T2-weighted (A) and you may gradient-mirror (T2*) (B) MR images from someone which have SS have indicated superiority of gradient-mirror method when you look at the finding the brand new trait T2 hypointensity, found right here over the Sylvian and you can interhemispheric fissures.

An excellent and you will B, Sagittal (A) and axial (B) T2-weighted spinal-cord MR images let you know hemosiderin deposition along (A) and you can around (B) the fresh wire surface. Note relevant really serious wire atrophy (A) (dotted arrow). C and D, Axial T2-weighted MR photo from the number of the brand new cauda equina of people that have SS show peripheralization (C) and you can clumping (D) of your courage roots because of arachnoiditis. E, A keen axial slashed at lumbar membership with the a good CT myelogram out-of the patient which have SS reveals clumping out of nerve origins regarding the new cauda equina on account of arachnoiditis. F, T2-weighted sagittal MR image of brand new lumbosacral area out of an individual having SS suggests a lesion which had been suspected of being good you can way to obtain the new persistent hemorrhaging. An excellent biopsy is did, and you will bloodstream products and stringy cells were sensed. Low siderosis: connections and you may therapeutic ramifications.

A good, Axial T2-weighted back MR image away from a patient having SS reveals a great remaining T12 pseudomeningocele. B, Axial T2-adjusted brain MR photo away from someone with SS suggests an effective posterior fossa water-occupied collection. C1 and C2, Sagittal (C1) and you will axial (C2) T2-adjusted cervical MR photos out-of a patient having SS reveal a good best C7 pseudomeningocele (exact same diligent because you to revealed for the Fig 10B). D, Sagittal T2-adjusted spine MR image out-of a patient which have SS shows a keen intrasacral meningocele. E, Axial T2-weighted thoracic cable MR photo reveals a fluid-filled collection anterior toward spinal cord. F, Sagittal T2-weighted MR image suggests a great longitudinally thorough water collection ventral in order to this new wire. The dotted arrow reveals tethering of your cord during the T9. Grams, Sagittal T2-weighted back MR image from someone having SS reveals numerous intraspinal water-filled loculations.

T2-weighted MR imaging reveals a rim away from hypointensity within the cerebellum (Fig 1A, -B) and brain stalk (Fig 1C?E). Brand new marginal T2 hypointensity may cover the fresh Sylvian fissure (Fig 1F), interhemispheric fissure (Fig 1G), and you may cortical sulci (Fig 1H). This new superior vermis, quadrigeminal dish, and you will basal emotional facial skin is actually preferentially influenced by new marginal T2 hypointensity. Hemosiderin deposition may also be seen along cranial nerves II, V, VII, and you may VIII (Fig 1I). The latest peripheral neurological system isn’t doing work in SS. Discover a-sharp cutoff from the spine origins and you can cranial nervousness in the junction within peripheral Schwann cell sector and you will the fresh central glial segment. 41 Cerebellar atrophy is sometimes introduce, and the superior vermis and you can prior cerebellar hemispheres are preferentially on it by the atrophy (Fig 1J). The new gliosis and you can neuronal losses for the hemosiderin deposition get effect inside increased signal power throughout the adjacent cerebellar cells. twenty two,twenty six Instead, it could be only an evident increase considering the overlying hypointensity. Hardly, an effective hyperintense rim is generally seen towards T2-weighted imaging. 26 It on account of methemoglobin and represents a recently available episode of subarachnoid hemorrhage.
