| ABSTRACT |
|
A 35-year-old man, with a previous history of intermittent generalized seizure attacks since 13 years of age, presented with status epilepticus and spastic right hemiparesis. Plain skull films showed a mottled, granular calcified core and a surrounding halo of calcification in the subcortical area of the central fissure, and a smooth erosion of the overlying skull inner table. Left carotid angiogram revealed neither definite mass effect nor abnormal vascularities. Surgery through a left parietal craniotomy was performed. Upon direct inspection of the brain a 2.5+/-3.0cm, stony hard, generally circular mass was noted within the left frontal lobe. Although embedded within the frontal lobe, the mass was partially covered by a gliotic cyst which might be made from cortical tissue. The tumor was obviously calcified, demonstrating numerous superficial white excrescences, and readily removed without difficulty. Microscopic, pathological evaluation confirmed the diagnosis of densely calcified arteriovenous malformation. The patient was discharged without any evidence of neurological deficit except dull mentality. |
