Archive Of Radiology Images: Cranial Meningioma Findings

OVERVIEW

This page is dedicated to providing an organized archive of images that demonstrate the appearance of a cranial meningioma. This archive is organized by the type of finding that is characteristic for a cranial meningioma.

It is recommended to read this page as a primer: Condition Specific Radiology: Cranial Meningioma

WHAT ARE THE CHARACTERISTIC FINDINGS OF A CRANIAL MENINGIOMA?

This archive will focus on providing images that demonstrate the following characteristic findings of a cranial meningioma:

Dural tail: given the nature of this tumor, and its dural origin, often a “dural tail” can be visualized on imaging that is fairly characteristic of a meningioma.

CSF in the “cleft”: given the nature of the tumor, CSF will often be “trapped” in the area (or “cleft”) between the tumor and the brain.

DURAL TAIL

Example # 1: 

Appearance of meningioma on a T1 weighted MRI image before and after contrast enhancement. The characteristic "dural tail" can be seen on the right pane with enhancement (source).

Example #2:

CSF IN THE CLEFT

Example #1: 

T2 axial image of a cranial meningioma. The arrow points to the presence of CSF in the "cleft" between the tumor and brain parenchyma. This is a feature that is characteristic of a meningioma (source)
