"tend to occur more commonly supratentorially."
"T1: mixed signal from differing components"
"T2: mixed signal from differing components"
"T1 C+ (Gd): solid soft tissue components show enhancement"
"atypical rhabdoid / teratoid tumour (ATRT): older age group"
"Intracranial teratomas are uncommon intracranial neoplasms, which can have a bewildering variety of components and thus a wide range of appearances. They can be divided into two broad categories, intra- and extra-axial, which differ in epidemiology and clinical presentation. Another method of classifying an intracranial teratoma is as mature, immature and mature with malignant transformation."
"These tumours are often large, heterogeneous, and lobulated, with components including solid, cystic, calcified, and sometimes fatty areas. Haemorrhage and necrosis can be present, especially in immature or malignant variants 7,9."
"mature teratomas: composed of well-differentiated tissues; generally benign"
"immature teratomas: contain embryonic or incompletely differentiated tissues; potential for malignancy"
"extra-axial lesions: largely depends on the size and location; smaller lesions can be successfully resected with good prognosis"
