Bochdalek hernia presenting with initial local fat infiltration of the thoracic cavity in a leukemic child

View Article: PubMed Central - PubMed

ABSTRACT

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 cavity on computed tomography scan may indicate a potential diaphragmatic hernia.

(B-D) The soft tissue (white arrows) posterior to the diaphragm with average computed tomography (CT) value between −61 Hu and −91 Hu, consistent with fat tissue, diagnosed as local fat infiltration of the left thoracic cavity.

Mentions: Sonography showed the maximum oblique diameter of the right hepatic lobe as 13.8 cm and spleen thickness as 4.2 cm; both results suggested a finding of hepatosplenomegaly. Chest CT scan demonstrated patchy density of the left lower lobe in lung window, which was diagnosed as focal infection (Fig. 1A). Viewed with mediastinal settings, regional low density was noted with a median CT value of −90 Hounsfield units in the left thoracic cavity, indicating local fat infiltration, but no explicit diaphragmatic opening was depicted (Fig. 1B,C, and D).
