Male, 56 years old, with toxoplasmosis, follow-up examination. Currently asymptomatic. A lobulated lesion with diffusion restriction and moderate local edema is unchanged in the right occipital lobe. An oval lesion in the right corona radiata with ring restricted diffusion demonstrates slightly reduced FLAIR signal abnormality. Numerous additional small foci of FLAIR hyperintensity are redemonstrated in both cerebral hemispheres without significant interval change. As on the prior examinations, several of the intracranial lesions are associated with susceptibility effect but this is unchanged.No new lesions are seen. No significant generalized mass effect is detected. There are no abnormal extra-axial collections. The ventricular system is stable in size. Redemonstrated is ill-defined non-specific T2 hyperintense signal in the posterior medulla and pons showing no interval change. Opacification of the left ethmoid air cells and perhaps the adjacent nasal cavity is unchanged.
1.A lesion in the right occipital lobe which induces moderate local edema has not significantly changed.2.A small lesion in the right corona radiata has become smaller. Numerous additional scattered nonspecific lesions show no significant interval change. No new lesions are detected.3.Stable soft tissue opacification of the left ethmoid air cells.
