Spontaneous Spinal CSF Leaks Stratified by Age, Body Mass Index, and Spinal Level

Abstract

Type 1 CSF leaks occurred in younger patients with a normal body mass index, while patients with type 3 CSF leaks were relatively older and had an elevated body mass index. Type 1 leaks mostly occurred in the upper thoracic spine, and types 2 and 3 leaks mostly occurred in the lower thoracic spine.
