[Sacral perineural cysts. Contribution of magnetic resonance imaging].
In a 41-year old woman complaining of episodic bilateral sciatic pain, MRI showed large sacral cysts developed in the pelvis. The fact that these cysts communicated with the subarachnoidal spaces was not clearly demonstrated by CT. The mechanism underlying the development of this perineural variety of extradural cysts is discussed.
