Tegmento-vermian dysplasia: radiologic features of a novel described anatomic variation.

Here we present the incidental radiological findings of a case that has a huge pontine tegmental cap orienting posteriorly towards the fourth ventricle and continues with the inferior vermis, accompanied by a midline anterior midbrain cleft. Having knowledge about this variation will prevent a misdiagnosis of a posterior fossa tumor and eventual unnecessary biopsy or operation.

Comparison of Wiltse and classical methods in surgery of lumbar spinal stenosis and spondylolisthesis.

Aim: Minimally invasive approaches to posterior lumbar surgery are available today that can enhance patient comfort by greatly reducing tissue damage and offer better clinical results. However, such methods have not yet gained widespread popularity despite their significant advantages. This study compares the Wiltse method and the classical method of lumbar surgery based a cohort, clinical study of 57 patients.
