Case contributed by Dr Ian Bickle


Pain in right hip and unable to weight bear whilst on holiday overseas. Prior nephrectomy for RCC.

Patient Data

Age: 67
Gender: Male

The right acetabulum is largely replaced by a destructive lytic lesion with extensive cortical destruction, most pronounced on the posterior wall of the acetabulum.

Associated pathological fracture extending into the acetabular roof.

No other focal bone lesion.


The step wise approach to approaching the acetabular lesion for biopsy.

Case Discussion

Pathological acetabular fracture from in a patient with prior renal cell carcinoma (RCC).

RCC is notorious for destructive bony metastases.

Due to the fracture the patient was unable to lie prone to access the acetabular lesion for biopsy.  It was therefore performed in the lateral position.

The step wise approach to biopsy is illustrated.
