Aneurysm of the distal anterior inferior cerebellar artery unrelated to the cerebellopontine angle: case report.

This is a case report of an unusual aneurysm of the distal anterior inferior cerebellar artery. A 44-year-old woman had a severe frontal headache and vomiting of sudden onset. On the day after admission, the patient began to demonstrate nuchal rigidity and difficulty with upward gaze bilaterally. There were no complaints at this time suggestive of a syndrome of the cerebellopontine angle. A computed tomographic scan revealed an intraventricular hemorrhage of the 3rd and 4th ventricles; however, multiple attempts at four-vessel angiography were required before an aneurysm could be demonstrated. On the 28th hospital day, a suboccipital craniectomy using the retromastoid approach in the lateral position was performed. A saccular aneurysm with a surrounding hematoma in the distal anterior inferior cerebellar artery was found and clipped. The operative findings revealed that the aneurysm was unrelated to the cerebellopontine angle. After surgery, the patient had an uneventful recovery and complete resolution of symptoms.

Angiography before and after radiotherapy for a thalamic tumor

SummaryA patient with a thalamic tumor received radiotherapy. A right cerebral angiogram seven days after the irradiation was finished revealed increased vascularity, early filled deep cerebral veins and signs of increased mass. A subsequent angiogram showed gradual regression of these features. There is no literature on angiographic progression with early venous filling following radiotherapy.

52. Neurological Analysis on Surgical Indication of Hypertensive Intracerebral Hemorrhage and its Results

2) The recovery of hemiplegia could not be expected in cases with hematoma extended into lateral ventricle destructing the internal capsule. The major aim of surgery is life saving in these cases. 3) The prognosis for hemiplegia by the surgical evacuation was significantly better than that of conservative management in cases with the hematoma spread into a part of the posterior limb of internal capsule. Surgery is advisable for this type of hemorrhage. 4) The severity and prognosis of hemiplegia in putanimal hemorrhage was
