Abstract
OBJECTIVE: The aim of this study was to characterize the ultrasound (US) and computed tomography (CT) findings of primary acinic cell carcinoma (AciCC) of the parotid gland. SUBJECTS AND METHODS: Seventy patients (70 lesions) with histopathologically proven AciCC underwent US or CT examination. The following characteristics were assessed on US images: size, shape, border, echogenicity, echotexture, internal structure, distal acoustic enhancement, and vascularity. The following characteristics were evaluated on CT images: size, shape, border, density, CT values on plain and contrast-enhanced scans, enhancement pattern, enhancement degree, and surrounding bone destruction. RESULTS: On US images, lesions were irregular, well-defined, hypoechoic, heterogeneous, and poorly vascularized. On CT images, lesions were regular and well-defined, and showed slight heterogeneous enhancement. CONCLUSION: These findings suggest that most primary AciCCs show benign features on US and CT.
