Magnetic resonance imaging findings in lupus ataxia.

We present a 47-year-old white woman who had a definitive diagnosis of systemic lupus erythematosus (SLE), and developed cerebellar ataxia of sudden onset. MR imaging showed changes characteristics of cerebellar infarct. Due to the absence of vascular risk factors and to the previous diagnosis of SLE, we postulate that the cerebellar infarct is related to SLE. We are not aware of previous descriptions of the MRI findings in lupus ataxia.

Tegmental pontine hemorrhages: clinical features and prognostic factors.

We report six patients with partial, predominantly paramedian, tegmental pontine hemorrhages. Constant clinical manifestations consisted of: ipsilateral miosis, horizontal gaze paresis, lower motor neuron facial paresis, contralateral hemisensory loss and mild and transitory hemiparesis, dysarthria and mild or no compromise of consciousness. Five out of six were hypertensive. All patients survived with mild sequelae, oculomotor disturbances being the most persistent deficit. We found in our patients that a transverse diameter of less than 17 mm, unilaterality of the injury and absence of coma were the major indicators of a favorable outcome.

Risk factors for developing seizures after a stroke.

We evaluated development of seizures in 219 consecutive patients who had ischemic or hemorrhagic stroke. Subjects with transitory ischemic attacks, subarachnoid, subdural, and epidural hemorrhages or those with previous history of epilepsy were excluded. Mean follow-up time was 11.5 months (range 1-72 months). Twenty-two of 219 stroke patients (10.04%) had seizures. Twelve (54.55%) were of early onset (< 1 month after the stroke), and 10 (45.45%) were of late onset. No statistically significant differences were evident between the early- and late-onset seizure group in comparisons of type of stroke, localization, and size of the lesion. Six of 22 patients (27%) had seizure recurrence. Seizures developed in (a) 13 of 183 patients with ischemic stroke (7.1%) and 9 of 36 patients with hemorrhagic stroke (25%) (p = 0.01); (b) 16 of 93 patients with cortical lesions (17%) and 6 of 126 patients with subcortical lesions (4.7%) (p = 0.01); and (c) 14 of 66 patients with a lesion comprising more than one lobe (21.2%) and 8 of 153 patients with a lesion comprising less than one lobe (5.2%) (p < 0.01). We conclude that patients with hemorrhagic stroke, cortical lesions, and lesions involving more than one lobe are at higher risk of developing seizures.
