研究背景：钙化纤维瘤(CFT)是一种罕见的良性间充质肿瘤，其特征是细胞学上的良性成纤维细胞产生丰富的胶原，散在的淋巴细胞、浆细胞和砂粒状或营养不良的钙化。患者关注：一名37岁的女性最初在当地医院诊断为甲状腺结节。她被转介到我们医院接受微波消融。患者身体状况良好，颈部偶尔有异物感。常规实验室检查正常。诊断：本院常规超声和超声造影怀疑病变为良性，起源于食道而不是甲状腺，经病理证实为CFT。干预：手术切除病变。结果：患者恢复良好，随访2年无复发。结论：虽然CFT影像诊断困难，但常规超声边界清楚、钙化较粗、CEUS表现为周边低强化而无中心强化，结合实时评估肿瘤与食道的关系，有助于将颈部食道CFT与其他颈部病变相鉴别。
Rationale: Calcifying fibrous tumor (CFT) is a rare benign mesenchymal tumor characterized by cytologically benign fibroblasts that produce abundant collagen with scattered lymphocytes, plasma cells, and psammomatous or dystrophic calcifications.Patient concerns: A 37 years old women was initially diagnosed thyroid nodule in local hospital. She was referred to receive microwave ablation of the nodule in our hospital. The patient was in good health with occasional foreign body sensation in the neck. Routine laboratory examination was normal.Diagnosis: The lesion was suspected benign and originating from the esophagus rather than the thyroid gland by conventional ultrasound and contrast-enhanced ultrasound in our hospital and was finally proved to be CFT by pathology.Interventions: The lesion was surgically removed.Outcomes: The patient recovered well and was followed up for 2 years without recurrence.Lessons: Although imaging diagnosis of CFT is difficult, the findings of clear border, coarse calcification on conventional ultrasound and peripheral hypoenhancement without central enhancement on contrast-enhanced ultrasound (CEUS), together with real-time evaluation of the relationship between the tumor and esophagus help to distinguish CFT of cervical esophagus from other lesions in the neck.
