Twenty-three patients were seen with entrapment neuropathy in a two-and-a-half-year period. Symptoms consisted of pain, paresis, and paraesthesia in the distribution of the common peroneal nerve. Some degree of paresis was often present, which in five patients was severe enough to cause drop foot. In 20 patients decompression of the entrapped nerve at the neck of the fibula was quickly and comp...

We describe a patient with a left trochlear nerve paresis and a left relative afferent pupillary defect despite normal visual acuity, color vision, visual fields, and fundus examination. Magnetic resonance imaging revealed a lesion in the right dorsal midbrain extending from the brachium of the superior colliculus to the inferior colliculus. The anatomy and physiology of the pupillary light ref...

Melkerssons-Rosenthal syndrome is a clinical entity identified by the presence of the triad of recurrent facial paralysis, recurrent often permanent (labial) oedema, and to a lesser extent the placation of the tongue. The striking event is that of recurrent lower motor facial paresis. This should arouse the search for the other components of the triad which is not always complete. The major wor...

A 47-year-old hypertensive man developed dysarthria suddenly. Examination revealed left hemiparesis and right hypoglossal nerve paresis without lingual atrophy or fasciculations (figure, A). A tongue EMG was normal. Brain MRI displayed an acute infarct in the right rostral pons (figure, B and C). The motor topography in the basis pontis is consistent with the rostral and medial localization of ...

Two unusual cases of monocular pendular nystagmus in patients with multiple sclerosis are reported. One patient showed regular horizontal oscillations of the right eye in abduction, associated with right abduction paresis. The second patient had a similar abnormal eye movement of the left eye in adduction, with partial left internuclear ophthalmoplegia. Such eye position-dependent monocular pen...

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...
