Background: Microvascular ocular cranial nerve palsy can result from diabetes and hypertension and may be increasing with the increase in the incidence of diabetes and hypertension in Nigeria. Objective: This study provides clinical considerations for the neuro-ophthalmic evaluation of diplopic patients with presumed microvascular ocular cranial nerve palsy. Method: A case report is presented o...

Reprint requests to: Dr. Te-Chang Wu Department of Radiology, Chi-Mei Foundation Hospital. No. 901, Chung Hwa Road, Yong-Kong, Tainan 710, Taiwan, R.O.C. Three children of unilateral type I Duane’s retract ion syndrome (DRS), aged 8 years, 14 months and 2 years were confirmed by demonstration of absence of ipsilateral abducens nerves on 3D fast imaging employing steady-state acquisition (FIESTA...

Intracranial dural carotid cavernous fistulas account for 10 to 15% of all intracranial arteriovenous malformations. Although these fistulas tend to regress spontaneously, permanent neurological deficits are observed in as many as 20-30% of untreated patients. In general, transvenous or transarterial embolization of the fistula is a safe and successful treatment option. Depending on the amount ...

Most isolated abducens (sixth) nerve palsies are ischaemic in nature. However, there are other causes that can mimic an abducens nerve palsy, which requires aggressive diagnostic management. A 56-year-old hypertensive woman presented with a right abduction deficit. Her past history revealed that she had undergone a mastectomy and completed a course of chemo- and radiation therapy for breast car...

The abducens nerve paresis generally can aid in the presumptive diagnosis of abducens schwannoma along with the typical radiological features of schwannomas. The authors present a case of a 76-year-old male patient with a abducens schwannoma without abducens nerve paresis. Peroperatively, abducens nerve located in the cerebellopontine cistern had normal in contour and diameter, despite the mass...

A 7-year-old boy underwent resection of a posterior fossa medulloblastoma. Two days later, he developed facial diplegia, left abducens nerve palsy, and mild hypalgesia below the neck. MRI documented 2 dot-like ischemic foci in the pons (figure). We diagnosed the unusual bilateral occurrence of Gasperini syndrome, a lesion of the sixth and seventh cranial nerve nuclei and the lateral spinothalam...

We report the case of a 43 year old man who presented recurrent left abducens palsy. His medical history included arterial hypertension, ischemic cardiomiopathy, dyslipidemia, rhinitis, maxillary sinusitis. Physical examination revealed a overweight patient, horizontal gaze diplopia, left nerve VI paresis, mild left retro-orbital pain. The orbital MRI also didn't offer new information: mild ext...

Introduction: Cranial traction leading to 6th nerve palsy is the main cause of developing diplopia following spinal surgery. Very few cases of abducens nerve palsy as a complication of surgery without cranial traction have been described. We review a series of four patients who developed diplopia following spinal surgery only one of which had cranial pins or apparent traction on the abducens ne...
