Background: Intracranial aneurysms are a major cause of subarachnoid haemorrhage and contribute significantly to neurological morbidity and mortality. Understanding their demographic and radiological distribution is essential for early diagnosis and risk stratification.
Aim: To evaluate the demographic profile, clinical presentation, and radiological distribution of intracranial aneurysms in a tertiary care hospital.
Materials and Methods: This hospital-based cross-sectional observational study included 91 patients diagnosed with intracranial aneurysms on CT angiography and/or digital subtraction angiography. Demographic details, clinical presentation, aneurysm location, number, and circulation involvement were analysed using descriptive statistics.
Results: Intracranial aneurysms were more frequently observed in females, with peak incidence in the fifth and sixth decades of life. The majority of patients presented with symptoms of subarachnoid haemorrhage. Anterior circulation aneurysms predominated, with the middle cerebral artery, internal carotid artery, and anterior communicating artery being the most commonly involved sites. Most patients harboured a single aneurysm, while multiple aneurysms were less common.
Conclusion: Intracranial aneurysms in this cohort showed a clear female predominance and anterior circulation dominance. Knowledge of demographic trends and anatomical distribution may aid in early recognition and optimized imaging evaluation.
