Male, 55 years old, with left-sided weakness. Assess brain lesions. Enhancing lesions are redemonstrated along the body of the right lateral ventricle, within the right ventricular atrium, occipital horn and temporal horn, and within the right cerebellum. All lesions show interval reduction in size of enhancement and degree of associated parenchymal edema. A previously noted small lesion within the left occipital lobe is no longer discretely identified. No new intracranial lesions are seen. No significant generalized mass effect is detected, though there is still mild edema related effacement of the right ventricular atrium. A few additional scattered small foci of white matter T2 hyperintensity are unchanged and nonspecific. The ventricular system is otherwise normal in size and morphology. The calvarial marrow demonstrates heterogeneous fat signal but no pathologic enhancement.
Continued interval decrease in the enhancement and associated edema related to multiple parenchymal and intraventricular lesions.
