摘要: 背景与目的:腺样囊性癌(adenoid cystic carcinoma,ACC)是起源于涎腺组织的一种少见恶性肿瘤,该研究旨在探讨磁共振成像(magnetic resonance imaging,MRI)在头颈部ACC中的应用价值。方法:回顾性分析上海市质子重离子医院2015年5月—2017年9月收治的26例(19例原发,7例复发)经手术病理证实的头颈部ACC患者的临床和MRI资料。结果:26例肿瘤中,位于鼻咽8例,腭6例,鼻腔4例,上颌窦3例,颌下腺和舌各2例,喉1例。23例肿瘤形态不规则,边界不清;其余3例呈类圆形,边界较清。所有病灶与肌肉相比在T1WI上呈等信号,在T2WI上呈高或稍高信号,增强后可见明显强化。17例侵犯神经中,累及翼腭窝16例,累及海绵窦10例,卵圆孔8例,圆孔4例,眶上裂2例,视神经管2例,舌下神经管2例,翼管1例。21例侵犯骨质,11例侵犯颅内。结论:MRI能够清晰显示ACC的肿瘤范围及神经受累情况,可为临床治疗提供更多信息。

Abstract: Background and purpose: Adenoid cystic carcinoma (ACC) is a rare malignant tumor arising from salivary glands. This study aimed to evaluate the value of magnetic resonance imaging (MRI) in diagnosing ACC of the head and neck. Methods: The clinical and MRI data of 26 patients treated in Shanghai Proton and Heavy Ion Center from May 2015 to September 2017 with ACC of the head and neck (primary 19 cases, recurrent 7 cases) confirmed by histopathology were analyzed retrospectively. Results: Tumors were located in the nasopharynx (8 cases), the palate (6 cases), nasal cavity (4 cases), maxillary sinus (3 cases), submandibular gland (2 cases), the tongue (2 cases) and the larynx (1 cases). Twenty-three lesions were irregular in shape and ill defined, and 3 lesions were oval and well defined. Compared with muscle signal intensity on MRI, all tumors demonstrated isointensity on T1WI, high or slightly high intensity on T2WI, and avid enhancement after contrast administration. We found perineural spread in 17 cases (pterygopalatine fossa involved in 16 cases, cavernous sinus in 10 cases, foramen ovale in 8 cases, foramen rotundum in 4 cases, superior orbital fissure in 2 cases, optic canal in 2 cases, hypoglossal canal in 2 cases, pterygoid canal in 1 case), bone abnormality in 21 cases, and intracranial extension in 11 cases. Conclusion: MRI could display the extent and perineural spread of ACC in the head and neck, providing more information for treatment plan.
