Aunt Mickey (They Look the Same until You Undress Them). Meningioma or Something Else?

73 year old lady presented with six weeks history of odd behavior, increasing apathy, expressive aphasia, and mild headache. An MRI including diffusion and perfusion imaging was obtained. MRI revealed a T1 hypointense (to cortex) and slightly T2 hyperintense (to cortex) extra-axial mass in the left frontal region. There were multiple central T2 hyperintense areas. On post contrast T1 weighted sequence, there was intense enhancement of the mass except the central T2 hyperintense areas.There were prominent diffusion restriction and high rCBV in most parts of the tumor in diffusion and perfusion imaging respectively.

At this point, what is your diagnosis? … Continue reading >>

Aunt Mickey (They Look the Same until You Undress Them). Meningioma or Something Else?

A young African American woman presented with progressive left vision loss.  Brain MRI with contrast and perfusion studies were obtained.  The studies showed a dural-based lesion involving the lateral aspect of the left cavernous sinus which extended superiorly and crossed the planum sphenoidale to insinuate itself around the contralateral anterior clinoid process. The lesion was isointense to gray matter on T1WI, dark on T2WI, showed homogeneous gadolinium enhancement and increased rCBV on the perfusion images (see below).  The provisional diagnosis of meningioma was made and the patient scheduled for surgical decompression of left optic canal.
