Its longitudinal imaging evolution remains poorly characterized. Herein, we report a 51-year-old man with a GGT in the gastric antrum who underwent 6-year multimodal imaging follow-up, including CT, MRI, and serial endoscopic ultrasonography (EUS). The lesion presented as a well-circumscribed subepithelial nodule with marked and persistent enhancement on CT. It showed slightly low signal intensity on T1-weighted imaging, slightly high signal intensity on T2-weighted imaging, and mild early arterial enhancement followed by persistent marked enhancement on dynamic contrast-enhanced MRI. Over the 6-year follow-up, the lesion showed an overall increase in size and a transition from a homogeneous to a heterogeneous hypoechoic appearance on serial EUS. It was initially misdiagnosed as a gastrointestinal stromal tumor. Histopathology confirmed the diagnosis of GGT. This case highlights that GGT may exhibit characteristic yet dynamic imaging features on long-term follow-up. Recognition of these features across modalities may improve preoperative diagnostic accuracy.<\/jats:p>","DOI":"10.3389\/fonc.2026.1932357","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T05:22:05Z","timestamp":1788412925000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case
