摘要
A 69-year-old man with a history of kidney trans-plantation presented with ring-enhancing lesions in the left frontal lobe,thalamus,and right insula(Figure 1a)on magnetic resonance imaging.He was hospitalized with a diagnosis of cytomegalovirus encephalitis and had taken anti-inflammatory therapy.Follow up imaging showed a decrease in lesion size in the left frontal lobe and thal-amus;however,the right insular lesion increased in size and new ones were identified in the corpus callosum and periventricular white matter(Figure 1a).The tumor markers CA125,CYFRA21-1,CEA,PSA,and fPSA were all positive on blood testing.Because anti-inflammatory therapy was ineffective and malignant tumor could not be excluded on imaging alone,whole-body 18F-fluo-rodeoxyglucose(FDG)-positron emission tomography(PET)/computed tomography(CT)was performed(Figure 1b).
