Meningioma with high T2 signal

Case contributed by A.Prof Frank Gaillard
Modality: MRI

An intensely high T2 signal extra-axial mass with vivid contrast enhancement and a dural tail (best seen on coronal) is seen in the left middle cranial fossa. 

The patient went on to have a resection. 

Histology

Microscopic Description:  Sections show small pieces of a relatively hypocellular tumour displaying numerous hyalinized capillaries. A few foci of recognizable meningioma are seen. Areas of sclerosis are also noted. Brain tissue is not identified.

Final Diagnosis: Meningioma (WHO grade 1).

Case Discussion

It is important to realize that some meningiomas, especially microcystic, secretory and angiomatous variants can be very bright on T2.
