Case presentation

A 52 year old gentleman presents with a 6 month history of pain in his left lower side and left groin. He was admitted to hospital with pain and malaise.

Radiological findings:
Plain radiographs reveal a large osteolytic lesion in the left ilium directly superior to the left acetabulum. It measures approximately 5.4cm in its largest dimension. The lesion is ovoid in shape and relatively well-circumscribed. There is no surrounding sclerosis or periosteal reaction. The lesion is not expansile. CT of the pelvis show multiple smaller osteolytic lesions throughout the pelvis bilaterally. The left-sided lesion has not completely eroded the cortex. There are no fractures or protrusio femoris. There is a smaller osteolytic lesion in the right ilium but not in contact with the acetabulum on that side.

Blood tests: Hypercalcaemia, hyperuricaemia and reduced eGFR.
