Pseudo-osteomyelitis in Gaucher's disease.

Gaucher's disease is an uncommon lipid storage disease sometimes associated with bone pain that can mimic an acute pyarthrosis or osteomyelitis. A case report with two incidences of pseudo-osteomyelitis with two-year follow-up is presented along with a literature review. Recommendations for evaluation and differentiation from a true infection are given. In general a needle biopsy for culture is preferable to any open biopsy or drainage if the diagnosis is in doubt.
