title: Pneumonia presenting with lower right abdominal pain and migratory polyarthritis.
abstract: The clinical presentation of community acquired pneumonia (CAP) in adults includes mainly symptoms from the respiratory system, whereas CAP is considered as a main cause of abdominal pain in pediatric patients. We present the case of a patient, who was admitted to our hospital due to abdominal pain that deteriorated progressively and radiated to the lumbar region. The clinical examination revealed decreased breath sounds at the right lung base after 72 h, while the chest X-ray showed pneumonia of the right lung base. The blood culture isolated Streptococcus pneumoniae, and the patient received penicillin according to the results of the antibiogram. In addition, the patient developed symptoms of migratory arthritis, which resolved after 48 h. CAP should be included in the differential diagnosis of abdominal pain in adult patients. Furthermore, the hematogenous spread of S. pneumoniae may be associated with the development of migratory arthritis.
