Preoperative computed tomography-guided marking is useful for intraoperative identification of a tiny intraabdominal recurrent lesion of pancreatoblastoma

Preoperative computed tomography-guided marking is commonly performed for peripheral small lung lesions but rarely for abdominal tumors. This technique was useful for intraoperative identification of a tiny abdominal recurrence in a patient with ruptured pancreatoblastoma in remission. We report the case especially focusing on the technical aspect of the procedure.
