[Application of scintigraphy for preoperative localization of testis in a patient with Morris syndrome]

The paper presents the successful application for the first time in Bulgaria of the new hybrid imaging technique--tomographic scintigraphy combined with computed tomography--SPECT/CT for visualization and localization of the testis by injection of 99mTc-pertechnetate with activity of 185 MBq. The study was performed on a girl with 46XY karyotype and lack of sensitivity to androgens, known in gynecology as "testicular feminization syndrome" or Morris syndrome. Until now testicular scintigraphy has been used mainly as a very accurate technique for rapid diagnosis in cases of testicular torsion, acute epididymitis or after trauma. We found no published data in the literature concerning the use of hybrid SPECT-CT for testicular localization in Morris syndrome. Our experience is this case allows us to recommend SPECT/CT as a fast, accurate, noninvasive method with potential to be used for localization, visualization and perfusion of testicular tissue before performing surgery in cases of Morris syndrome.
