Abstract

Meningeal metastasis is rare in the clinical course of ovarian carcinoma and its prognosis is extremely poor. We experienced a case of carcinomatous meningitis from metastatic ovarian small cell carcinoma. A 33-year-old woman with atypical genital bleeding, was diagnosed with a right ovarian tumor and referred to our department. She underwent a total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and lymphadenectomy. It was an optimal debulking surgery. She was diagnosed with ovarian carcinoma classified as Stage IIIc according to the Féderation Internationale de Gynécologie et d'Obstétrique classification system. Histological findings showed small cell carcinoma of the pulmonary type. The tumor was bilateral with paraaortic lymph node involvement. The patient was treated with irinotecan and cisplatin (CPT-P therapy). After 4 courses of CPT-P therapy, multiple liver metastases and Virchow's lymph node metastases were found. She was treated with amrubicin as a second-line chemotherapy, but the treatment was ineffective. Five months after surgery, the patient complained of severe headache and nausea. Lumbar puncture was performed and cytology was positive. Magnetic resonance brain imaging indicated meningeal thickening. The patient was diagnosed with meningeal metastasis and received 19-Gy whole cranial irradiation. In spite of these treatments, her disease progressed rapidly and she was often drowsy. She died of aspiration pneumonia 6 months after surgery.
