    Abstract:
    The convexity angiomatous meningiomas that occurred in a mother and a daughter without any evidence of neurofibromatosis (NF) were reported. The 73-year-old mother was admitted to our clinic because of an episode of generalized convulsion and a five-month history of gait disturbance. She had the signs/symptoms of intracranial hypertension and frontal lobe dysfunctions. Computed tomography (CT) revealed a left frontal enhanced mass with a small intratumoral cyst and a remarkable perifocal edema. Angiography showed tumor stain fed from the external carotid artery. Frontal craniotomy was performed and a dark red tumor was totally resected. The nodular-surfaced tumor had adhered loosely to the dura mater. The coarse vascular meshwork and an intratumoral cyst were observed on the cut surface. When the patient was discharged she was able to leave the hospital on foot, but she died of acute pancreatitis in the local hospital. Histological examination of the tumor showed rich vasculatures with focally whorl-formed cells. Most tumor cells had intracytoplasmic microcysts. The pathological diagnosis, WHO's classification, 1991, was angiomatous meningioma. The patient's 41-year-old daughter was admitted due to an episode of fainting. All laboratory data were within normal limits, including the normal karyotype of the peripheral blood leukocytes. Papilloedemata were the only signs of neurological deficit. A CT scan and magnetic resonance images showed a left frontal convexity mass and angiography displayed the tumor strains from the middle meningeal artery. The convexity meningioma similar to her mother's was totally removed. The histological diagnosis was angiomatous meningioma, again.(ABSTRACT TRUNCATED AT 250 WORDS)
