Bone within bone appearance

Case contributed by Dr Richard Roberts


40 day old ex full-term infant presented to the ED for evaluation of 5 days of cough.

Patient Data

Age: infant
Gender: Female

Incidental Finding: Bone within bone appearance of multiple thoracic and lumbar vertebral bodies.



Case Discussion

Patient was admitted to the hospital and was ultimately found to be RSV and Flu-positive.  Bone in bone appearance on Chest radiograph was an incidental finding on evaluation of lung fields for possible underlying etiology of cough.

This finding is nonspecific and can be a normal variant or a pathologic sign of osteopenia/osteoporosis of various etiologies.  The ex-full term infant above was otherwise an healthy infant aside from acute viral illness and the differential included normal variant vs osteopenia.
