case_images: CT scan of a slightly rounded hyper density process of the extra-axial front anterior skull base sitting at the olfactory groove area with significant hypo density peri-lesional oedema on the toe finger more marked on the right and hyperostosis in regard of the lesion

case_images: Then we performed a cerebral CT scan (Figure 1) which show a slightly rounded hyper-density process of the extra axial front floor sitting at the olfactory groove area with significant hypo-density peri-lesional oedema on the toe finger more marked on the right and hyper-osterosis in regard of the lesion.
case_images: MRI scan of T1 lesion hypo intensity extra axial anterior skull base fronto ethmoidal area; in T2 lesion hyper intensity this lesion was homogenous inhancing after gadolinium injection

case_images: Secondary the cerebral MRI scan (Figure 2) revelead the presence 4x4x4 cm well enhanced meningioma extra axial mass of the anterior skull base with peri-tumoral oedema corresponding to an olfactory groove meningioma.
