T2-adjusted (A) and gradient-reflect (T2*) (B) MR photo away from a patient which have SS have shown superiority of your gradient-reflect techniques inside the detecting the brand new characteristic T2 hypointensity, revealed here over the Sylvian and you can interhemispheric fissures.

An effective and you may B, Sagittal (A) and you can axial (B) T2-adjusted spinal-cord MR images let you know hemosiderin deposition along (A) and you can around (B) brand new cable skin. Notice associated serious cable atrophy (A) (dotted arrow). C and you will D, Axial T2-weighted MR pictures from the number of the latest cauda equina out of clients that have SS reveal peripheralization (C) and clumping (D) of one’s will origins on account of arachnoiditis. E, A keen axial reduce during the lumbar levels toward an excellent CT myelogram regarding an individual having SS suggests clumping out-of bravery sources from the new cauda equina because of arachnoiditis. F, T2-adjusted sagittal MR image of brand new lumbosacral city of an individual that have SS suggests a good lesion which was thought to be a beneficial you’ll be able to supply of this new chronic hemorrhaging. Good biopsy are performed, and you can blood services fibrous cells was basically thought of. Superficial siderosis: connectivity and therapeutic effects.

A good, Axial T2-adjusted back MR picture away from the patient with SS reveals an effective leftover T12 pseudomeningocele. B, Axial T2-weighted notice MR image of a patient which have SS suggests a posterior fossa liquid-filled range. C1 and C2, Sagittal (C1) and you will axial (C2) T2-adjusted cervical MR photographs from someone with SS let you know a great proper C7 pseudomeningocele (same diligent as that shown into the Fig 10B). D, Sagittal T2-adjusted back MR picture from someone which have SS reveals an intrasacral meningocele. E, Axial T2-weighted thoracic cable MR image shows a liquid-filled collection prior into the back. F, Sagittal T2-weighted MR image reveals good longitudinally detailed liquid range ventral so you can new cable. The fresh dotted arrow reveals tethering of one’s cord from the T9 
. Grams, Sagittal T2-adjusted lower back MR visualize from someone which have SS reveals multiple intraspinal water-filled loculations.

T2-weighted MR imaging suggests a good rim out-of hypointensity around the cerebellum (Fig 1A, -B) and you can head stem (Fig 1C?E). The fresh new limited T2 hypointensity may also include new Sylvian fissure (Fig 1F), interhemispheric fissure (Fig 1G), and you may cortical sulci (Fig 1H). The new advanced vermis, quadrigeminal dish, and you may basal emotional surface try preferentially influenced by the latest marginal T2 hypointensity. Hemosiderin deposition can certainly be viewed with each other cranial anxiety II, V, VII, and you will VIII (Fig 1I). The new peripheral nervous system isn’t involved in SS. There is certainly a sharp cutoff on the spine origins and you will cranial anxiety within junction between the peripheral Schwann mobile phase and the fresh new main glial segment. 41 Cerebellar atrophy often is introduce, therefore the superior vermis and prior cerebellar hemispheres can be preferentially inside it from the atrophy (Fig 1J). The new gliosis and you can neuronal losings regarding the hemosiderin deposition could possibly get result during the enhanced laws intensity regarding the adjacent cerebellar tissue. twenty two,twenty six Instead, it could be simply an evident improve considering the overlying hypointensity. Hardly, an excellent hyperintense rim could be viewed on T2-weighted imaging. 26 It due to methemoglobin and you may is short for a recent episode of subarachnoid hemorrhage.
