Vertebro-basilar dolichoectasia is a rare cause of cerebello-pontine angle mass lesions [1]. These lesions are due to atherosclerotic and degenerative changes affecting the media of the arteries leading to fusiform enlargement. Usually seen in patients more than 50 years of age, it may cause brain stem infarction, compression or cranial nerve palsies. CT angiography is a non-invasive and accurate modality of imaging these vascular lesions. We report a case of vertebro-basilar dolichoectasia with fusiform aneurysm and intraluminal thrombus, diagnosed using 3-D CT angiography. |
