Meningioangiomatosis Without Neurofibromatosis Type 2.

Meningioangiomatosis (MA) is a rare, benign hamartomatous lesion found in cerebral cortex and leptomeninges. It occurs mostly in 5 - 15 year old children in form isolated or diffuse; the diffuse form may be associated with neurofibromatosis type 2 (NF2). The sporadic type in the adults is less common.The patient was a 37 year-old man with a long history of frontal headache. In suspected sinusitis, the patient underwent cerebral MRI that showed hypointense lesion in the right frontal lobe with heterogeneous contrast enhancement after gadolinium administration. There were no stigmata or family history of neurofibromatosis. A right pterional approach with a supraorbital craniotomy was performed. The lesion was removed with complete remission of the headache in the postoperative time. MA enters into differential diagnosis with several other diseases and a correct diagnosis is mandatory. The total surgical removal is the treatment of choice, and the prognosis after surgery is usually excellent for the absence of recurrence in sporadic cases.
