title: Agenesis of a submandibular gland with compensatory pseudotumoral hypertrophy of the contralateral gland: sonographic findings.
abstract: Agenesis of a submandibular gland with compensatory hypertrophy of the contralateral gland is an extremely rare disorder. Most reported cases of unilateral submandibular agenesis have been asymptomatic without any associated facial anomalies. We report a case of submandibular gland hypertrophy mimicking a mass that was detected incidentally. The absence of the contralateral submandibular gland and associated contralateral sublingual gland hypertrophy was confirmed by typical imaging findings.
