title: Systemic lupus erythematosus with presentation as vertigo and vertical nystagmus: report of one case.
abstract: An 11-year-old boy suffered from fever, headache, severe vertigo and unsteady gait. Physical examination showed bilateral vertical nystagmus, mild corneal reflex delay of the right eye and asymmetric facial expression. Laboratory data showed leukopenia, high ESR and normal CSF study. Brain CT showed diffuse brain edema. Electronystagmography showed upbeat nystagmus and central vertigo. EEG revealed diffuse slow wave and mild to moderate cortical dysfunction. MRI of the head showed focal abnormal signal intensity at the ventral portion of the medulla oblongata on both sides. Under suspicion of enteroviral encephalitis, mannitol and IVIG were given. The virological profiles were negative, ANA 1:640 nucleolar type, low complements and proteinuria. Anti-ds DNA was elevated and anti-ribosomal-P antibodies were positive. Under impression of SLE with CNS involvement, betamethasone was given. Fever, nystagmus and ataxia subsided gradually. Steroid was tapered and imuran was added. The following laboratory data were normal. In his past history, the patient was diagnosed Kikuchi disease. The manifestations of SLE were rare initial presentations as vertigo or vertical nystagmus. We present a case with review of literature and conclusion that physicians should keep in mind the possibility of SLE if patients present with unspecific neurological symptoms and concomitant systemic symptoms.
