[Differential diagnostic and therapeutic problems in a neuroblastoma patient with hypertension].

A 2 1/2 year old dystrophic girl with polyuria and polydipsia was found to have an arterial hypertension, increased catecholamines in serum and urine, and a suprarenal tumour was diagnosed by ultrasonic scan. By means of histology and staging a neuroblastoma grade 3 was revealed. The sonography and Iodine-benzyl-guadinin-scintigraphy gave the clearest information about the tumour. Before operating it is necessary to stabilize the blood pressure at a normal level with alpha and beta blocking substances, in order to reduce the risk of an intraoperative hypertonic crisis and a vasodilative shock after tumour extirpation.
