Intervention
Biopsy often is needed to diagnose Paget sarcoma. In such cases, CT typically is the modality of choice for guidance.
Medicolegal Pitfalls
- Secondary sarcomas may occur in approximately 1% of patients with Paget disease. Some argue that early diagnosis of these lesions may not confer significant benefit to patients because of the poor prognosis associated with the lesions. However, lesions discovered in the extremities may be resected with positive results, and delayed diagnosis may affect the prognosis for cure or prolonged survival. Short-term interval follow-up and/or cross-sectional imaging may prevent diagnostic errors and initiate prompt attention to a newly developing lesion.
