摘要：

A 76-year-old man with biochemical relapse of prostate cancer underwent 68Ga-prostate-specificmembrane antigen PET/CT. Besides a local lymph node metastasis, a nodular structure inside the left orbit caudal to the optic nerve showed increased uptake. A metastasis in this location is unlikely. The subsequently performed MRI showed the structure being T1 hypointense, T2 indifferent, and strongly gadoliniumcontrast agent enhancing. Histopathologic examination after surgical removal identified the tumor as hemangiopericytoma, which rarely occurs in the orbit. Regarding the intense uptake observed, prostate-specific membrane antigen-targeting PET tracers could bear potential for staging purposes of this tumor entity.
