An unusual cause of chest pain

Case report :We present the case of a 27year-old male who went to the Emergency Room for the acute onset of chest pain irradiated to left flank and fever by 2 days. An abdominal computed tomography (CT) scan, performed for the suspicion of a kidney stone, showed a left basal pulmonary opacity. The patient was admitted to our department for suspected community-acquired pneumonia (CAP) but, a few days later, a chest CT scan with intravenous contrast revealed a thoracic congenital malformation: intralobar pulmonary sequestration. The pulmonary lesion was resected and the histopathological examination of the lesion showed the features of pulmonary sequestration. Conclusions :Pulmonary sequestration is a rare congenital malformation that is usually diagnosed in the Pediatric age. We report here an unusual case of intralobar pulmonary sequestration in an adult mimicking a CAP and a lung cancer.
