Reversible Posterior Leukoencephalopathy Syndrome in Systemic Lupus Erythematosus With Thrombocytopenia Treated With Cyclosporine

摘要

Thrombocytopenia is one of the common manifestations of systemic lupus erythematosus (SLE). Its treatment consists of corticosteroids and/or other immunosuppressive drug such as aza-thioprine, vincristine, cyclosporine, and mycophenolate mofetil. Common adverse reactions of immunosuppressive treatment are infections, hematologic and liver function abnormalities, but neurologic complications may also be seen. Reversible posterior leukoencephalopathy syndrome (RPLS) is a syndrome manifested by headache, nausea, vomiting, seizures, cortical blindness, and visual disturbances. Neuroimaging shows bilateral subcortical and cortical edema with prominent posterior distribution. Moreover, treatment with immunosuppressive drugs such as cyclosporine, cisplatin, ta-crolimus, and interferon-alpha can induce a condition resembling RPLS. We report a case of a young woman with SLE and thrombocytopenia, who developed severe perspiration, headache, and seizure after receiving cyclosporine. A brain magnetic resonance image showed multiple high signal intensities on T2-weighted images predominantly located at the parietooccipital lobe. The patient recovered completely clinically and radiologically after discontinuing cyclosporine.
