Overview
Ultrasound may be helpful in the diagnosis of sialolithiasis. Findings on ultrasound suggestive of sialolithiasis include hyperechoic points or lines with distal acoustic shadowing and dilation of the excretory duct.
Ultrasound
- Ultrasound may be helpful in the diagnosis of sialolithiasis. Findings on ultrasound diagnostic of sialolithiasis include:[1][2][3]
- Hyperechoic points or lines with distal acoustic shadowing.
- Small stones less than 2 mm may not have shadow
- Ultrasound can detect stones that are radiolucent
- In acute obstructive cases due to sialolithiasis, ther excretory duct may be dilated.
- Hyperechoic points or lines with distal acoustic shadowing.
- Ultrasound is done with intra oral probes.
