Well-circumscribed lobulated extra-axial mass at the foramen magnum, lateralised to the left, measuring 34 x 28 x 24 mm and extending to the ipsilateral hypoglossal canal. It displays an isosignal to the grey matter on T1, T2 and FLAIR. The post-contrast sequences demonstrate a vivid heterogeneous enhancement with small central cystic areas. The medulla oblongata is compressed and displaced to the right. No significant dilatation of the ventricular system.
Small right parietal lesion with blooming artifact on GE sequence suggestive of cavernoma.
