Abstract: Posterior circulation stroke (PCS) accounts for very high mortality rates. Early characterization of the stroke type and location will contribute to better patient outcomes. The objective of the study was to determine the infratentorial region commonly affected by PCS and the type of stroke, as well as ascertain how common IPCS is in our environment. The study was carried out on 179 patients with infratentorial stroke out of a total 569 patients with stroke in a Radio-diagnostic Center in Jos, North Central Nigeria. Cranial Computed Tomography findings of stroke in the posterior cerebral circulation depicting the type of stroke as well as the affected regions of the infratentorium were gotten and analyzed for demographic data, frequencies, and pattern of distribution. Infratentorial stroke was seen in 179 patients. Mean age was 55 years, with male preponderance of about 58%. Total number of patients with brainstem and cerebellar strokes was 179 (31.4%), affecting the cerebellum in 12.6% of the patients and the brainstem in 18.8%. 138 (77.1%) of the 179 patients with IPCS had ischemic stroke. Ischemic stroke in the cerebellum accounted for 53 (9.3%) patients, and in the brainstem 85 (14.9%) patients. Hemorrhage into the cerebellum and brainstem were in 19 (3.3%) and 20 (3.5%) respectively. The pons is slightly more affected than the cerebellum, while the medulla is the least affected region of the brainstem. There is an increase in the incidence of posterior circulation stroke. Ischemic stroke is the more common type of IPCS. The brainstem is more commonly affected than the cerebellum.
