Figure 4: Sialolith in the proximal main duct of right submandibular gland. (a) Right lateral view of conventional sialogram showing cessation of contrast in the proximal main submandibular duct. (b) Sagittal MR sialogram of the right submandibular gland reveals the mild dilatation with beading of the intraglandular branches with the stone (arrow) in the proximal part of the right submandibular duct [17].
