A Case of Severe Chronic Multifocal Osteomyelitis of the Skull Caused by Klebsiella pneumoniae in Mali.

Highly invasive infections caused by Klebsiella pneumonia, which includes bacteremia, liver abscess, meningitis, septic arthritis, and osteomyelitis, in not commonly seen in adult immunocompetent and immunocompromised patients. Here, we report an adult case of chronic multifocal osteomyelitis with severe cranial involvement caused by Klebsiella pneumonia. The patient has a 5-year history of orbital abscess and multiple scalp traumas. CT scan showed right temporal and periorbital osteolysis, multiple parietal osteolysis. The pus was collected twice and routine culture was positive for Klebsiella pneumoniae. Good clinical outcome was achieved with debridement and antibiotic treatment. Microbiologists and clinicians should promptly perform bacteriological cultures on biopsy specimens to facilitate diagnosis when imaging or intraoperative findings of bone infection are suspected, especially in the Mali population.
