Baclofen withdrawal presenting as irritability in a developmentally delayed child.

Irritability in children has a broad differential diagnosis, ranging from benign processes to lifethreatening emergencies. In children with comorbid conditions and developmental delay, the diagnostic process becomes more challenging. This case report describes a developmentally delayed 14-year-old boy who presented with pain and crying caused by a malfunction of a surgically implanted baclofen pump. We describe recommendations concerning the diagnostic evaluation, medical management, and surgical repair. [West J Emerg Med. 2012;13(4):373-375.]
