Abstract

Ruptured dissecting superior cerebellar artery aneurysms are rare, and only 12 cases have been reported. We report a case of dissecting aneurysm of the distal superior cerebellar artery presenting with subarachnoid hemorrhage. An 80-year-old man presented with a three-day history of headache and diplopia. CT revealed slight subarachnoid hemorrhage and CT angiography demonstrated a dissecting aneurysm located in the distal portion of the left superior cerebellar artery. Initially, we chose conservative therapy. Ten days later, the patient became drowsy. Repeat CT showed that the amount of the subarachnoid hematoma increased and the aneurysm enlarged. Emergent endovascular coil embolization with parent artery occlusion was performed successfully. Postoperative MRI revealed no infarction in the cerebellum or brain stem. Delayed ischemic deficits were not observed after treatment. Endovascular parent artery occlusion of the distal superior cerebellar artery is an effective method with low morbidity for treatment of ruptured dissecting distal superior cerebellar artery aneurysms.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
