Posterior reversible encephalopathy syndrome in scrub typhus fever.

The clinical course of a 40-year-old female patient, who presented with acute febrile illness due to scrub typhus fever became complicated by seizures and posterior reversible encephalopathy syndrome (PRES), leading to a fatal outcome. She had normal blood pressure at admission; however, she later developed hypotension and shock. PRES is a syndrome of vasogenic cerebral oedema and accompanying neurological deficits resulting from the breakdown of blood-brain barrier due to high blood pressure or radical blood pressure changes. PRES is a clinico-radiographic diagnosis of heterogeneous aetiologies and is rare in the context of infections. Although there are many neurological manifestations in scrub typhus, to the best of our knowledge, PRES has never been reported.
