A Pilocytic Astrocytoma Mimicking a Clinoidal Meningioma

A Pilocytic Astrocytoma Mimicking a Clinoidal Meningioma

Pilocytic astrocytomas and meningiomas are benign, primary brain tumors that may involve the optic tract. Classically, the presence of a dural “tail” sign may differentiate a meningioma from other intracranial lesions. In this report, we describe a mass with the typical appearance of a clinoidal men...
