H/o stroke. There is redemonstration of the bilateral ACA, MCA and PCA territory and right cerebellar with vermis strokes. In comparison with prior brain MRI, there appears more mass effect, causing effacement of the fourth, third and left lateral ventricles and prepontine cistern. There are also enlargement of the right lateral ventricle and more midline shift to the right. Postoperative change of a frontal craniotomy and residual suprasellar and sellar mass are re-identified. The right subdural fluid collection is not visualized. No new hemorrhage is detected.
1. Bilateral ACA, MCA and PCA territory and right cerebellar with vermis strokes with increased mass effect. 2. Interval development of hydrocephalus of the right lateral ventricle. 3. Stable postoperative change of a frontal craniotomy.
