Hemophilus aphrophilus meningitis followed by vertebral osteomyelitis and suppurative psoas abscess.

Hemophilus aphrophilus is an uncommon pathogen in man. It has rarely been reported as a cause of meningitis, exclusively in boys three years or younger. Osteomyelitis due to this organism is also rare. H. aphrophilus was responsible for meningitis, probable thoracic empyema, and ultimately vertebral osteomyelitis and suppurative psoas abscess formation in a woman following metrizamide myelography. The patient responded well to antibiotic treatment and surgical drainage. The organism was sensitive not only to chloramphenicol but also to newer cephalosporin antibiotics.
