Right-sided diaphragmatic hernia masquerading as staphylococcal pneumonia.

A 9-month-old infant who was diagnosed to have right-sided diaphragmatic hernia with no other associated anomalies, is being reported here. He had presented with cough for one month and respiratory difficulty for one-week duration and history of bilious vomiting two days prior to admission. His chest X-ray showed multiple lucent shadows in the right lower zone in A-P and lateral views, with not very well defined diaphragm on the same side. A diagnosis of staphylococcal pneumonia was considered but with clinical and radiological picture, a right-sided diaphragmatic hernia was strongly suspected which was confirmed by doing fluoroscopy and CT-scan of the chest. He underwent a successful correction of the defect. So radiological finding of pleural effusion with displacement of mediastinum to the left and the presence of bowel gas high in the right upper quadrant should alert the possibility of a right-sided Bochdalek hernia.
