title: Neuroblastoma masquerading as a retroperitoneal Salmonella abscess.
abstract: Symptomatic Salmonella infections usually manifest as self-limited gastrointestinal distress. Patients with chronic systemic illnesses or those who are immunosuppressed may rarely present with Salmonella infection as distant suppurative abscesses. We present a previously healthy Armenian boy who came to medical attention with abdominal pain, fever, and anemia. Abdominal computed tomography (CT) scan showed a cystic suprarenal mass that was surgically explored and found to be a retroperitoneal Salmonella abscess. Postoperative CT scan showed resolving inflammation. A 6-month follow-up CT showed a large suprarenal tumor, which at exploration was found to be neuroblastoma. To our knowledge, Salmonella has never been reported presenting as a solitary retroperitoneal abscess, and neuroblastoma has not been described presenting as a Salmonella abscess. The patient is also unusual because the abscess contained a species unusual for suppurative salmonellosis.
