Subarachnoid hemorrhage is a neurological emergency often caused by ruptured cerebral aneurysms, necessitating prompt imaging for accurate diagnosis and treatment. A prospective cross-sectional study was conducted in the Radiology Department of Jinnah Postgraduate Medical Centre (JPMC), Karachi, from July 2023 to July 2024. The study included 190 patients aged 18–60 years who were diagnosed with SAH on non-contrast CT brain. All patients subsequently underwent multidetector CT angiography to detect cerebral aneurysms. Demographic and clinical data, including age, gender, BMI, and symptom duration, were recorded. The frequency and location of detected aneurysms were analyzed. The mean age of patients was 39.5 ± 6.77 years, and the mean BMI was 29.63 ± 3.08 kg/m². Males represented 80.1% of the sample, while females comprised 19.9%. Overall, 81.3% of patients had cerebral aneurysms. Interestingly, aneurysm prevalence was higher in females (91.4%) than in males (78.7%), despite their lower proportion. A slightly higher prevalence was also observed in the 18–40 age group (84.2%) compared to the 41–60 group (80.4%). The most frequent aneurysm locations were the anterior communicating artery (28.7%), middle cerebral artery (28.3%), and posterior communicating artery (22.9%). Cerebral aneurysms were highly prevalent among SAH patients, with a notable predominance in females and in the anterior circulation. CT angiography proved to be an effective non-invasive tool for early diagnosis, underscoring its critical role in managing SAH cases promptly and accurately.
