Overview
Sialolithiasis is mainly diagnosed by history and physical examination. Diagnosis can be confirmed by computed tomography, ultrasound, magnetic resonance sialography, conventional sialography. High resolution noncontrast computed tomography (CT) scanning is the study of choice for the diagnosis of sialolithisis
Diagnostic Study of Choice
Sialolithiasis is mainly diagnosed by history and physical examination. Diagnosis can be confirmed by computed tomography, ultrasound, magnetic resonance sialography, conventional sialography.
Study of choice:
Computed tomography
- High resolution noncontrast computed tomography (CT) scanning is the study of choice for the diagnosis of sialolithisis.[1]
- Most stones contain enough calcium, so they can be visible with noncontrast CT scan.
- The following results are seen in acute obstructive due to sialolithiasis after administration of contrast:
- The gland may appear enlarged
- Hyperdensity of gland with stranding
- In chronic sialolithiasis, fatty atrophy and reduction in salivary gland parenchymal volume may be seen.
The comparison table for diagnostic studies of choice for sialolithiasis
The sensitivity and specificity of CT scan and ultrasonography in a patient with sialolitiasis is given below:[2]
| Sensitivity | Specificity | |
|---|---|---|
| CT scan | 98% | 88% |
| Ultrasound | 65% | 80% |
