Accurate stroke diagnosis has a high significance for patient's outcome. Computed tomography (CT) brain scan is the imaging of choice for patients presenting to the emergency department with stroke. Aim and Objectives: The study aimed at evaluating the pattern of lesion depicted on CT brain of patients presenting with stroke in ABUTH, Zaria. Materials and Methods: A prospective review of CT findings in 155 patients who presented in the Radiology Department of Ahmadu Bello University Teaching Hospital (ABUTH) with clinical diagnosis of stroke was undertaken over a period of six months (from October 2017 to April 2018).. Results: Of the 155 patients seen within the period under review, 88 (56.8%) were males while 67 (43.2%) were females. Age range was 11-90 years (mean 56, standard deviation (SD) 16, 44(28.4%) of patients were in the age group of 61-70 years. Ninety six patients (61.9%) had ischaemic stroke, 27(17.4%) had hemorrhagic stroke, eight (5.2%) was stroke mimic, six patients (3.9%) mixed lesions (ie both ischaemic and haemorrhagic). Eighteen patients (11.6%) had normal brain CT findings. The region most affected by stroke was the parietal region 52(38%). Conclusion: Ischaemic stroke is the most common form of stroke in this study.
