Posterior reversible encephalopathy syndrome secondary to malignancy-associated hypercalcemia: A case report.

ABSTRACT

Posterior reversible encephalopathy syndrome (PRES) is a reversible clinical syndrome usually characterized by a range of neurological manifestations and distinctive neuroimaging findings reflecting vasogenic edema. PRES has been described in the context of various clinical settings including renal failure, blood pressure fluctuations, use of cytotoxic drugs, autoimmune disorders and eclampsia. Hypercalcemia is rarely associated with PRES. We report a patient with lung cancer presenting as PRES secondary to hypercalcemia.
