title: Intracerebral hemorrhage cause by a ruptured oncotic aneurysm from choriocarcinoma metastasis.
abstract: Ruptured oncotic aneurysms from choriocarcioma metastasis are very rare. One rare case of metastatic cerebral choriocarcioma with an initial presentation of intracerebral hemorrhage is reported. A 25-year-old woman initially presented with sudden onset of alteration of consciousness. The computed tomography scan showed left parietal hematoma and CT angiography showed a small aneurysm of the left middle cerebral arteries territories. Her chest X-ray showed two lung masses. A craniectomy was performed to remove the hematoma and decompression following the aneurysm excision. After surgery the patient regained consciousness and had no neurological deficit. The pathology reported metastatic choriocarcioma and her beta - HCG was 73,656 units. After recovery she received chemotherapy with an etoposide, methotrexate, actinomycin D, cyclophosphamide, and vincristine/oncovine (EMA-CO) regimen.
