"T1: most are isointense to hypointense; mixed-signal lesions are seen if cyst formation, tumour necrosis or haemorrhage has occurred"
"T2: hyperintense"
"T1 C+ (Gd): virtually all enhance strongly, somewhat inhomogeneously"
"Spinal ependymomas with MYCN-amplification are, in contrast, aggressive tumours with poor prognosis and frequent early dissemination throughout the central nervous system and reoccurrence despite resection10."
"In a small subgroup of patients, MYCN-amplification is identified. This is a distinct tumour and is now recognised as a separate entity in the 5th edition (2021) of the WHO classification of CNS tumours 10."
"Spinal ependymomas with MYCN-amplification are high-grade aggressive tumours, however, they are yet to be given a formal grade in the 5th edition (2021) of the WHO classification of CNS tumours 10."
"Spinal ependymomas with MYCN-amplification are, in contrast, aggressive tumours with poor prognosis and frequent early dissemination throughout the central nervous system and reoccurrence despite resection10."
