[Neurosarcoidosis: presentation of 14 cases].

Multiple atypical bone involvement in sarcoidosis.

We describe a patient with right paratracheal and left hilar lymph nodes detected by chance on chest radiography that followed a spontaneous remission. However, a few months later she complained of multiple scalp nodules. Skull roentgenogram and computerized tomogram scan showed multiple osteolytic lesions with increased uptake in bone and gallium scans.
