ABSTRACT
In the present shdy 9 patients with the radiological diagnosis of intracranial fusiform aneurysms are included. All patients were subjected to [1] Full clinical examination [2] Studies for diabetes, lipid profile and serum lipid electrophoresis, ECG [3] CT scan or MRI examination of the brain [4] Conventional 4 vessel angiography or magnetic resonance angiography. All fusiform aneurysms were nicely visualized by CT scan, MRI and angiography. According to the existing parenchymal brain pathology, patients were classified into three main groups as follows. Group [1] patients with ischemic parenchymal changes that are probably not causally related to the existing fusiform aneurysms [33%], group [2] patients with ischemic parenchymal changes that could be causally related to the existing fusiform aneurysms [33%] and group [3] patients without any parenchymal brain changes other than brain stem indentation by the aneuryms. Correlation between the fusiform aneuryms, the clinical picture of the patients and the associated parenchymal brain changes will be presented and discussed. Full description of the radiological picture of these extremely uncommon aneurysms and how they are implicated in pathogenesis and in symptom formation will be made. Also the impact of these aneurysms on patient's management will be discussed
