Isolated superior oblique palsies with brainstem lesions

1999

Article abstract Isolated unilateral superior oblique palsies resulting from brainstem lesions occurred in three patients. MRI documented contralateral tegmental lesions of the trochlear nucleus and adjacent intraaxial trochlear nerve. Lacunar infarct was the cause in two patients and a small hemorrhage in a third.

Isolated superior oblique palsies with electrophysiologically documented brainstem lesions

2000

Over a 13.5-year period, we observed 10 patients with isolated superior oblique palsies in whom electrophysiological abnormalities indicated brainstem lesions. In 7 patients unilateral masseter reflex abnormalities were seen, and were located on the side of the superior oblique palsy in 2 patients and on the opposite side in 5 patients. Two patients had slowed gain of following eye movements to the side contralateral to the superior oblique palsy. Slowed adduction saccades in the eye contralateral to the superior oblique palsy were seen in 1 patient. Clinical improvement was frequently (in 7 of 10 patients) associated with improvement or normalization of electrophysiologic findings. Magneti…
