Oversized 'Bullseye' With Central Activity TesticleA Scintigraphic Appearance of Hemorrhagic Testicular Infarct Following Traumatic Rupture of the Testicle

摘要

Tc-99m pertechnetate testicular scintigraphy and corresponding sonography were performed on a 31-year-old prisoner 9 days after he was kicked in the scrotum. Surgical exploration the following day revealed a hemorrhagic testicular infarct with rupture of the testicle. Unlike a vascular occlusive infarct of the testis secondary to torsion of the spermatic cord, the scintigraphic "bullseye" was much larger than usual and showed presence of some activity within or overlying its central zone of photopenia. Sonography revealed abnormal features highly suggestive of a traumatic testicular rupture. However, the extent of the infarct could not be as readily appreciated sonographically as with the scintigraphic images.
