Presentation
Bowel obstruction?
Patient Data
No bone obstruction.
Mixed lucent sclerotic expansile lesion in the left femoral neck.
Bone expansile lesion in the left ilium.
Femur imaging from several yr prior identified
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.
