68Ga–Prostate-Specific Membrane Antigen PET/CT in Sinonasal Glomangiopericytoma—Exploring Theranostic Avenues!

Prostate-specific membrane antigen (PSMA) is expressed in the tumor-associated endothelial neovasculature of various nonprostatic benign and malignant neoplasms. A 25-year-old man with recurrent sinonasal glomangiopericytoma underwent whole-body 68Ga PSMA PET/CT to explore its theranostic role. There was intense PSMA uptake (SUVmax = 23.9) noted in the tumor. The uptake was more than that of the salivary glands, lacrimal glands, aorta, spleen, and the liver. Performance of PSMA PET/CT in sinonasal glomangiopericytoma opens up new frontiers concerning radiological imaging, early recurrence identification, and perhaps even radioligand therapy of residual/recurrent tumors.
