Sarcoidosis presenting as an osteolytic skull lesion: a case report and review of literature on skull sarcoidosis

摘要

Bone sarcoidosis of the skull is an infrequent presentation of sarcoidosis. We describe a 51-year-old man who consulted due to inflammatory-appearing nodulation in the right supraorbital region. Images showed a solitary osteolytic lesion extending to soft tissues with increased scintigraphic uptake. The anatomopathological study revealed the presence of non-caseating epithelioid granulomas, compatible with sarcoidosis. Steroid treatment led to a marked remission of the lesion, without evidence of relapse during a follow-up period of 1 year. The literature dealing with skull sarcoidosis is reviewed.
