title: [A case of painful defect of unknown origin of the pediatric patella].
abstract: An uncertain history of potential trauma versus possible developmental variants and disorders in childhood may cause differential diagnostic problems in pediatric radiology. We report the case of a 12-year old boy with an unclear unilateral defect of the patella and long-persisting complaints in his knee. The plain radiological and MRI morphology of this lesion are described and possible differential diagnoses are discussed.
