Clinical Picture

Osteopoikilosis Amara Ogbonnaya, Brittany Middleton, Tiffany Cady, Cynthia Ho

A 17-year-old boy came to our hospital with a wound infection 5 days after urological surgery. CT scan done to assess the depth of the infection showed multiple well circumscribed, ovoid, radiodense bony lesions in the pelvis and proximal femurs, consistent with the diagnosis of osteopoikilosis. Osteopoikilosis or “spotted bone disease” is a rare, benign, autosomal dominant disorder characterised by sclerotic bone lesions most commonly involving the hands, feet, pelvis, and ends of long bones.1,2 Lesions are typically found incidentally on imaging studies done for unrelated complaints.3 The symmetric distribution, lack of bone destruction, and location differentiates osteopoikilosis from metastatic disease, which tends to be seen more often in ribs, vertebral bodies, and the diaphysis of long bones.4 Bone

scintigraphy is normal in patients with osteopoikilosis.2,4 Early recognition is essential to prevent unnecessary emotional distress and invasive testing.3 No routine follow-up or studies are necessary.
