[Dissecting aneurysm of the middle cerebral artery with subarachnoid hemorrhage undetectable on preoperative neuroradiological findings: case report].
We report a rare case of a dissecting aneurysm (DA) of the middle cerebral artery(MCA) associated with subarachnoid hemorrhage(SAH) undetectable on preoperative neuroradiological findings. A 64-year-old man was admitted to our hospital because of a sudden onset of occipital headache. CT scan showed SAH mainly in the basal cisterns and left sylvian fissure. ⋯ The postoperative course was uneventful and the patient was discharged without neurological deficits. There has been no rebleeding nor new ischemic attack during the ten months since surgery. The 20 reported cases of a DA of the MCA associated with SAH with our case are reviewed and their neuroradiological and clinical features are discussed.
