EXTRA-LOBAR INTRAABDOMINAL PULMONARY SEQUESTRATION

An ultrasonography scan detected a left upper quadrant abdominal mass in a fetus of 20 weeks gestation. The mass was confirmed by a postnata l ultrasonography scan, computerized tomography and magnetic resonance imaging prior to surgery The sonographic characteristic of this lesio n was that of a homogenous echogenic mass embedded in the left diaphra gmatic crus: which moved with respiration. Histopathological evaluatio n of the mass demonstrated alveolar and bronchial tissue, with its own visceral pleural covering corroborating the diagnosis of extra-lobar intra-abdominal pulmonary sequestration. Surgical excision is a valid recommendation because of the uncertainty of preoperative diagnosis of this uncommon malformation.
