An Objective Study of Anatomic Shifts in Intracranial Hypotension Using Four Anatomic Planes

Purpose. Intracranial hypotension (IH) often remains undetected using current MR diagnostic criteria. This project aims to demonstrate that central incisural herniation is highly effective in helping to make this diagnosis. Materials and Methods. Magnetic resonance imaging (MRI) was analyzed in 200...

Description
Summary:Purpose. Intracranial hypotension (IH) often remains undetected using current MR diagnostic criteria. This project aims to demonstrate that central incisural herniation is highly effective in helping to make this diagnosis. Materials and Methods. Magnetic resonance imaging (MRI) was analyzed in 200 normal and 81 clinically known IH patients. MRI reference lines approximating the plane of the incisura, the plane of the diaphragma sella, the plane of the foramen magnum, and the plane of the visual pathway were utilized to measure the position of selected brain structures relative to these reference lines. Results. All IH patients had highly statistically significant (p
