Sialocele

Dr Henry Knipe and Dr Yuranga Weerakkody et al.

Sialoceles are cystic spaces (usually saliva containing) arising within a salivary gland.

They are essentially post- traumatic or iatrogenic in nature. The proposed mechanism includes laceration of the salivary glad duct or ductal stenosis with subsequent dilatation.

Patients are often asymptomatic soft and may present with mobile swelling involving the affected salivary gland.

May show a hypoehoic-anechoic cyst within the affected salivary gland.

Axial T2 weighted and CISS sequences have been show to be useful to show the location (intra/extraparenchymal, superficial/deep lobe) of the cyst and its relation to muscles and vessels. 

Management of sialocoeles have been controversial with a range of surgical and nonsurgical treatment modalities been proposed. 

On imaging consider other cystic parotid lesions
