Very few cases of this vascular anomaly have been published from West Africa. We report the first case of a ruptured pericallosal artery (PCA) aneurysm managed in a Nigerian neurosurgical facility, with the aim to add to the limited documentation on vascular brain lesions in our sub-region. The management outcome of the index patient and a literature review on these unusual aneurysms were also discussed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case report<\/jats:title>\n                    <jats:p>A middle-aged known hypertensive woman who presented with clinical features of a WFNS grade I subarachnoid hemorrhage (SAH). A plain cranial computerized tomography (CT) scan revealed SAH, a supracallosal intracerebral hematoma and intraventricular hemorrhage. Cranial computerized tomography angiography (CTA) showed a small right pericallosal artery aneurysm, which was treated (with clipping via an interhemispheric approach) in a resource-constrained neurosurgical facility. The patient has remained well over a six-year follow-up period.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>PCA aneurysms have a high tendency to bleed compared with other supratentorial intracranial aneurysms in spite of their small size.
