Three-dimensional Imaging of Abducens Palsy by Neurovascular Compression

Periodic abducens nerve palsy in adults caused by neurovascular compression.

Unilateral abducens nerve palsy with periodic recurrences is a well-recognised finding in children, but is rare in adults. The underlying pathophysiological mechanism is unknown. Vascular compression of the nerve is suspected but never demonstrated. We describe an adult patient with, altogether, 11 periods of unilateral right-sided abducens palsy and arterial contact at the root exit zone of th...

Isolated hypoglossal nerve palsy caused by neurovascular compression.

An 80-year-old man presented with difficulty in swallowing and speaking which had progressed over one year. Neurological examination revealed right hypoglossal nerve palsy with ipsilateral atrophy (Picture A). Laryngoscopic examination was unremarkable. Slowly progressive dysarthria and dysphagia with tongue atrophy initially indicated motor neuron disease (MND), but needle electromyographic ex...

Benign Isolated Abducens Nerve Palsy

Cranial nerve VI (abducens nerve) innervates the lateral rectus muscle. Acquired isolated abducens nerve palsy in infants and children is a rare condition. A lesion of abducens nerve will result in esotropia greater at distance, an ipsilateral abduction deficiency, and a double vision. The abducens nerve palsy in a child may be caused by serious neurological diseases such as raised intracranial...

Nasopharyngeal malignancies causing abducens palsy.

Four patients with nasopharyngeal malignancies were reported. The main symptom was diplopia due to abducens palsy in all patients; it was unilateral in three patients and bilateral in one. Skull tomographic evaluation was valuable for detecting nasopharyngeal malignancies. Histological examination of biopsy specimens from the nasopharynx confirmed these lesions to be squamous cell carcinoma in ...
