Hypertrophic olivary degeneration: A clinico-radiologic study.

ABSTRACT:

Introduction

The frequency and causes of hypertrophic olivary degeneration (HOD) are unknown. We compared the clinical and radiological characteristics of unilateral HOD and bilateral HOD.

Methods

We performed a search of a radiologic report database for patients who were radiologically diagnosed as having HOD. This database includes the patients examined at the Mayo Clinic in Florida and Arizona. We used the search terms "hypertrophic olivary degeneration", "HOD", and "olivary" in the reports recorded from 1995 to 2015.

Results
