ABSTRACT
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.

ABSTRACT: A 77-year-old man with a case of hyperthyroidism with high parathyroid hormone (41 pmol/L), low vitamin D, and normal thyroid-stimulating hormone. The SPECT/CT fused images confirmed the evidence of retrotracheal hyperdense mass approximately 1.0 cm of diameter below the lower pole of the right thyroid lobe with increased uptake, highly suggestive of typical parathyroid adenoma. The most significant point is that there was an incidental finding: high focal uptake in the sellar/suprasellar region corresponding to heterogenous soft tissue lesion suspicious for pituitary adenoma. According to the previous scans, nuclear medicine, CT scan, and the MRI scan indicated pituitary adenoma.
