Lupus catatonia: a case report.

A 19-year old female with catatonia associated with multi-system involvement with systemic lupus erythematosus is described. There was no evidence of CNS involvement (negative CT scan, normal EEG, normal ice-caloric response, and normal CSF findings). The patient improved on large doses of steroids. It is suggested that cerebral lupus should be considered in the differential diagnosis of catatonia even in the absence of radiological and focal neurological signs when the active disease is present.
