99mTc-Sulfur Colloid SPECT/CT in Diagnosis of Splenogonadal Fusion

Le résumé fourni par la source

A congenital abnormal connection between an accessory spleen and a gonad is called splenogonadal fusion. The parent of a 3-y-old boy brought him to King Saud Medical City because he had left scrotal swelling that had begun 1 y previously. 99mTc-sulfur colloid (SC) imaging has superior sensitivity and specificity in targeting the liver, spleen, and bone marrow, in that these are the only organs that 99mTc-SC can visualize. Furthermore, if these tissues appear anywhere other than their usual locations, such as in the case of an accessory spleen, 99mTc-SC imaging can identify them even without biopsy or—in the case of splenogonadal fusion—orchiectomy. In the current case, the patient underwent laparoscopy, the masses were removed, and orchiectomy was avoided. Histopathologic examination confirmed normal splenic tissue, matching the imaging results.
