The mysterious joint: Septic arthritis and acute osteomyelitis due to Fusarium species in a child with type II Chiari malformation.

Fungal bone infection due to Fusarium species is unusual. We report a case of a child who presented with septic arthritis and osteomyelitis due to Fusarium species. The lack of clinical trials and the organism's intrinsic resistance to most antifungal agents make antimicrobial management difficult. Our patient attained a favourable response to therapy with amphotericin B and voriconazole. This case report highlights a rare manifestation of joint- and bone-related Fusarium infection in a child.
