Intracranial aneurysm and arachnoid cyst: just a coincidence? A case report

ABSTRACT

CONTEXT:

Presence of an arachnoid cyst and a non-ruptured intracystic brain aneurysm is extremely rare. The aim of this paper was to describe a case of a patient with an arachnoid cyst and a non-ruptured aneurysm inside it. Clinical, surgical and radiological data were analyzed and the literature was reviewed.

CASE REPORT:

A patient complained of chronic headache. She was diagnosed as having a temporal arachnoid cyst and a non-ruptured middle cerebral artery aneurysm inside it. Surgery was performed to clip the aneurysm and fenestrate the cyst.

CONCLUSIONS:

This report raises awareness about the importance of intracranial vascular investigation in patients with arachnoid cysts and brain hemorrhage.
