Local fat infiltration of the thoracic cavity is a rare initial presentation of Bochdalek hernia. We report a case of Bochdalek hernia in a child with leukemia that demonstrated initial local fat infiltration of the thoracic cavity on computed tomography scan and progressed to an obvious diaphragmatic hernia on subsequent follow-up. We suggest that initial local fat infiltration of the thoracic...
