Intrarenal Splenosis Diagnosed in an Incidentally Found Left Renal Mass.

Intrarenal splenosis is very rare and its management is not well established. We present a patient in whom an enhancing left renal mass was incidentally detected on a Computerized tomographic (CT) scan, concerning for renal cell carcinoma. However, the lesion was determined to represent intrarenal splenosis, confirmed by Technetium-99m (99mTc) sulfur colloid scan and percutaneous biopsy, which revealed splenic tissue.

Somatostatin receptor scintigraphy in patients with metastatic uveal melanoma.

As uveal melanoma originates in the neural crest, we aimed to explore whether somatostatin receptor (SSTR) expression is present and plays any role in these patients. Heavily pretreated metastatic uveal melanoma patients were tested with somatostatin receptor scintigraphy (SRS). Planar images of the whole body complemented by single-photon emission computed tomography on suspected sites were acquired between 4 and 24 h after an intravenous administration of 185-222 MBq (5-6 mCi) of indium-octeotride.
