Takayasu arteritis with multiple intracranial aneurysms. A case report.

CONCLUSIONS

A rare case of multiple cerebral aneurysms associated with Takayasu aortitis is reported. Only seven cases have been reported so far, all of which are from Japan. This is the first case with this association being reported from India. A 50-year-old hypertensive woman developed sudden onset severe headache and loss of consciousness. CT scan revealed subarachnoid haemorrhage in the suprasellar cisterns and mild hydrocephalus. The patient on admission had a rebleed producing a massive subarachnoid haemorrhage. Angiogram revealed occlusion of bilateral vertebral arteries and right common carotid artery. The left carotid artery was ectatic with saccular aneurysms in the ophthalmic segment and communicating segment. Aortogram showed the radiological picture of Takayasu arteritis Type III. Surgical clipping of the aneurysms was performed. However, the patient developed a massive right cerebral infarct in the postoperative period following which she expired. Abnormal haemodynamics in the overloaded cerebral circulation rather than primary arteritic involvement of intracranial vessels appears to be the cause of aneurysm formation.
