Meningioma

Case contributed by David Cuete
Diagnosis almost certain

Patient Data

Age: 35 years
Gender: Female
ct

CT shows a right frontal extra-axial mass with a dural tail, displacing the adjacent parenchyma in the right frontal lobe. The right lateral ventricle is partially effaced. The third and 4th ventricles are normal. The adjacent calvaria presents a permeative aspect with lytic areas and expansion of the diploe. Brainstem and cerebellum are normal. Basal subarachnoid cisterns are within normal range. No focal parenchymal lesions are observed.

mri

MRI revealed a mass showing intense extra-axial enhancement following the use of intravenous contrast with "dural tail", periosteal reaction and infiltration of the diploe and adjacent frontoparietal soft tissue. 

Incidental note is made of a small cavernous malformation in the white matter just lateral to the trigone of the left lateral ventricle. 

Case Discussion

Findings are consistent with a meningioma with extension into the frontal bone.
