Cranial Salmonella abscess with parietal bone osteomyelitis in an HIV-infected patient

Extradural abscess secondary to Salmonella enteritidis in a child following fronto-orbital facial advancement and remodeling surgery

Intracranial infections caused by Salmonella are rare. We describe the first case of a child undergoing craniofacial surgery for trigonocephaly and subsequently developing an extradural abscess secondary to likely community-acquired Salmonella enteritidis. He underwent surgical washout but returned to theater for a further 2, alongside a prolonged course of intravenous ciprofloxacin. We observed extensive anterior skull bone loss at 78 days postoperatively. At 1 year 11 months, extensive anterior skull bone remodeling had taken place, and the child is currently well.

Salmonella typhimurium epidural empyema in an HIV-infected patient

Salmonella focal intracranial infections are reported rarely. They tend to occur in immunocompromised patients. We present here a case of Salmonella typhimurium epidural empyema, with osteomyelitis of the adjacent frontal bone, in a 37-year-old human immunodeficiency virus positive man who presented with a three-day history of headache, fever, and sweats. He was treated successfully with antibiotics and surgical drainage.

Recurrent Salmonella enteritidis meningitis in a patient with AIDS

The profound impairment of cellular immunity associated with HIV infection predisposes to salmonella infections with recurrent bacteremia as a well recognized opportunistic infection in patients with AIDS. However, salmonella meningitis is extremely rare in this group of patients and only 4 cases have been reported so far. We present 1 case of recurrent Salmonella enteritidis meningitis in an AIDS patient. The infection recurred despite prolonged antimicrobial therapy. Treatment of salmonella infections in AIDS patients may be very difficult and, in some cases, lifelong maintenance therapy may be required.
