Transient thalamic hypodensity in lupus erythematosus with generalized seizures

Computerized tomography revealed extensive bilateral hypodensity of the thalamus after an episode of severe arterial hypertension and convulsions in a patient with systemic lupus erythematosus. Radiologic and neurologic abnormalities were substantially resolved 1 week later. The unusual radiologic findings are discussed in relation to possible unique characteristics of vascular permeability in the thalamus.
