Abstract
Introduction: Ischemia in extra-lobar pulmonary sequestration is rare and mostly occurs in childhood; it is uncommon in adults but can be progressive, necessitating surgical removal.
Case presentation: A 37-year-old woman experienced sudden onset severe back pain and was initially diagnosed with pneumonia. Computed tomography revealed a 4.5 cm mass on the diaphragm and rapidly increasing pleural effusion. Emergency surgery confirmed a black mass that adhered to the diaphragm, which could be bluntly detached, but one was fixed in a cord shape that was detached by an energy device. Pathology showed significant hemorrhage and tissue destruction in extra-lobar pulmonary sequestration.
Conclusions: Extra-lobar pulmonary sequestration infarction, which develops suddenly with pain as the main complaint, is rare and mainly seen in early childhood but can also occur in adults.
