Abstract

Rationale: Adenoid cystic carcinoma is a rare malignant tumor of the salivary glands, with few reports of metastasis to the liver in the literature. We present a case where an isolated hepatic lesion of adenoid cystic carcinoma was identified using 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT).

Patient concerns: A 76-year-old male experienced abdominal pain and underwent an enhanced CT scan and magnetic resonance imaging, which revealed a liver mass. Subsequent 18F-FDG PET/CT identified hypermetabolic lesions in both the left and right lobes of the liver, suggesting malignancy, with no other abnormalities detected.

Diagnoses: A liver biopsy confirmed the diagnosis of adenoid cystic carcinoma.

Interventions: No intervention.

Outcomes: Following confirmation of the diagnosis, the patient chose to discontinue treatment and was discharged.

Lessons: Hepatic metastasis from adenoid cystic carcinoma may be detected before the identification of the primary lesion. 18F-FDG PET/CT plays a critical role in differentiating benign from malignant liver tumors, selecting potential biopsy sites, and assessing the extent of metastatic disease.

通过 PET/CT 鉴定未显示的腺样囊性癌的肝转移：病例报告。

理由：腺样囊性癌是一种罕见的唾液腺恶性肿瘤：腺样囊性癌是一种罕见的唾液腺恶性肿瘤，很少有文献报道腺样囊性癌转移至肝脏。我们介绍了一例利用 18F- 氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（18F-FDG PET/CT）发现腺样囊性癌孤立性肝病变的病例：一名 76 岁的男性出现腹痛，接受了增强 CT 扫描和磁共振成像，结果显示肝脏肿块。随后的 18F-FDG PET/CT 发现肝脏左叶和右叶都有高代谢病变，提示为恶性肿瘤，未发现其他异常：肝活检确诊为腺样囊性癌：干预措施：无干预措施：确诊后，患者选择停止治疗并出院：启示：腺样囊性癌的肝转移可能在确定原发病灶之前就被发现。18F-FDG PET/CT 在区分良性和恶性肝肿瘤、选择潜在活检部位以及评估转移性疾病的程度方面发挥着至关重要的作用。
