Cyclic fluctuation of blood pressure in neonatal neuroblastoma.

Herein is described a case of neonatal neuroblastoma with cyclic blood pressure fluctuation and elevated catecholamines. The fluctuations stabilized after treatment with α-adrenergic blocker and the perioperative course was uneventful. The possibility of catecholamine-related symptoms including hypertension, heart failure, and blood pressure fluctuations should be considered in the treatment for neuroblastoma; if they are present, treatment with α-blockers is effective.
