Female, 35 years old, with history of seizures and headache in the setting of eclampsia and PRES. The previously seen scattered areas of parenchymal signal abnormality in the bilateral frontal, parietal and occipital lobes have resolved. No residual edema or mass effect is seen. No restricted diffusion is demonstrated. Parenchymal volume is preserved with no areas of encephalomalacia.Susceptibility effect is redemonstrated within the right intraparietal sulcus, and in the right occipital lobe, similar to the prior examination. No acute intracranial hemorrhage or any abnormal extra axial fluid collection is seen. The ventricles are normal in size and morphology. Incidental note is made of a partially sella which has increased in prominence relative to the prior exam.
1.Resolution of prior findings compatible with PRES. No residual parenchymal signal abnormality is seen. No areas of parenchymal tissue loss are demonstrated.2.Susceptibility effect within the right intraparietal sulcus and in the right occipital lobe are redemonstrated similar to the prior examination. This could reflect chronic hemosiderin deposition related to the patient's prior episode of PRES.3.A partially empty sella is noted, more conspicuous than on the prior examination. This finding can reflect normal variation, though it is also seen in conditions of elevated intracranial pressure such as idiopathic intracranial hypertension.
