Abstract

Sialadenosis is characterized by asymptomatic bilateral enlargement of the parotid glands. It is uncommon, especially in children. Diagnosis and analysis of sialadenosis based on imaging modalities have been rarely reported. Here, we report a case of sialadenosis in a child with leukemia, in which the diagnosis was made based on sonography and CT findings.

  Fig. 1 Sialadenosis of parotid glands. A. High-resolution neck sonographic image using 12-5 MHz broadband linear probe shows diffusely enlarged, hyperechoic parotid gland without focal lesions. Due to enlargement of gland and posterior acoustic attenuation, deep lobe of parotid gland could not be evaluated. B. Color Doppler Sonographic image using linear probe demonstrates no evidence of increased blood flow in enlarged parotid gland. C. Contrast-enhanced neck CT. Axial CT image demonstrates diffuse enlargement of bilateral parotid glands with diffuse hypodensity (-79 - -103 HU) indicateding fat infiltration and without focal lesions. Thin capsule and internal septa of gland are noted. Thick subcutaneous tissue may be secondary to steroid treatment.
