Emergency Radiotherapy for Spinal Cord Compression due to Bone Sarcoidosis.

Sarcoidosis is an inflammatory granulomatous disease that is systemic, but bone involvement is uncommon. A 68-year-old man was referred to our hospital complaining of right shoulder pain with numbness. Computed tomography revealed systemic lymphadenopathy and multiple bone lesions. Because malignant lymphoma with a mass lesion protruding into the vertebral canal was considered, he underwent urgent radiotherapy. Thereafter, a needle biopsy of the left parasternal node was performed and showed epithelioid granulomas, confirming a diagnosis of sarcoidosis. Since his neurologic symptoms improved, the patient was not given systemic corticosteroids. Radiotherapy may be useful for local control of bone sarcoidosis.
