Obstructed parotid duct: MR sialogram

Case contributed by Dr Chris O'Donnell


Long standing left facial pain, worse with eating meals

Patient Data

Age: 35
Gender: Male
Modality: MRI

Dilated left parotid duct from the gland extending up to the left cheek where there is a tapered narrowing. Note the asymmetry when compared with the right (arrows). Note also the dilated accessory duct entering the main duct (best seen on the sagittal imaging)

Modality: Ultrasound

US confirms the MRI findings and shows minor increase in vascularity in the gland parenchyma.  No intra-luminal calculus at the distal end of the duct in the cheek.

Case Discussion

Catheter sialography is fiddly and uncomfortable for the patient.  MR sialography is a useful alternative especially if the ducts are dilated
