Rhabdoid meningioma

Case contributed by Dr Azza Elgendy



Patient Data

Age: 20
Gender: Female

Axial NECT shows mixed solid (hyperdense) and cystic right frontal intra-axial mass with extensive vasogenic edema and mass effect. 


Large mixed solid and cystic mass located in the right frontal lobe. The solid component is isointense in relation to the grey matter. There is mass effect on anterior horns of lateral ventricle and 10 mm leftward shift. 


Case Discussion

There is a marginated, mixed solid and cystic mass lesion seen involving the right frontal lobe. It causes mass effect on the bifrontal horns, genu of CC, and 10 mm left ward shift. The mass is surrounded by a marked vasogenic edema that extends to the insular subcortical white matter. It is iso intense to the grey matter on T1WI. It shows marginal and nodular enhancement following contrast administration. There are also some susceptibility artefacts suggestive of blood products versus calcifications. 

Patient had a resection and the biopsy demonstrated a malignant meningioma with rhabdoid features, likely meningeal in origin (WHO grade III).

Meningioma with rhabdoid morphology is associated with a poor prognosis, regardless of tumor histogenesis.
