Subarachnoid hemorrhage (SAH) caused by a dissecting aneurysm of the anterior inferior cerebellar artery (AICA) is rare. Partial coil embolization of the AICA may be an effective treatment. A 65-year-old woman presented at the emergency room with headache and vomiting for the past five days, after contracting coronavirus disease (COVID)-19. Computed tomography (CT) revealed SAH and intraventricular hemorrhage, and the patient was diagnosed with a dissecting aneurysm of the AICA. The patient underwent endovascular surgery, and the AICA was partially occluded using coiling, with no subsequent hearing disturbance, cranial nerve palsy, or infarction. Ventriculoperitoneal shunt surgery was performed for hydrocephalus at 7 weeks after SAH. The patient was discharged from hospital with no neurological deficit. We reported a rare case of ruptured AICA dissecting aneurysm, which was treated by partial coil embolization without neurological deficit or infarction.
