Calcified meningioma of the anterior clinoid process

Case contributed by Dr Roberto Schubert

Presentation

Frontal headaches.

Patient Data

Age: 75 years
Gender: Female

There is a rounded lesion lateral to the supraclinoid portion of the right ICA, which is hypointense on both T1- and T2-weighted images.

The lesion has the same attenuation as the bone of the skull base and is contiguous with the right anterior clinoid process.

Case Discussion

The anterior clinoid process is an atypical location for a meningioma. These lesions may calcify and induce new bone formation. So a calcified or ossified meningioma is the most probable diagnosis.
