Pelvic osteomyelitis due to Haemophilus influenzae type B in a Down syndrome child.

Pelvic osteomyelitis in children is uncommon, and Staphylococcus aureus is the most commonly encountered organism. The diagnosis of pelvic osteomyelitis is usually delayed. With an early diagnosis and commencement of appropriate anti-microbial therapy, the outcome is usually favorable. We present a 14-month-old girl with Down syndrome and right iliac bone osteomyelitis secondary to Haemophilus influenzae type B. To our knowledge, the association of the elements of pelvic osteomyelitis, Down syndrome and K influenzae has not been previously reported.
