Parotid liposubstitution is a fatty degeneration of the parotid gland, sometimes increasing in volume.
Parotid liposubstitution is physiological with age but which may be associated with local or systemic conditions that include:
hypertriglyceridemia may be associated with fat infiltration without inflammatory activity
adnexectomy for decreased ovarian hormones
Sjögren's syndrome, for adipose degeneration and lymphocytic infiltration
human immunodeficiency virus with fat infiltration, lymphocytic aggregates, lymphoepithelial cysts or lymphadenopathy
alcoholics and diabetics
aging with an increase in lipids and degeneration of secretory granules
Patients are asymptomatic or present with xerostomia.
MRI the fat deposits on the parotids:
T1 and T2: high signal
T1 and T2 fat suppression: low signal
T1 C+ (Gd): no significant enhancement
Treatment and prognosis
Therapy only if associated with systemic pathologies.
