title: Hypoplasia of the parotid gland: computed tomography sialography diagnosis.
abstract: We report two unusual cases of non-syndromic hypoplasia of the parotid gland. The hypoplastic parotid gland mimicked a preauricular parotid tumor in one case and presented as an incidental image finding in the other case. Absence of the deep lobe and isthmus of the parotid parenchyma could be determined on axial computed tomography (CT) by revealing fat tissue composition of the parotid space. The underdeveloped superficial lobe of the gland was observed on three-dimensional CT sialography.
