Pseudo-meigs syndrome: uterine leiomyoma with bladder attachment associated with ascites and hydrothorax - a rare case of a rare syndrome.

INTRODUCTION: Pseudo-Meigs syndrome is a rare syndrome with pelvic tumors (not ovarian fibromas), which is combined with ascites and hydrothorax. Up to now 23 cases of pseudo-Meigs syndrome associated with uterine leiomyomas are described. We present a further case of a young woman with pseudo-Meigs syndrome combined with bladder attachment and elevated CA-125. CASE REPORT: A 27- year-old woman complained about increasing abdominal volume for about 2 months. Clinical results showed a normal sized uterus with a pedunculated leiomyoma, ascites, and a small pleural effusion. CA-125 levels were approximately more than 50 times higher than normal range. An explorative laparotomy revealed a leiomyoma and ascites. The myoma was attached to the posterior wall of the bladder; the rest of the uterus and both adnexae were normal. An organ-preserving operation was performed. Three months afterwards the patient presented normal clinical and sonographical findings and normal CA-125 serum levels. DISCUSSION: Uterine leiomyoma is only rarely associated with ascites and hydrothorax. Our case is the 24th in literature. Like other authors we could show elevated CA-125 serum levels. Cases of pseudo-Meigs syndrome with penduculated myomas and tight adhesions of neighbouring structures have been described frequently. In our case the bladder was tightly attached, and the vascularisation seemed to come from the uterus and the bladder. This atypical double supply might be in etiological context with the ascites. Pseudo- Meigs syndrome should be considered as a rare differential diagnosis for ascites and pleural effusions. Copyright 2002 S. Karger GmbH, Freiburg
