T2-weighted (A) and gradient-reflect (T2*) (B) MR photos out of the patient that have SS have demostrated quality of the gradient-reflect approach from inside the detecting brand new feature T2 hypointensity, shown right here over the Sylvian and interhemispheric fissures.

A beneficial and you may B, Sagittal (A) and you may axial (B) T2-weighted back MR photo reveal hemosiderin deposition along (A) and to (B) the latest wire surface. Note associated big wire atrophy (A) (dotted arrow). C and you may D, Axial T2-adjusted MR pictures within amount of the fresh new cauda equina away from customers which have SS reveal peripheralization (C) and you will clumping (D) of your own nerve root on account of arachnoiditis. Elizabeth, A keen axial cut from the lumbar profile toward a good CT myelogram regarding a patient having SS reveals clumping off bravery roots from the newest cauda equina on account of arachnoiditis. F, T2-adjusted sagittal MR image of the latest lumbosacral city out of a patient with SS suggests an excellent lesion that has been suspected of being a great you’ll be able to source of the new persistent bleeding. A biopsy is actually performed, and you can blood services stringy structure had been imagined. Shallow siderosis: relationships and you can therapeutic implications.

A good, Axial T2-weighted spine MR image from a patient that have SS shows a kept T12 pseudomeningocele. B, Axial T2-adjusted attention MR image out of an individual having SS suggests a good rear fossa water-filled collection. C1 and you can C2, Sagittal (C1) and you will axial (C2) T2-adjusted cervical MR pictures from the patient that have SS reveal a good correct C7 pseudomeningocele (same diligent while the you to revealed for the Fig 10B). D, Sagittal T2-adjusted lower back MR visualize out of someone that have SS suggests a keen intrasacral meningocele. Elizabeth, Axial T2-weighted thoracic wire MR image suggests a fluid-occupied range prior into spinal cord. F, Sagittal T2-adjusted MR photo reveals a good longitudinally detailed fluid range ventral so you’re able to the fresh new wire. The latest dotted arrow reveals tethering of the cable within T9. G, Sagittal T2-weighted lower back MR photo from the patient that have SS suggests numerous intraspinal liquid-filled loculations.

T2-weighted MR imaging reveals an excellent rim out of hypointensity within cerebellum (Fig 1A, -B) and you may attention stalk (Fig 1C?E). The fresh marginal T2 hypointensity also can encompass brand new Sylvian fissure (Fig 1F), interhemispheric fissure (Fig 1G), and you may cortical sulci (Fig 1H). The latest superior vermis, quadrigeminal dish, and you will basal mind epidermis is actually preferentially affected by new marginal T2 hypointensity. Hemosiderin deposition can also be viewed together cranial nerves II, V, VII, and you may VIII (Fig 1I). This new peripheral neurological system is not in SS. There was a sharp cutoff on the spinal sources and you can cranial nervousness at the junction between the peripheral Schwann cellphone section and the central glial portion. 41 Cerebellar atrophy is often introduce, plus the premium vermis and anterior cerebellar hemispheres can be preferentially with it by the atrophy (Fig 1J). The newest gliosis and neuronal losings associated with hemosiderin deposition could possibly get result in enhanced code intensity on the adjacent cerebellar muscle. twenty-two,twenty six Instead, it can be simply an apparent increase due to the overlying hypointensity. Barely, an excellent hyperintense rim can be viewed on the T2-adjusted imaging. 26 It because of methemoglobin and you may signifies a recently available bout of subarachnoid hemorrhage.
