RESUMEN
Somatostatin receptor scintigraphy is a key diagnostic tool in the initial staging and therapeutic evaluation of neuroendocrine tumors. Its specificity can be compromised by the presence of false positives. We illustrate here the case of a vertebral hemangioma detected on 99mTc-Tektrotyd scintigraphy as an incidental finding in a 34-year-old man referred for the staging of a well-differentiated neuroendocrine tumor of the ampulla of Vater (Fig. 1).
RESUMEN
A 40-year-old male patient with pulmonary tuberculosis was subjected to a perfusion lung scan to rule out pulmonary embolism. Administration of technetium-99m macroaggregated albumin through preexisting venous access resulted in multiple round hot spots in both pulmonary fields. This finding was interpreted as an artifact caused by injection through preexisting venous access.
