Mixed sclerotic-lucent expansile lesion in the left femoral neck and proximal diaphysis. An early shepherd's crook has developed.
Case Discussion
Fibrous dysplasia incidentally identified on a plain abdominal radiograph. This was clarified and the extent elucidated on dedicated hip radiographs.
Fibrous dysplasia is the most classical and commonest condition associated with a shepherd's crook deformity.
This would make a suitable FRCR viva case.
- film edge abnormality on the abdominal film
- suggest dedicated images or review of the patient's prior imaging
- ability to assess a candidate's approach to a focal bone abnormality
- observe if the candidate recognizes a shepherds crook deformity
- explore the candidate's knowledge of a shepherd's crook deformity such as the conditions associate with this sign.
