Abducens Nerve Palsy Associated with Ramsay-Hunt Syndrome: Hye Joo Rha, Jae Han Park; Res Vestib Sci. 2018;17(3):116-118. Published online September 18, 2018; DOI: https://doi.org/10.21790/rvs.2018.17.3.116

Abstract PDF: Ramsay-Hunt syndrome is an infectious disease caused by the varicella zoster virus. It is usually associated with facial and vestibulocochlear nerve palsy, but other cranial nerve dysfunction can be accompanied. We present a 68-year-old woman with abducens nerve palsy associated with Ramsay-Hunt syndrome. She showed abduction limitation of left eye with peripheral facial palsy and vestibulopathy of the left side. Varicella zoster virus polymerase chain reaction of cerebrospinal fluid was positive and internal auditory canal magnetic resonance imaging was revealed enhancement of labyrinthine segment of left facial nerve. Although abducens nerve palsy is uncommon feature of Ramsay-Hunt syndrome, but it can be developed by several different mechanisms.

A Case of Isolated Unilateral Abducens Nerve Palsy Caused by Clival Metastasis from Rectal Cancer: Won Hee Chung, Jeong Ho Park, Sun Ah Park, Ki Bum Sung; J Korean Bal Soc. 2006;5(1):78-80.

Abstract PDF: A wide variety of abnormalities, both primary to the nerve itself and secondarily involving the nerve, can cause isolated abducens nerve palsy. Skull base lesions are also regarded as possible causes of isolated abducens nerve palsy but clival metastasis from systemic malignancy has rarely been reported. We report a case of isolated abducens nerve palsy caused by clival metastasis from rectal cancer. Key Words : Abducens nerve palsy, Metastasis, Skull base, Rectal neoplasm

Isolated Abducens Nerve Palsy Caused by De Novo Pontine Cavernous Angioma: Jeong Ho Park, Won Hee Chung, Sun Ah Park, Ki Bum Sung; J Korean Bal Soc. 2006;5(1):70-73.

Abstract PDF: Cavernous angiomas are considered to be congenital in origin. Patients under age of 14 years usually does not require imaging because they are likely to have a benign abducens nerve palsy, unless they develop additional signs or symptoms of neurologic disease during observation. Here we report a case of an isolated abducens nerve palsy caused by overt hemorrhage from de novo formation of cavernous angioma in the pons. Cavernous angiomas of the brain stem should be considered as a possible cause of isolated abducens nerve palsy in young adult and MRI, including gradient-echo sequences should be performed. Key Words : Cavernous angioma, Abducens nerve palsy
