A strange case of pleuritic pain in the third trimester of pregnancy

Pulmonary sequestration is an uncommon congenital malformation of the lung, generally diagnosed in childhood or adolescence, corresponding to dysplastic lung tissue not communicating with the rest of the vascular or bronchial lung system but receiving an arterial blood supply from systemic arteries. Currently, surgical resection is usually indicated to prevent or treat related symptoms or complications, although controversy exists regarding its use in asymptomatic patients and adults. We present the case of a 32-year-old pregnant woman with acute chest pain and vomiting diagnosed with intralobar sequestration at 32+2 weeks of gestation and treated with pulmonary lobectomy after giving birth by cesarean section at 33+0 weeks of gestation.
