A 60-year-old man with colonic diffuse large B-cell lymphoma was referred for FDG PET/CT for initial staging. He was suspected of enterovesical fistula. After oral administration, large amounts of contrast agents accumulated in the bowel lumen and leaked into the bladder through a well-marked fistulous tract. Corresponding to the fistula, a linear pattern of FDG uptake extended from the bladder into the colonic lumen, and the measured SUV max inside the lesion was as high as that of the urinary bladder. Cystography confirmed the presence of the enterovesical fistula.
一位 60 岁男性，患有结肠弥漫性大 B 细胞淋巴瘤，为进行初始分期而行 FDG PET/CT 检查。他被怀疑患有肠膀胱瘘。口服造影剂后，大量造影剂积聚在肠腔内，并通过明显的瘘管漏入膀胱。与瘘管相对应，FDG 摄取的线性模式从膀胱延伸至结肠腔，病变内的 SUVmax 测量值与膀胱相当。膀胱造影证实存在肠膀胱瘘。
