Abstract
A 32-year-old man was treated in our unit (Tuen Mun Hospital, Hong Kong, China), for a chest wall tumor. He had initially presented to another center because of right-sided chest pain. Computed tomography detected a chest wall mass with invasion to his ribs. He was given a diagnosis of immunoglobulin G4-related disease and was started on immunosuppression. The mass regressed, but his symptoms progressed. Open rib biopsy was performed at our center. Culture grew Salmonella group D, and a diagnosis of chronic osteomyelitis of the rib was made. He completed a course of antibiotics and currently follows up at our outpatient clinic and is symptom free.
