A Pilocytic Astrocytoma Mimicking a Clinoidal Meningioma

الملخص EN

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 meningioma on magnetic resonance imaging (MRI) but postoperatively diagnosed as a pilocytic astrocytoma.

This case illustrates the rare occurrence of a pilocytic astrocytoma mimicking a meningioma on MRI.
