A 17-year-old female presented with a small pontine hematoma considered as having arisen from rupture of a capillary telangiectasis. Vertebral angiography showed fenestration of the left distal vertebral artery without any vascular anomaly in the pons. Histological examination of the surgical specimen verified the presence of a capillary telangiectasis adjacent to the hematoma. Rupture of a capillary telangiectasis as the source of pontine hematoma is very rarely documented histologically in surviving patients.
