Figure 1: (a) Brain axial MRI showed long signal mixed with short signal lesion on T2 weighed image in the right frontal lobe. (b) Brain axial MRI showed enhancement of a partial focus on contrast-enhanced MRI. (c) Brain axial MRI showed long signal with short signal on T1 weighed image in the left frontal lobe. (d) Brain axial MRI showed long signal with short signal in T2 weighed image in the left frontal lobe. (e) Brain MRA was normal. (f) All major venous sinuses were patent and did not show any abnormal signals in brain MRV. (g) Brain axial MRI showed long signal mixed with short signal lesion on T1 weighed image in the left frontal lobe after craniotomy for reducing the mass effect. (h) Brain axial MRI showed long signal mixed with short signal lesion on T2 weighed image in the left frontal lobe after craniotomy for reducing the mass effect. (i-l) Histopathologic analysis was cerebral tissue was mainly necrosis (green arrow), neutrophilic granulocyte and histiocytes reaction (blue arrow), occlusion of small blood vessels (black arrow), gliacyte hyperplasia (yellow arrow). (m and n) His bilateral fundus photographies were normal
