 There is hypoattenuation in the right cerebellar hemisphere corresponding to the right cerebellar infarct seen on recent MRI. Mild local mass effect with mild contour deformity of the fourth ventricle again seen. No new mass effect or evidence of hemorrhagic transformation is seen. There is a focus of hyperattenuation involving the left anterior superior frontal gyrus possibly representing a small cavernous malformation, unchanged. No surrounding edema is seen. There is an area of encephalomalacia in the right lateral occipital lobe also seen on prior MRI. Focus of likely encephalomalacia involving the anterior inferior frontal lobes also again seen.No midline shift or herniation. No hydrocephalus. Calvarium is intact. Paranasal sinuses and mastoid air cells are grossly clear.
1. Evolving right cerebellar infarct without significant change in mild local mass effect and no hemorrhagic transformation.2. Encephalomalacia involving the right occipital lobe and bilateral anterior inferior frontal lobes is again demonstrated.3. Probable small cavernous malformation involving the left anterior superior frontal gyrus is again seen.
