Abstract

We performed a double-phase Tc-99m-Sestamibi SPECT study on a patient who presented with a mass located at the skull base. The results were compared with double-phase T1-201 SPECT study. Early phase (30 min) SPECT images of both radiopharmaceuticals demonstrated increased radiotracer uptake in the region of the tumor. However, late images (180 min) revealed rapid wash-out of Tc-99m-SestaMIBI from the tumor, suggestive of a benign vascular tumor, while T1-201 images showed slower wash-out. Tc-99m-SestaMIBI SPECT findings were also confirmed by carotid angiography and biopsy, while a contemporaneous MRI scan was inconclusive in differentiating benign from malignant tumor. Initial and one-year follow-up whole body CT scans were negative for any metastatic sites, supporting the diagnosis of benign glomus jugulare tumor.
