Partial response documented on axial (1a and 2a) and coronary (2a and 2b) computed tomography imaging of a high-risk gastric gastrointestinal stromal tumor harboring an exon 11 mutation of c-kit before (1a and 1b) and after (2a and 2b) induced by preoperative treatment with imatinib for 15 months. As a result, the patient underwent wedge resection of the stomach instead of total gastrectomy plus splenectomy. Currently, the patient receives adjuvant imatinib in the second year after surgery and remains recurrence-free.
