Prenatal Diagnosis of an Extralobar Infradiaphragmatic Pulmonary Sequestration: A Case Report and Review of the Literature

Pulmonary sequestrations (PSs) are masses of non-functioning pulmonary tissue. Most PSs are situated in thoracic cavity; very rarely PSs are located below the diaphragm, particularly in the left suprarenal area. A 33-yearold primigravida underwent ultrasound scan at 24+2 weeks of gestation. Ultrasonography showed a hyperechogenic mass situated below the diaphragm. Color Doppler Flow Imaging (CDFI) showed the supplying vessels within the mass originated in the abdominal aorta. The fetus was preliminarily diagnosed with infradiaphragmatic PS. The patient opted to terminate the pregnancy. She underwent odinopoeia to deliver a male fetus who underwent postmortern examination confirmed prenatally diagnosed abnormalities.
