Perirenal neoplastic recurrence from adenocarcinoma of the gastric cardia. After neoadjuvant chemotherapy, CT with gastric distension (oral water) and hypotonisation showed residual adenocarcinoma of the gastric cardia as focal enhancing mural thickening (short arrows) without extramural invasion. No nodal or distant metastases. Perirenal
