L2-L3 intradural disc herniation presenting with cauda equina: Case Report
Published on: 2020-01-16
Intradural disc herniation [IDH] was first described by Dandy-Walker in 1940. The ratio of intradural disc herniations to all disc herniations is 0.2% -0.3%. It is most commonly seen in L4-L5 [90%] level. The ratio of intradural disk hernias in L2-L3 to all intradural disc herniations is 1-2%. The Male / Female ratio is 4/1. It is most commonly seen between 50-60 years of age. The incidence of cauda equina syndrome in IDH is higher than in extradural disc hernias. Although MR is the gold standard, there is no definite method for preoperative diagnosis. In myelographic MRI, the total block may be seen. It should be kept in mind in the lumbar disc herniation presented with cauda equina syndrome.
