pyomyositis with concurrent sacroiliac osteomyelitis presenting as piriformis syndrome: A rare case.

A-21-year old male admitted with fever and piriformis syndrome, typically associated with gluteal region pain radiating down the thigh, was evaluated and found to have pyomyositis involving piriformis and osteomyelitis with sacroiliac joint affection on radiological imaging. Salmonella serotype typhi was isolated from blood culture. He was treated with intravenous Ceftriaxone for 6 weeks with signs of recovery documented clinically as well as on imaging studies. Salmonella pyomyositis with osteomyelitis in an immunocompetent patient with no previous hematological or endocrine disorder makes this case an unusual presentation.
