An 11-year-old white girl presenting with fever, dyspnea, and cough demonstrated a left pleural effusion, ascites, and a suprapubic mass on physical and radiologic examinations. Surgical resection of the mass found a stage Ic malignant mixed germ cell tumor of the ovary. The pleural effusion and ascites were benign and resolved spontaneously after complete resection of the tumor, which is characteristic of a pseudo-Meigs syndrome.
