What is the recommended initial approach for suspected sialoliths?

• A. Screening with panoramic radiograph; refer for CT if localization is needed
• B. Immediate MRI
• C. Only ultrasound is sufficient
• D. No imaging needed

Answer: (A)

When sialoliths are suspected, the first step is a screening panoramic radiograph. This widely available, quick image can detect many radiopaque stones in the salivary ducts, providing an initial view of the stone’s presence and rough location. If the stone isn’t localized well on that film or precise three‑dimensional positioning is needed to plan treatment, a CT scan offers detailed cross‑sectional localization, guiding approaches such as sialendoscopy or surgical removal. MRI isn’t the best starting choice for calcifications, and relying on ultrasound alone can miss stones or be operator dependent. In short, start with a panoramic radiograph, and use CT for localization if needed.
