Publication Espondilodiscitis por Haemophilus parainfluenzae: Un reporte de caso(2022) Yurac, Ratko; Santorcuato, Macarena; Quinteros, Guisela; Zamorano, Juan; Marré, BartoloméIntroduction Haemophilus parainfluenzae (HP) is a gram-negative coccobacillus andan opportunistic pathogen. It is rarely associated with spinal- and musculoskeletal-site infections, and very little reported in the literature. Case Presentation An otherwise healthy, 45-year-old woman who presented with a two-week history of progressive low back pain, fever, coryza and nasal congestion, was found to have intervertebral discitis caused by HP, confirmed by two positive blood cultures and progressive lumbar spine magnetic resonance imaging (MRI) findings. The MRI findings were atypical, consisting of a psoas abscess and small anterior epidural and intraspinal fluid collections associated with spondylodiscitis. The initial diagnosis was delayed because the initial MRI failed to reveal findings suggestive of an infectious process. The treatment consisted of a long course of intravenous followed by oral antibiotics, ultimately yielding a good clinical response. Discussion and Conclusion Haemophilus parainfluenzae is a very rare pathogen inspondylodiscitis. Nonetheless, it should be considered, especially in patients presenting with low back pain and fever and/or gram negative bacteremia. Theinitial work-up should include contrast-enhanced MRI of the spine. Although rare, spondylodiscitis and a psoas abscess can present concomitantly. Prolonged antibiotics are the mainstay of treatment.
