Abstract
Benign meningeal neoplasms such as meningiomas and granular cell tumors are characteristically well circumscribed, spherical, gray-white discolored masses or thickenings, intimately connected with the meninges. The meninges over the frontal, parietal, and temporal portion of the cerebrum and the dorsal and lateral portions of the cerebellum are the most frequent anatomic locations for these neoplasms. Averaging less than 3 mm in diameter, benign meningeal neoplasms range from 1 mm to 10 mm. Larger tumors grow by expansion causing compression of the adjacent brain tissue, with sharp demarcation from surrounding tissue and no invasion into the brain parenchyma.
