CT scans of our patient before and after imatinib rechallenge. (A,B) Recurrent tumors (nodules) can be seen in the peritoneum of our patient, who had received prior adjuvant imatinib treatment. (C,D) After one month of rechallenge with imatinib, our patient demonstrated a partial response to imatinib treatment, with the nodule sizes decreasing by 43%.
