Abstract
CASE: The classic metaphyseal lesion, or corner fracture, is considered a strong indicator of nonaccidental trauma. In the present case, the parents brought their 8-month-old boy to a community hospital after he stopped crawling on the right leg. A knee radiograph demonstrated an isolated metaphyseal lesion, which prompted concern for child abuse. The patient was transferred to the nearest academic medical center; the pediatric radiology expert in child abuse determined that the lesion was a normal variant and not the result of abuse. CONCLUSION: An isolated metaphyseal lesion is not pathognomonic for child abuse, and a thoughtful differential diagnosis should be considered.
