The role of magnetic resonance in the diagnosis of intracranial berry aneurysm: A case report

Motivation: Headaches associated with intracranial aneurysms are often misdiagnosed and poorly understood in the Ghanaian population. Goal(s): Our goal was to use gadolinium-enhanced MR angiography to radiologically describe features of intracranial berry aneurysm (IBA) in a clinically asymptomatic patient presenting with right-sided headaches. Approach: Axial, sagittal and coronal brain MR angiography was conducted with 50 mg/ml gadolinium contrast and radiologically evaluated. Results: A right posterior communicating artery aneurysm was found, suggesting compression of the oculomotor nerve which is characteristic of IBA. Impact: The imaging findings could help physicians to better understand, diagnose and treat the underlining causes of constant right-sided headaches which may otherwise be poorly managed by patients themselves through self-medication as is the current practice in the Ghanaian setting.
