Spontaneous remission of accelerated (malignant) hypertension in renal infarction

Malignant hypertension occurred in a young man who also was found to have a left renal infarct and higher renal vein renin levels on the left side. His hypertension was controlled with drugs and subsequently treatment with these medications was gradually discontinued over a period of nine months. He remained normotensive when no longer receiving medication, and another intravenous pyelogram demonstrated a persistent cortical defect in the left kidney.
