Posterior reversible encephalopathy syndrome in a patient with mixed connective tissue disorder: a case report

Our case report includes a 42-year-old female patient; a known case of Mixed Connective Tissue Disorder (MCTD) who presented with focal seizure. Magnetic Resonance Imaging (MRI) brain showed the features of Posterior Reversible Encephalopathy syndrome (PRES) to be the cause of seizure. Given the timely diagnosis of PRES, the seizure was controlled with anti-epileptic drug and the possibility of having poor neurological outcome was successfully prevented. Although Mixed Connective Tissue Disorder is rarely associated with PRES, MCTD should be considered when there are supportive clinical and radiological findings as in our case.
