Patient Data

Age: 63
Gender: Male

CT Brain

Non contrast study: a mass of heterogeneous attenuation is observed with a tubular aspect and well defined, that presents with compressive effect on the brain stem and third ventricle. There is supratentorial ventricular dilatation (hydrocephalus).

Contrast phases confirmed that it was a tortuous basilar artery, elongated and with a important thrombosed aneurysmal dilatation.

Case Discussion

The basilar artery is part of the posterior cerebral circulation. The basilar artery arises from the confluence of the left and right vertebral arteries at the base of the pons as they rise towards the base of the brain.

This case is compatible with chronic obstructive hydrocephalus caused by giant basilar artery aneurysm.
