Vertebrobasilar artery dissection manifesting as Millard-Gubler syndrome in a young ischemic stroke patient: A case report

BACKGROUND: Millard-Gubler syndrome (MGS) is caused by a lesion in the brainstem at the level of the facial nerve nucleus, and it is also a rare ventral pontine syndrome. Vertebrobasilar artery dissection (VAD) is an uncommon cause of ischemic stroke. To the best of our knowledge, this is the first case report on the coexistence of MGS and VAD in a young acute ischemic stroke patient. CASE SUMMARY: We herein describe an unusual case of young acute ischemic stroke patient, presenting with acute right peripheral facial palsy, right abducens palsy, and contralateral hemihypesthesia, manifesting as MGS. After receiving dual antiplatelet therapy with aspirin and clopidogrel, as well as rosuvastatin, the patient recovered significantly. The high-resolution magnetic resonance imaging (MRI) indicated a diagnosis of VAD. CONCLUSION: Our finding further demonstrated that high-resolution MRI is a useful technique to early detect underlying dissection in posterior circulation ischemic stroke.
