Diaphragmatic pulmonary sequestration.

Two cases of diaphragmatic extralobar pulmonary sequestrations are described. One of them simulated a suprarenal tumour and the other was associated with a diaphragmatic hernia. Both of them were firmly attached to the left hemidiaphragm and were partly located within it. They had an arterial supply from the abdominal aorta. Both sequestrations were treated surgically by sequesterectomy. The patients had an uneventful recovery.
