MRI images for the case 9. A. The T1W image shows there is an irregular large patchy area with hypointensity in the right parietal lobe including white matter, gray-white matter junction, and gray mater areas. B. The T2W image shows there is an irregular large patchy area with hypointensity (Black arrow) in the right parietal lobe including white matter, gray-white matter junction, and gray mater areas. Large patchy areas of the edema was seen in the area surrounding the lesion (White arrow). The edema on a T1W image appears as low signal but on a T2W image is high signal. C. The enhanced T1W image shows a ring-enhanced lesion. D. is the microscopic appearance of post surgery of the cerebral sparganosis (HE × 200). Pathological diagnosis proved cavitations due to fibroplasias of cerebral tissue with degenerated larva, partly necrotized substances and calcification. There was fibrosis of surrounding the brain tissue with several granulomas and infiltration of inflammatory cells and gliosis. These findings highly suggested granulomas due to parasitic infection.
