Spinal meningioma magnetic resonance imaging
well-circumscribed.
broad-based dural attachment.
dural tail sign
They share similar signal characteristics to typical intracranial meningiomas:
T1
Isointense to slightly hypointense
may have a heterogeneous texture
T2
Isointense to slightly hyperintense
T1 C+ (Gd)
Moderate homogeneous enhancement
Occasionally, densely calcified meningiomas are hypointense on T1 and T2, and show only minimal contrast enhancement.
