If neoplasia is suspected but initial radiographs lack aggressive features, what is recommended to detect progression?

• A. Repeat radiographs after about 10 days
• B. CT findings alone
• C. MRI
• D. Ultrasound

Answer: (A)

Early bone neoplasia can be radiographically quiet, so short-interval imaging is often the best way to catch progression. Repeating radiographs after about 10 days gives enough time for subtle changes to become evident—such as new lytic areas, cortical destruction, periosteal reaction, or soft tissue swelling—that indicate the lesion is evolving. This approach is practical, cost-effective, and readily available, and it helps guide whether to pursue more advanced imaging or biopsy. Advanced modalities like CT or MRI offer more detail but aren’t the most efficient first step for detecting early progression when initial films are non-aggressive, and ultrasound has limited utility for bone lesions.
