Abstract

Posterior reversible encephalopathy syndrome (PRES) is a clinical syndrome characterized by headaches, seizures, a confusional state and visual disturbances associated with transient predominantly bilateral posterior white mater magnetic resonance imaging lesions. It is primarily reported in the setting of hypertension, acute renal failure, peripartum eclampsia, autoimmune disease, immunosuppression and chemotherapy. Thrombotic microangiopathy (TMA), including hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP) has also been reported as potential PRES inducer. The present study reviews two cases of patients with PRES, associated with TMA caused by chemotherapy. Their clinical and imaging data, and the relevant literature were reviewed. Patient 1 presented with TMA‑induced PRES following mitomycin‑C for metastatic colon adenocarcinoma. Treatment with steroids, plasma exchange, intravenous immuno­globulins, aspirin, antihypertensive drugs, and diuretics resulted in resolution of the neurological and imaging deficits. Patient 2 presented with TMA‑induced PRES following gemcitabine for metastatic breast carcinoma. Treatment was ineffective and the patient deteriorated despite verapamil, dexamethasone, and plasma exchange. In this report, the relevant literature regarding pathogenesis, treatment and prognosis of chemotherapy‑induced PRES associated with TMA was reviewed. We conclude that several chemotherapy agents may cause PRES through various pathogenic mechanisms, leading to clinical variability and divergent response to therapy.
