There were thirty-two autopsied cases of ruptured aneurysms at the junction of the internal carotid and posterior communicating arteries in the file of Montefiore Medical Center from 1948 to 1983 (Table 1). The age range of the patients was 11-83 years. Seven were men and twenty-five were women. ⋯ These aneurysms did not produce a large intracerebral hematoma in the temporal lobe because they ruptured into the temporal horn. Among the post-operative cases (14 cases), only 3 cases had intraventricular hemorrhage. Correlation of these autopsy findings with CT Scans revealed that an intraventricular hematoma in the temporal horn could be interpreted as a large intracerebral hematoma in the temporal lobe.

In the literature, postoperative calcified epidural hematoma is not common. The authors report a case of calcified epidural hematoma after ventriculoperitoneal shunt, and radiotherapy for pinealoma. A 14-year-old boy was admitted to author's department on December 9, 1983, complaining of headache. ⋯ No inflammatory finding was seen on histological examination. The postoperative course was uneventful. Etiology of calcified intracranial hematoma was discussed in relation to the present report, the relevant literature reviewed.
