Normal uterine activity on a 99mTc-glucoheptonate renal scan.

Uterine radioactivity uptake has previously been reported for a variety of radionuclide agents in the presence of uterine pathological disorders, such as leiomyomata as well as uterine and cervical neoplasma and infections. Activity within the normal uterus has also been reported in Meckel's scans using 99mTc-pertechnetate, but this has not been reported for other radionuclide agents. We report a case exhibiting radioactivity uptake within a normal uterus on a 99mTc-glucoheptonate scan of a renal transplant. Awareness of the possibility of radioactivity uptake in a normal uterus is important in order to avoid potential confusion with abnormal pelvic masses or fluid accumulations.
