Abstract

Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological entity characterized by variable associations of headaches, encephalopathy, seizures, vomiting, visual disturbance, and focal neurological signs. Neuroimaging shows cerebral edema of different patterns, classically involving the parieto-occipital white matter. PRES has been associated with several conditions predominantly hypertension, eclampsia, and immunosuppressive therapy. However, constipation has not been previously described in association with the development of PRES. In this report, we describe an 11-year-old child with history of severe functional constipation who developed PRES, as a consequence of renovascular hypertension from severe fecal impaction. Both hypertension and neurologic dysfunction resolved after resolution of fecal impaction. Severe functional constipation is a previously unrecognized cause of severe acute hypertension, resulting in life-threatening neurologic dysfunction. We highlight this unrecognized complication of severe functional constipation with fecal impaction that is potentially preventable if managed appropriately.
