Fusobacterium Necrophorum bacteremia involving multi-organ systems.

A 62-year-old African American man with a history of avascular necrosis (AVN) of the right hip joint presented with severe right hip pain, dyspnea, fever, tachycardia, and hypertension. Computed tomography (CT) scan showed bilateral airspace opacities with a mild tree-in-bud nodularity in the left lower lobe. Ultrasonography of the lower extremities revealed a deep venous thrombus (DVT) in the right deep veins. Blood cultures grew Fusobacterium necrophorum. CT and magnetic resonance imaging showed right hip joint destruction and septic arthritis. The patient had a complicated hospital course leading to total hip arthroplasty with antibiotic-impregnated cementing.
