摘要

目的：分析腮腺腺泡细胞癌（AciCCs）与Warthin瘤（WTs）、多形性腺瘤（PAs）、基底细胞腺瘤（bca）、黏液表皮样癌（MECs）的临床及CT特征。研究设计：这项回顾性研究包括359例原发性腮腺肿瘤患者，所有患者在治疗前都接受了CT增强扫描。临床表现，治疗方案和随访资料也进行了回顾。结果：共纳入AciCCs 63例，WTs 74例，PAs 70例，bca88例，MECs 64例。在AciCC患者中，71.4%（45/63）表现为无痛性肿块。在CT上，AciCCs被观察到为定义明确（12/63），部分不明确（26/63）或定义不明确（25/63）的肿瘤，没有特定的位置偏好。与PAs相比，AciCCs在动脉期表现出更高的CT衰减，但低于bca、mec和WTs。85.7%（54/63）的患者行腮腺部分切除术，25例患者行间质近距离放射治疗。复发率低，仅1例（1.6%）复发。结论：AciCC可根据肿瘤大小、衰减模式等增强CT特征与其他常见腮腺肿瘤鉴别。

Clinical and radiological features of acinic cell carcinoma in the parotid gland: a contrast-enhanced CT evaluation

Objective

To analyze the clinical and computed tomography (CT) features of acinic cell carcinomas (AciCCs) of the parotid gland in comparison with Warthin tumors (WTs), pleomorphic adenomas (PAs), basal cell adenomas (BCAs), and mucoepidermoid carcinomas (MECs).

Study Design

This retrospective study included 359 patients with primary parotid gland tumors, all of whom underwent contrast-enhanced CT scans prior to treatment. Clinical manifestations, treatment regimens, and follow-up information were also reviewed.

Results

A total of 63 AciCCs, 74 WTs, 70 PAs, 88 BCAs, and 64 MECs were included. Among AciCC patients, 71.4% (45/63) presented with a painless mass. On CT, AciCCs were observed as well-defined (12/63), partially ill-defined (26/63), or ill-defined (25/63) neoplasms, with no specific location predilection. AciCCs exhibited higher CT attenuation in the arterial phase compared to PAs but lower than that of BCAs, MECs, and WTs. Partial parotidectomy was performed in 85.7% (54/63) of cases, and interstitial brachytherapy with I¹³¹ was administered to 25 patients. The recurrence rate was low, with only 1 case of recurrence (1.6%).

Conclusions

AciCC can be distinguished from other common parotid tumors based on its contrast-enhanced CT features, such as tumor size and attenuation patterns.

期刊介绍： Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology is required reading for anyone in the fields of oral surgery, oral medicine, oral pathology, oral radiology or advanced general practice dentistry. It is the only major dental journal that provides a practical and complete overview of the medical and surgical techniques of dental practice in four areas. Topics covered include such current issues as dental implants, treatment of HIV-infected patients, and evaluation and treatment of TMJ disorders. The official publication for nine societies, the Journal is recommended for initial purchase in the Brandon Hill study, Selected List of Books and Journals for the Small Medical Library.
