Meningioangiomatosis is a rare hamartomatous lesion or meningiovascular malformation in brain. In extremely rare condition, meningioma may occur together with meningioangiomatosis, and only 19 cases have been described in English literature until now. We now report a case of meningioangiomatosis-associated meningioma with atypical and clear cell variant. A 34-year-old man presented a 3-month hi...

Meningioangiomatosis is a rare benign hamartomatous lesion. We describe a case of meningioangiomatosis in an 18-year-old boy with a 15 year history of seizures. Computed tomography reveals an irregular calcification density along the right temporal gyrus. Microscopically, irregularly branched blood vessels, surrounded by a concentric arrangement of proliferating spindle cells, are extending int...

Meningioangiomatosis is a rare condition, probably hamartomatous, characterized by proliferation of capillary-sized vessels, meningothelial cells, and fibroblasts within the cortex of the brain. Lesions may be single or diffuse and may be associated with neurofibromatosis type II. Clinically it presents with seizures but may be asymptomatic throughout life. We report 3 cases of meningioangiomat...

BACKGROUND Meningioangiomatosis (MA) is a rare hamartomatous lesion. Only six cases of cystic MA have been reported in the literature. CASE PRESENTATION We present a case of multicystic MA. A 21-year-old woman without any stigmata of neurofibromatosis type 2 presented with intractable seizures since 10 years. Brain magnetic resonance imaging revealed a well-defined, multicystic mass with hete...

A 16-year-old young male experienced persistent headache, and brain computed tomography and magnetic resonance imaging showed an abnormal mass with calcification in the right temporal lobe of the cerebrum. The tumor was located in the leptomeninges and cerebral cortex. In the leptomeninges, multiple calcified-fibrous nodules were noted. In this area spindle-shaped cells were arranged in a fasci...

Meningioangiomatosis is regarded as a rare benign hamartomatous condition mostly involving the cerebral cortex and overlying leptomeninges. A strong association of MA with neurofibromatosis type 2 has been documented in published articles. Herein we report a case of an otherwise healthy 13-year-old boy with no family history or stigmata of neurofibromatosis who presented with intractable seizur...
