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.
目的
本研究旨在描述腮腺原发性腺泡细胞癌（AciCC）的超声（US）和计算机断层扫描（CT）表现。
对象与方法
70例经组织病理学证实为AciCC的患者（70个病灶）接受了US或CT检查。在US图像上评估以下特征：大小、形状、边界、回声性、回声纹理、内部结构、后方回声增强和血管分布。在CT图像上评估以下特征：大小、形状、边界、密度、平扫和增强扫描的CT值、增强模式、增强程度以及周围骨质破坏情况。
结果
在US图像上，病灶不规则、边界清晰、低回声、不均匀且血管分布少。在CT图像上，病灶规则且边界清晰，呈轻度不均匀强化。
结论
这些结果表明，大多数原发性AciCC在US和CT上表现为良性特征。
