RESUMO
Atraumatic Non-aneurysmal sulcal subarachnoid hemorrhage is very rare. Sulcal subarachnoid hemorrhage (sSAH) is characterized by isolated bleeding in one or a few adjacent sulci. Central sulcus hemorrhage is a rare imaging finding. There are many causes for sSAH. In older patients, sSAH is due to Cerebral Amyloid Angiopathy (CAA), while in younger patients, reversible cerebral vasoconstriction syndrome (RCVS) is the most frequent etiology. Imaging studies help in the evaluation of sSAH. We report a rare case of an isolated central sulcus hemorrhage on computed tomography. sSAH usually occur on the side with acute ischemic stroke, and it is unusual for sSAH to occur on the opposite side of the infarct territory, but in our case sSAH occurred on opposite side, but after a gap of 3 years.
