OBJECTIVE: @entity3330 ( @entity3330 ) are important to diagnose early to avoid progression to complete @entity174 . We set out to determine the reporting accuracy of @entity3330 . METHODS: We conducted a retrospective analysis of imaging performed between November 2010 and June 2013 to analyse the X-ray reporting of @entity3330 and to describe the key clinical considerations. Radiological reports were reviewed from the 3805 separate femoral images for search terms thought likely to identify @entity3330 . This identified 1558 @entity1 . The identified radiographs were reviewed by radiologists with reference to the 2010 American Society of Bone and Mineral Research (ASBMR) criteria. RESULTS: Within these 1558 @entity1 , 16 @entity1 met the radiological criteria for AFF according to the 2010 ASBMR task force statement of which, although all were identified as @entity174 , 15 were not reported as "atypical" by the original reporting author and none was formally classified as AFF by the original reporting author. Within the 1558 @entity1 , there were an additional 17 @entity1 labelled as having "atypical" @entity174 features originally, although only 1 @entity1 met the 2010 ASBMR task force criteria for AFF. Only 13 of 16 @entity1 had imaging of the contralateral femur, and there was a significant delay for those who were imaged (111        44 days). Furthermore, two of the @entity1 with an AFF had previous radiographs demonstrating cortical changes indicative of @entity3330 prior to formal diagnosis. CONCLUSION: Whilst @entity3330 are rare diagnoses, the compliance with published guidelines for their radiological classification is low. Advances in knowledge: We have raised awareness of the importance of recognizing @entity3330 to guide management.
