Post-contrast coronal T1-weighted sequence in a 63-year-old man with a remote history of follicular lymphoma demonstrates an extra-axial mass within the right middle cranial fossa with a broad dural attachment and dural thickening with intra axial extension into the right temporal lobe. There is homogeneous enhancement of the dural component and mildly heterogeneous enhancement of the intra-axial component. There is surrounding oedema and mass effect. Appearances could represent a meningioma with intra-axial extension, however were found to be lymphoma at histology
