Acute glomerulonephritis presenting with PRES: a report of 4 cases.

OBJECTIVE

Posterior reversible encephalopathy syndrome (PRES) occurs most commonly in the setting of known hypertension or use of immunosuppressive agents.

DESIGN AND METHODS

We report four previously-well children who presented acutely with altered mentation, seizures and visual disturbances and were diagnosed with PRES.

RESULTS

Only one child had a history of gross hematuria prior to the seizure. All four were discovered to be hypertensive only after onset of their neurological symptoms, and were subsequently diagnosed with glomerulonephritis. All four had rapid resolution of neurological symptoms with adequate treatment of hypertension.

CONCLUSIONS

Blood pressure must be measured promptly in all children presenting with these symptoms. If elevated, the diagnosis of PRES should be strongly considered and a workup for renal disease pursued.
