluid was originally thought to be ascites, based on ultrasonographic examination. The cause, however, was ultimately determined to be a borderline malignant giant ovarian cyst. Several processes can mimick ascites: bladder distention or diverticulum, hydronephrosis, pancreatic pseudocysts, and large uterine or ovarian tumors. For this reason, clinicians must consider processes other than ascites in the differential diagnosis of large abdominal fluid accumulation.
