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.
