Isolated sixth nerve palsy: an uncommon presenting sign of multiple sclerosis.

We describe three patients in whom an isolated sixth nerve palsy was the only clinical symptom or sign of multiple sclerosis (MS). Data were collected prospectively over 6 years on these three patients, who showed no other signs of brainstem dysfunction or prior symptoms; in addition. Retrospective analysis of all patients with MS and all patients with sixth nerve palsy referred to a neuro-ophthalmology service between 1982 and 1998 showed isolated sixth nerve palsy to be the presenting sign of MS in only 0.5% of these patients. MS was the cause of isolated sixth nerve palsy in 0.8% of all patients and in 1.6% of those aged 18-50 years. Although it has been previously suggested that sixth nerve palsy is a not uncommon presenting sign of MS, our results suggest it is rare.

Arachnoid cyst of the cavernous sinus resulting in third nerve palsy.

A 67-year-old man exhibited long-standing left third nerve palsy. Magnetic resonance imaging revealed a cystic lesion in the left cavernous sinus with signal characteristics typical of arachnoid cyst. Intradural cavernous sinus arachnoid cyst has not reported previously. Pathogenetic mechanisms are discussed.

Effects of weight loss on the course of idiopathic intracranial hypertension in women.

OBJECTIVE: To determine the role of weight loss in the treatment of idiopathic intracranial hypertension (IIH) in obese women. METHODS: Chart review of 250 patients with suspected IIH revealed 58 women who met our criteria, did not undergo early surgical intervention, and had adequate documentation of visual status, papilledema, and weight at the baseline evaluation and at 6 months or longer. Patients were divided into two groups based on whether weight loss > or = 2.5 kg occurred during any 3-month interval. Papilledema grade, visual acuity, and visual field grade at 6 months or longer and the time to improve each were recorded. RESULTS: Mean time in months to improve one grade for papilledema and visual field in one eye was 4.0 versus 6.7 (p = 0.013) and 4.6 versus 12.2 (p = 0.032), respectively, for the 38 patients with weight loss compared with the 20 patients with no weight loss. Papilledema resolved in 28/38 with weight loss (mean, 7.6 months) and 8/20 without weight loss (mean, 10.2 months; p = 0.352). There were no differences in final visual acuity or visual field between the two groups, but the papilledema grade was slightly better in the worst eye in each patient at baseline in the weight loss group (p = 0.03). CONCLUSIONS: Weight reduction is associated with more rapid recovery of both papilledema and visual field dysfunction in patients with IIH compared with those who do not lose weight.

Congenital and acquired lung hernias.

Lung hernia is defined as a protrusion of lung parenchyma beyond the confines of the musculoskeletal thorax. Lung hernias can be classified according to location (i.e., cervical, thoracic, or diaphragmatic) and etiology. Approximately 80% of reported cases of lung hernia are acquired, usually related to trauma or surgery. Symptoms are few, infrequent, and vague. A painless, local, and inconstant bulging is evident on physical examination. The diagnosis of a lung herniation is accomplished using chest radiographs in the most cases. Surgery is usually reserved for large hernias or incarcerated hernias.
