Intramural gastric metastasis of the esophageal carcinoma, excluding the direct extension of primary neoplasm, is rare. However, intramural metastasis to the esophagus is commoner than this. These are more common in squamous cell carcinoma variant. This signifies a poor prognosis. It is due to the spread of pathology through the intramural lymphatic channels. Sometimes the metastatic lesion is more extensive in volume than the primary. This is more often diagnosed on histopathology in postoperative specimens. We share our imaging experience with surface esophageal squamous cell carcinoma with giant intramural gastric metastasis infiltrating the liver in a 39-year-old male. Due to its rarity, and secondary lesion being more extensive than the primary leads to misinterpretation and wrong diagnosis. Knowledge of this rare phenomenon can prevent misdiagnosis, fasten the imaging workup, and ultimately improve the patient's survival.
食管癌壁内胃转移，不包括原发性肿瘤的直接蔓延，较为罕见。然而，壁内转移至食管的情况比这更为常见。这些在鳞状细胞癌变体中更为常见。这预示着预后不良。这是由于病理通过壁内淋巴通道扩散所致。有时转移病灶的体积比原发灶更大。这在术后标本的组织病理学检查中更常被诊断出来。我们分享一名39岁男性患者的影像经验，该患者为食管表面鳞状细胞癌伴巨大壁内胃转移并浸润肝脏。由于其罕见性，且继发性病变比原发性病变更广泛，导致误诊和错误诊断。了解这种罕见现象可以防止误诊，加快影像检查流程，并最终提高患者的生存率。
