title: [Cranial sarcoidosis with an unusual location in the orbital vertex].
abstract: Bone sarcoidosis preferentially localizes in skull bones with long lasting skin lesions, (its manifestation in skull are rare and there are only 12 or 13 published cases) and the bone involvement of the cranial basis has been referred, until now, as extensive lesions of granulomas localized in neighbouring structures. We present a case of cranial basis granulomatosis, in a patient diagnosed of multiple sarcoidosis by repetitive biopsies of lymph nodes, liver, and skin with chronic skin lesions, the rare localization of which in the orbital vertex with an original bone procedence, is discussed in the neuroradiologic findings. Such rareness has been found in a carrier of a form of common variable immunodeficiency, a disease which is also rare.
