摘要

一名34岁女性，有肾移植和宫颈癌病史，术前使用99mtc -植酸盐行淋巴显像检查。最初的平面图像显示多个摄取灶，随后使用SPECT/CT成像精确定位。值得注意的是，右下象限的摄取归因于移植肾的肾盂肾盂系统，这突出了异位或移植肾患者的潜在缺陷。本病例报告强调了认识到淋巴显像在复杂解剖患者中的局限性的重要性，以及混合成像在确保准确前哨淋巴结定位方面的价值。

Radiotracer Accumulation in the Pyelocaliceal System of Transplanted Kidney: A Potential Pitfall in Lymphoscintigraphy of Pelvic Malignancies.

A 34-year-old woman with a history of renal transplantation and cervical cancer underwent lymphoscintigraphy using 99m Tc-phytate before surgery. Initial planar images revealed multiple foci of uptake, which were later precisely localized using SPECT/CT imaging. Notably, uptakes in the right lower quadrant were attributed to the pyelocalyceal system of the transplanted kidney, highlighting a potential pitfall in patients with ectopic or transplanted kidneys. This case report emphasizes the importance of recognizing the limitations of lymphoscintigraphy in patients with complex anatomy and the value of hybrid imaging in ensuring accurate sentinel lymph node localization.
