| ABSTRACT |
|
The authors analyzed the computed tomography(CT) findings in 69 patients with intracranial aneurysm. The indirect evidences for the diagnosis of an aneurysm in this series consisted of subarachnoid hemorrhage(53/69), intracerebral hematoma(24/69), dilatation of ventricle(19/69), infarction(8/69), intraventricular hematoma(7/69), and subdural hematoma(1/69). Visualization of aneurysms were possible in 6 out of 69 patients. In sites of blood by CT, the suprasellar cistern was most common and the sylvian cistern next. Ventricular dilatations were seen in the patients with aneurysm of internal carotid artery most commonly and next in those with anterior communicating artery. The higher the CT grade was, the poorer the clinical grade was and the more severe the vasospasm. Close correlation was present between the blood in CT and vasospasm. |
