Diagnostic puzzle with recurrent pneumonia in an adult

Recurrent pulmonary infections in adult may be due to infective cause like persistent pneumonia and pulmonary abscess or may be due to congenital anomaly like congenital pulmonary airway malformation (CPAM), bronchogenic cyst, pulmonary arteriovenous malformation, or Pulmonary sequestration[1]. Congenital pulmonary abnormalities with infection may mimic chronic infection like tuberculosis or may be pulmonary neoplasm. Here we present a young with recurrent pulmonary infection causing a diagnostic puzzle.
