Pyogenic Osteomyelitis Versus Pseudo-Osteomyelitis in Gaucher's Disease

Abstract

Presented is a young girl with Gaucher's disease who developed acute bone pain accompanied by signs of inflammation and who was felt to have possible pyogenic osteomyelitis. The lack of significant pathogenic bacterial growth on culture and the findings at orthopedic surgery led the authors to conclude that this child probably represented a case of pseudo-osteomyelitis, but the isolation of an anaerobe from the operative culture of the involved bone leaves the exact diagnosis unclear. Since this child underwent an open surgical procedure, she was treated with antibiotics to prevent the possible develop ment of chronic osteomyelitis. The anaerobic growth on culture, although strongly felt to be a contaminant, also played a role in this decision. She had an uneventful hospital course and subsequently has done well. It is suggested that great caution be taken before subjecting a patient with Gaucher's disease to orthopedic surgical procedures. If pyogenic osteomyelitis is strongly suspected, obtaining multiple blood cultures and culture by needle aspirate may be preferred over an open surgical procedure. The use of empiric anti biotic therapy without an attempt at further diagnosis is not recommended. If an orthopedic surgical procedure is necessary in a patient with Gaucher's disease, antibiotic coverage is indicated and long-term observation of the opera tive sight for drainage and/or other signs of chronic inflammatory changes is mandatory.
