Sarcoidosis Involving the Spinal Dura

ABSTRACT

Neurosarcoidosis without systemic manifestation is vary unusual condition. Solitary lesion in the spinal dura is exceptional. The diagnosis of the neurosarcoidosis is very difficult, because the efficacy of Kveim test is low in neurosarcoidosis. The histologic examination is considered as confirmative diagnostic tool. The authors reported a case of neurosarcoidosis involving the dura of the cervical spine, in a fifty-nine year old female who had suffered from mid-back pain for six months and paraparesis for two weeks. There was a dumbbell shaped mass in the D4-5 dura. It showed tan gray color with rubbery consistency. With histological examination, it revealed diffuse non-caseating granuloma. Occasionally asteroid bodies were observed within the cytoplasm of the multinucleated giant cells. After operation, she was treated with steroid, and she has been well about nine month period.
