Dural tail sign seen associated with a meningioma. The dural tail sign (also known as "dural thickening", "flare sign", or "meningeal sign") is a radiological finding observed in magnetic resonance imaging (MRI) studies of the brain that refers to a thickening of the dura mater immediately adjacent to a mass lesion, such as a brain tumor.

Meningiomas have been divided into three types based on their patterns of growth. Histological factors that increase the grade include a high number of mitotic figures, necrosis and local invasion. Treatment of sphenoid wing meningiomas often depends on the location and size of the tumor. Gamma knife radiation and microscopic surgery are common ...
The falx cerebri is a strong, crescent-shaped sheet of dura mater lying in the sagittal plane between the two cerebral hemispheres. [3] It is one of four dural partitions of the brain along with the falx cerebelli, tentorium cerebelli, and diaphragma sellae; it is formed through invagination of the dura mater into the longitudinal fissure between the cerebral hemispheres.
Meningiomas are usually homogenously enhanced with dural thickening on MRI. [ 24 ] Treatment with radiation can lead to treatment induced changes in the brain, including radiation necrosis (death of brain tissue due to radiation treatments) visible on brain imaging and which can be difficult to differentiate from tumor recurrence.
