title: Multiple cerebral and leptomeningeal metastases from ovarian carcinoma: unusual early presentation.
abstract: Although virtually any systemic malignancy is capable of metastasizing to the brain, ovarian carcinoma, one of the more common female genital malignancies, is one of the rarer forms of brain metastases. In general, the outcome for ovarian carcinoma with brain metastases is extremely poor as most of these patients have widespread lesions elsewhere. This report describes the first known case of multiple cerebral and leptomeningeal metastases as the initial manifestation of ovarian carcinoma in a 41-year old woman who presented with a one-week history of headache, vomiting and confusion. CT scan of the brain was unremarkable, but lumbar puncture revealed atypical cells in the CSF. MRI scan of the brain showed multiple small enhancing lesions. Craniotomy for excision of one of these lesions demonstrated metastatic adenocarcinoma. A large ovarian tumour identified on pelvic CT scan was resected and the patient subsequently received chemotherapy and radiotherapy. Unfortunately she continued to decline and died within six months. Unlike primary tumours such as malignant melanoma, ovarian carcinoma does not have a predilection for the central nervous system (CNS), but the rare instances with CNS involvement occur at an advanced stage of the disease. Once the CNS is involved, the outcome is abysmal, even with multimodality therapy. It is extremely unusual for ovarian carcinoma to present with multiple CNS involvement.
