一名54岁的妇女出现食管病变升高。计算机断层扫描（CT）和磁共振成像显示胰头肿块。内窥镜超声（EUS）显示明确的，圆形,低回声肿块,这被认为是淋巴结肿大。对食管和胰头上方的肿块进行了EUS引导的细针穿刺活检（FNAB）。经病理证实的上皮细胞和多核巨细胞T-SPOT阳性。临床上,怀疑有结核性淋巴结炎和食管结核，抗结核治疗的成功治疗产生了良好的反应。我们的发现表明EUS-FNAB可用于诊断食管结核。
A 54-year-old woman presented with an elevated esophageal lesion. Computed tomography (CT) and magnetic resonance imaging revealed a mass in the pancreatic head. Endoscopic ultrasound (EUS) showed a well-defined, round, hypoechoic mass, which was considered lymph node enlargement. An EUS-guided fine-needle aspiration biopsy (FNAB) was performed on the esophagus and the mass above the pancreatic head. The pathologically confirmed epithelial cells and multinucleated giant cells were positive for T-SPOT. Clinically, tuberculous lymphadenitis and esophageal tuberculosis were suspected, with successful treatment with anti-tuberculosis therapy resulting in a good response. Our findings suggest that an EUS-FNAB is useful for diagnosing esophageal tuberculosis.
