title: Round pneumonia in an adult.
abstract: Round pneumonia is an uncommon form of pulmonary infection usually found in children. It may resemble pulmonary neoplasm on radiographs. We present a case of round pneumonia in a 43-year-old male with a history of smoking and a family history of lung cancer. The patient was treated with antibiotics for more than two weeks, after which the infection resolved completely both clinically and radiologically. Clinicians should consider this uncommon type of pneumonia in the differential diagnosis of spherical pulmonary masses to avoid unnecessary diagnostic tests.
