title: [Pneumatocyst of the sacrum. Apropos of a case].
abstract: We report a new case of asymptomatic pneumatocyst of the sacrum in a 45-year-old man with a history of lumbago. Pneumatocysts are rare benign osseous lesions filled with gas and always found in the subchondral bone of the sacral or iliac side of the sacroiliac joint. The diagnosis is made by CT scan. In the sacral location, the pneumatocyst is asymptomatic and surgical treatment is not justified.
