Summary
Sarcoidosis affects the lungs most commonly and can present with cutaneous lesions. It can also involve the bone marrow in rare instances, often presenting with non-specific symptoms such as fever and malaise, with occasional haematological abnormalities. The authors present the case of a 41-year-old caucasian female who was diagnosed with scar sarcoidosis, but who also reported fatigue, night sweats and polyarthralgia. No haematological abnormalities or lung involvement were detected. A magnetic resonance scan of the spine, performed due to disc prolapses, demonstrated areas of bone oedema and stress response that were reported as a possible sarcoid infiltration of the bone marrow. An improvement occurred after 8 weeks, despite conservative treatment. Bone marrow involvement in sarcoidosis is rarely reported, and was an accidental finding here. Due to the non-specific presentation, cases such as this are potentially underdiagnosed and should be considered in patients with systemic symptoms, regardless of their haematological status.
