bone-island
A 45-year-old woman undergoes an abdominal CT for investigation of renal colic. Incidentally, a 12mm dense sclerotic lesion is identified within the left iliac wing. The lesion has a characteristic appearance with radiating spicules extending into the surrounding trabecular bone, giving a "thorny" or "brush-like" border. The kidney stone is confirmed and treated. **What is the MOST appropriate management for this bone lesion?**
Mark each as TRUE or FALSE
Urgent bone biopsy to exclude osteoblastic metastasis
Whole-body bone scintigraphy to assess for multiple lesions
No further investigation required; this is a classic bone island (enostosis)
MRI of the pelvis with gadolinium to assess for soft tissue extension
PET-CT to exclude metabolically active malignancy
