"Grading"
"Genotype"
"Although this is an area of some debate with alternative grading systems having been proposed, usually, solitary fibrous tumours of the dura can be graded from WHO grade 1 to grade 3; what was previously known as haemangiopericytomas representing WHO grade 2 or 3 tumours) 5,9."
"Surgical resection, if complete, is usually curative. Recurrence rates are variably reported as low to relatively high; up to 50% in one series 2. If incomplete or recurrence occurs, then radiotherapy may be employed 1."
"Importantly, lymphoma, Erdheim-Chester disease and melanocytic lesions may also have low T2 signal. Meningiomas may also be low on T2, usually in the setting of mineralisation/calcification; thus reviewing other sequences (T2*) or CT is useful."
"The radiographic appearances are those of a well-circumscribed mass arising from the dura (supratentorial convexity, falx and tentorium and posterior fossa). Unlike solitary fibrous tumours of the spinal cord, which most frequently arise from the cord itself and not the theca 2, parenchymal tumours of the brain are very rare."
