A case of multiple simultaneous intracerebral hematomas is presented. A 80-year-old man who had sudden onset of right hemiparesis and consciousness disturbance was admitted to our hospital. He had a long history of hypertension. A computed tomographic (CT) scan was performed immediately. It demonstrated a left thalamic hemorrhage and a left pontine hemorrhage. No abnormal vessel was recognized on enhanced CT scans, magnetic resonance (MR) images and MR angiography undertaken thereafter. Although he was treated conservatively, his consciousness was not improved after about 2 months of hospitalization. The occurrence of multiple simultaneous intracerebral hematomas is rare in this country. It develops only in a small number of patients who have intraparenchymal hemorrhage. The outcome is poor in the majority of these cases. The prognosis for survival is poor.

External decompression was performed on four patients with head trauma and one patient with meningioma. Cranioplasty was done for correcting sknll defeets in these parients later using. Eight ceramic bones. Ceramic bones were made on 3-dimenssional solid models with cranial defects reconstructed based on data of computed tomography scan. The artifical bones conformed to the acutual cranial defects perfectly. Ceramic bone was thought to be suitable for correcting big cranial defects in cosmetic respects. Two complications were observed in these patients during the average follow-up period of ten months. One complication case was infection of artificial bone, and the other was post-operative epidural hematoma. When the size of articial bone was big or the shape of that was strongly curved, we had to pay attention to the tacking of dura during operation.

Metastasis of ovarian malignancy to the central nervous system (CNS) is still rare.
We report a case of a 48-year-old woman with brain metastasis of serous cyst adenocar-cinoma of the ovary as the primary site. Metastasis occurred when postoperative combination chemotherapy and radiation therapy were being given to the patient after complete surgical removal of ovarian tumors. A review of the literature is also made.

We report a case of a 17-year-old man with subarachnoid hemorrhage (SAH). SAH was from ruptured of an aneurysm of the left middle cerebral artery, for which the clipping was performed. After the surgery, vasospasm was observed by angiographyand the arterial injection of HCI-papaverine was done. A review of the literature is also made.
