Long‐term outcome of infectious sacroiliitis due to Pasteurella multocida in a dog

Abstract

AbstractA 6‐month‐old, male German shepherd dog was presented with a 2‐week history of left pelvic limb lameness. Physical examination revealed severe left pelvic limb lameness, lumbosacral and left pelvic limb pain. Magnetic resonance imaging showed heterogeneous T2‐weighted hyperintensity, T1‐weighted hypointense with marked contrast enhancement in the left sacroiliac joint, consistent with unilateral sacroiliitis. Computed tomography was used to perform image‐guided arthrocentesis and also revealed an irregular left sacroiliac joint. Infectious sacroiliitis, caused by Pasteurella multocida, was confirmed by culture of the synovial fluid of the sacroiliac joint. Infectious sacroiliitis should be considered as a differential diagnosis for young dogs presented with pelvic limb lameness and pain.
