"T1: isointense or hypointense"
"T1 C+ (Gd): intense enhancement"
"T2: heterogeneously hyperintense (Antoni type A: relatively low; Antoni type B: high)"
"T2*: larger tumours often have areas of haemosiderin"
"There is also schwannomatosis, which consists of multiple schwannomas without the concomitant involvement of cranial nerve VIII."
"Conventional schwannomas are composed of spindle cells that demonstrate two growth patterns: Antoni type A and Antoni type B 7-9."

"The vast majority of schwannomas are sporadic, with a peak presentation in the 5th to 6th decades. There is no sex predilection 9."
"There is also schwannomatosis, which consists of multiple schwannomas without the concomitant involvement of cranial nerve VIII."
"Antoni type A pattern: elongated cells are thickly bundled and organised in fascicles. Palisades are occasionally observed; when they are prominent they constitute Verocay bodies. The cells also have fusiform nuclei and eosinophilic cytoplasm. Antoni type A is a strongly Periodic acid-Schiff (PAS) positive and immunoperoxidase assay for laminin 10."
"T2: heterogeneously hyperintense (Antoni type A: relatively low; Antoni type B: high)"
"most commonly found arising from large nerves, brachial and lumbosacral plexus and thus often in a paravertebral location"
