A case of unilateral hypertrophic olivary degeneration following bilateral medial medullary infarction / 中华神经科杂志

ABSTRACT

Bilateral medial medullary infarction is a rare type of stroke. Hypertrophic olivary degeneration (HOD) is usually secondary to the lesion involving the Guillain-Mollaret triangle with vacuolar degeneration of inferior olivary nucleus neurons and enlargement of inferior olivary nucleus. The primary lesions involving the Guillain-Mollaret triangle are usually located in midbrain, pons and cerebellum. A case of unilateral HOD secondary to bilateral medial medullary infarction is reported and the clinical characteristics, diagnosis and treatment are analyzed in order to improve the understanding of HOD.
