Extralobar pulmonary sequestration mimicking neuroblastoma.

Extralobar pulmonary sequestration is a congenital pulmonary malformation, which rarely may be present in an intra-abdominal location. We describe a 1-week-old newborn with an intra-abdominal sequestration, which presented to us as an antenatally diagnosed suprarenal mass. Intra-abdominal extralobar sequestration should also be kept in differential diagnosis in cases of masses in the suprarenal location.
