 Hemorrhage is redemonstrated in the right lateral ventricle and in the right thalamus appearing similar in quantity and distribution to prior exams. The right lateral ventricle remains widened. There are T2/FLAIR hyperintensities in the corona radiata, representing chronic ischemic small vessel disease. No parenchymal restricted diffusion is seen. There is a ventriculostomy track coursing from a left frontal approach into the left ventricle, reflecting the previously removed ventriculostomy tube. There is a volume loss affecting the right basal ganglia with hemosiderin staining, likely indicating a prior hemorrhagic insult. There is punctate susceptibility signal along the left lateral ventricle and the ventriculostomy track, representing old blood products. There is no definite abnormal enhancement.Ventricular size is stable with no midline shift. Basal cisterns are patent.
1. As on the previous CT there is redemonstration hemorrhage in the right lateral ventricle and in the right thalamus.2. No definite evidence of any mass or enhancing lesion. Please note that the presence of blood may obscure a small or subtle enhancing lesion.3. Nonspecific T2/FLAIR hyperintensities in the corona radiata, suggestive of chronic ischemic small vessel disease.4. Mild volume loss and hemosiderin staining affecting the right basal ganglia suggests a prior hemorrhagic insult in this location.
