Necrotizing arteriolitis of ileum, as the initial manifestation of malignant hypertension in childhood.

Intestine is seldom a site of clinical manifestation of malignant hypertension, particularly in childhood. This report deals with a case of malignant nephrosclerosis superimposed on benign nephrosclerosis which probably resulted from a unilateral obstructive uropathy and chronic pyelonephritis. Clinical features included severe hypertension, neuroretinopathy with retinal exudate and hypertensive encephalopathy. An acute abdomen due to transmural infarction of the ileum caused by multiple thrombotic occlusion of necrotizing arteritis involving bowel wall and the mesentery was noted.
