Central Nervous System Tumor-Embryonal Tumors Type With Neuroendocrine Differentiation.

Abstract

Abstract: The central nervous system (CNS) tumor with embryonal tumors type is a rare type of CNS tumor with lack of unifying genetic alterations or diagnostic markers. The CNS tumor-embryonal tumors (CETs) have limited therapeutic options with high probability of adverse events associated with conventional treatment. Identification of somatostatin receptor expression and/or prostate-specific membrane antigen expression in CET patients by using PET/CT imaging may be helpful for deciding therapeutic approaches in these patients as theranostics. We present a 56-year-old woman who complained of headache, diminution of vision, and diagnosed CET and demonstrated high SSTR expression on PET/CT imaging, indicating peptide receptor radionuclide therapy could be effective therapeutic option in this case.
