"T1 C+ (Gd): most enhance but to a lesser degree compared to intracranial pilocytic astrocytomas; the pattern of contrast enhancement is variable 1"
"Spinal pilocytic astrocytomas are associated with an excellent prognosis. 10-year and 20-year survival rates of between 80-100% have been reported in patients who underwent gross total resection. For those with incomplete (subtotal) resection, the 20-year survival rate ranges from 70-80%. Recurrence occurs in ~5% of totally resected tumours 8."

"Signal characteristics"
"There is no gender predilection."
"There is an association with neurofibromatosis type 1."
"Histology reveals reactive astrocytes with biphasic morphology (loose glial components and compact piloid regions), eosinophilic granular bodies, Rosenthal fibres and hyalinised vessels. There is a lack of mitotic figures and other high-grade features 4,5."
"Clinical presentation is similar to that of other intramedullary spinal tumours, with pain, weakness and sensory changes common."
