Technetium-99m (Tc)-pertechnetate can be taken up by both gastric mucosa and thyroid tissue. Ectopic gastric mucosa of upper esophagus found in thyroid scintigraphy is rare. We reported a 31-year-old woman who underwent Tc-pertechnetate thyroid static scintigraphy for abnormal ultrasound findings. A focal uptake lesion was found in her upper chest. Single photon emission computed tomography/computed tomography (SPECT/CT) imaging showed increased uptake in multiple sites of the upper esophagus without significant thickening. Eventually, gastroscopic findings revealed multiple ectopic gastric mucosa of upper esophagus.
锝-99m（Tc）高锝酸盐可被胃黏膜和甲状腺组织摄取。在甲状腺闪烁显像中发现的上食管异位胃黏膜很罕见。我们报告了一名31岁女性，因超声检查异常而接受了Tc高锝酸盐甲状腺静态闪烁显像。在她的上胸部发现了一个局灶性摄取病变。单光子发射计算机断层扫描/计算机断层扫描（SPECT/CT）成像显示上食管多个部位摄取增加，但无明显增厚。最终，胃镜检查结果显示上食管有多处异位胃黏膜。
