Gastric metastasis (GM) from cervical cancer is extremely rare, and only a few cases have been reported in the English literature. Gastric-type mucinous adenocarcinomas (GAS) of the uterine cervix are rare. GAS is an aggressive cancer commonly found in advanced stages; however, GM has not been reported. This study presents a rare case of GM from GAS of the uterine cervix in a 61-year-old female and describes the radiological findings of both the GM and cervical mucinous adenocarcinoma. GM appeared as a poor enhancing submucosal mass. The cervical mucinous adenocarcinoma appeared as an infiltrating mass with poor contrast enhancement. It exhibited mildly high and low signal intensities on the diffusion-weighted image and apparent diffusion coefficient map, respectively. This case is extremely rare and challenging to diagnose; however, if cervical cancer is an human papillomavirus-independent GAS type and a submucosal lesion is found in the stomach, the possibility of metastasis with a pattern similar to our case could be considered.
宫颈癌的胃转移（GM）极为罕见，英文文献中仅报道过少数病例。子宫颈胃型黏液腺癌（GAS）很罕见。GAS是一种侵袭性癌症，常见于晚期；然而，尚未有GM的报道。本研究报告了一例61岁女性子宫颈GAS发生GM的罕见病例，并描述了GM及宫颈黏液腺癌的影像学表现。GM表现为黏膜下强化不佳的肿块。宫颈黏液腺癌表现为浸润性肿块，对比增强不佳。在扩散加权图像和表观扩散系数图上，其分别表现为轻度高信号和低信号强度。该病例极为罕见，诊断具有挑战性；然而，如果宫颈癌是与人乳头瘤病毒无关的GAS类型，且在胃中发现黏膜下病变，则可考虑有类似我们病例的转移模式的可能性。
