Long standing left facial pain, worse with eating meals
Patient Data
Age: 35
Gender: Male
From the case:
Obstructed parotid duct: MR sialogram
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/53933/annotated_viewer_json?iframe=true\u0026lang=us"}
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)
From the case:
Obstructed parotid duct: MR sialogram
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/53934/annotated_viewer_json?iframe=true\u0026lang=us"}
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
