99mTc-PSMA Uptake in Neurofibroma.

We present a 74-year-old man with a history of very high-risk prostate cancer (Gleason score: 5+4 in 11 of 14 cores) who was referred for initial staging with 99mTc-HYNIC-PSMA. The scan was reported as miT2m N2(REI, ROB) M1b(uni) M1c(skin?), PRIMARY score: 4, PSMA expression score: 1-3. We incidentally discovered increased uptake in the left skull region on whole-body images.

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 99mTc-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.
