Acute Respiratory Failure Caused by Lateral Medullary Infarction - An Unknown Condition with Varied Etiology and Requiring Special Vigilance: A Case Series.

Abstract

Acute respiratory failure (ARF) due to lateral medullary infarction (LMI) can be a fatal condition, although its details remain unclarified. To clarify clinical aspects of ARF due to LMI, we reviewed eight applicable cases treated in a tertiary hospital. Of them, we focused on the detailed clinical course of one case. We clarified that even patients with a serious clinical course may have no apparent magnetic resonance imaging abnormalities in respiratory control centers at the initial examination. We should be mindful that respiratory monitoring is necessary even without infarction of regions responsible for respiratory control at the initial presentation.
