MRI scans of the cranium. A: FLAIR sequence in the axial plane, showing foci of hyperintense signals in the vermis and the left cerebellar hemisphere, which is consistent with cerebellar hemorrhage. B: SWI sequence in the axial plane, showing marked hypointensity indicative of hemoglobin degradation products (e.g., hemosiderin), with the zebra sign (pattern of distribution among the cerebellar folia). C: T2-weighted TSE sequence in the coronal plane, confirming cerebellar hemorrhage, in the different phases of hemoglobin degradation, with alternating areas of hyperintense and hypointense signals (the zebra sign). D: T1-weighted SE sequence in the axial plane after intravenous injection of paramagnetic contrast, showing the terminus of the ventricular shunt catheter at the trigone of the right lateral ventricle. Note the small size of the lateral ventricles, together with the marked dural thickening and significant dural impregnation, as well as the hematic left frontal subdural fluid collection. This combination of findings suggests a loss of cerebrospinal fluid (intracranial hypotension syndrome).
