Case Reports
[Ruptured distal anterior cerebral artery aneurysm and diagnostic dyspraxia: a case report].
A case of ruptured distal anterior cerebral artery aneurysm presenting with diagnostic dyspraxia is presented. A 54-year-old female was referred to our hospital with the complaint of sudden onset of headache followed by disturbance of consciousness. CT and MRI revealed subarachnoid hemorrhage with hematomas in the interhemispheric fissure and the supracallosal area, and CAG revealed a left-sided callosomarginal artery aneurysm. ⋯ It disappeared gradually over a period of one year. Involuntary motor behavior of the left hand while the right hand is in voluntary action is known as diagnostic dyspraxia. Although this symptom has rarely been reported so far in cases of ruptured distal anterior cerebral artery, it may become noticed more frequently through careful observation.
