⁹⁹mTc-octreotide uptake in the uterus and a subserosal myoma mimicking tumoral masses.
The diagnostic usefulness of somatostatin receptor scintigraphy in the localization of tumors has been evaluated in several studies. Here, we present the case of a patient with a subserosal myoma diagnosed by (99m)Tc-labeled octreotide acetate scintigraphy. Oval and ring-shaped areas of hyperactivity in the pelvis were confirmed on MR imaging to be the uterus and a subserosal myoma. The presented case indicates that somatostatin receptors may be present in the uterus and in leiomyomas, especially in young women, and demonstrates that somatostatin may be a promising therapy for treatment of myoma. The case also demonstrates that subserosal myoma or dislocation of the uterus can result in a false-positive diagnosis, highlighting the importance of correlative imaging for accurate interpretation of the study.
