Standard MRI revealed a contrast-enhancing brain lesion within the left basal ganglia. 18Ffluoroethyl-L-tyrosine (18F-FET) PET showed a distinct tracer uptake (lesion-to-brain ratio [LBR]: LBRmax = 2.03, LBRmean = 1.68) with a significant larger metabolic lesion volume than contrast-enhancement in MRI, indicating cerebral glioma. Surprisingly, histopathologic analysis demonstrated central nervous system toxoplasmosis with pronounced inflammatory reaction (reactive astrogliosis, microglia activation, macrophage, and T-lymphocyte infiltration), which was associated with strong LAT1/LAT2/CD98 expression. In conclusion, inflammatory brain lesions, such as cerebral toxoplasmosis, represent a potential pitfall of 18F-FET PET mimicking a brain tumor.}, cin = {INM-3 / INM-4 / JARA-BRAIN}, ddc = {610}, cid = {I:(DE-Juel1)INM-3-20090406 / I:(DE-Juel1)INM-4-20090406 / $I:(DE-82)080010_20140620$}, pnm = {573 - Neuroimaging (POF3-573)}, pid = {G:(DE-HGF)POF3-573}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:29076908}, UT = {WOS:000415755700005}, doi = {10.1097/RLU.0000000000001873}, url = {https://juser.fz-juelich.de/record/838850}, }
