RESUMO
Sixteen syndrome is rare variant of one and a half syndrome resulting from lesion affecting bilateral dorsal pontine structures. This report describes a case of 16 syndrome in systemic lupus erythematosus (SLE). A 28 year old woman with underlying lupus was presented with sudden left side body weakness and diplopia. Examination showed features of 16 syndrome with one and a half syndrome, facial diplegia and left hemiparesis. Neuroimaging revealed an acute infarct of bilateral dorsal pons. The patient was placed on antiplatelet therapy. However, she developed left leg deep vein thrombosis and pulmonary embolism after one week. She was then given subcutaneous low molecular weight heparin, followed by warfarin and cycles of cyclophosphamide. Her hemiparesis, ocular symptoms, and facial diplegia improved after one year. SLE increases the risk of stroke and thrombotic events in a young patient. Achieving disease remission is important to prevent stroke in SLE patients.
