Foramen magnum meningioma

Case contributed by Dr Mohammad A. ElBeialy

Presentation

Headache and bilateral upper limb paraesthesia

Patient Data

Age: 40 years
Gender: Female
Modality: MRI

Dorsal foramen magnum mass is seen compressing the cervicomedullary junction and upper cervical cord. Post contrast images appear to have limited contrast (note paucity of mucosal enhancement) and as such a comment on enhancement characteristics of this mass is difficult.  Mega-cisterna magna is incidentally noted. 

Case Discussion

Meningiomas are a common primary intracranial neoplasm but location at the foramen magnum is uncommon - accounting for ~2.5% (range 1.8-3.2%) of meningiomas 1
