Intradural disc herniation with cranial migration of an excluded fragment

Clin Imaging. May-Jun 2004;28(3):170-2. doi: 10.1016/S0899-7071(03)00147-5.


Intradural herniation is a rare complication of the intervertebral disc disease. The history and present clinical findings may suggest the diagnosis. Although the myelographic signs are well known, intradural hernias have seldom been illustrated by magnetic resonance imaging (MRI). We present the case of an intradural disc hernia with cranial migration of a sequestrated fragment illustrated by both myelography and MRI. To our knowledge, such a case has never been reported in the literature so far.
