Ruptured aneurysm of supraclinoid internal carotid artery with contained hematoma
Presentation
Severe headache
Patient Data
Bilobed out pouching is seen arising from lateral aspect of right supraclinoid internal carotid artery measuring approximately 18 x 16 mm.
Subacute hemorrhage measuring approximately 13 x 25 x 19 mm (AP x TD x CC) is seen at its posterolateral aspect, indenting the right cerebral peduncle, thalamus and medial temporal lobe.
Chronic lacunar infarcts and areas of ischemic demyelination are seen in bilateral periventricular, deep and subcortical white matter.
Convexity sulci and lateral ventricles are prominent, likely age related atrophy.
Case Discussion
Findings are suggestive of ruptured aneurysm of right supraclinoid internal carotid artery with contained subacute hematoma.
