[Benign paroxysmal torticollis of infancy: diagnosis and clinical evolution of six patients].

Benign paroxysmal torticollis of infancy is an episodic disorder that occurs suddenly and spontaneously in the first months of life. The patient's head tilts to one side for hours or days, and sometimes it can be associated with other symptoms like vomiting, sweating, pallor, irritability, headache and unstable gait. We report six patients with benign paroxysmal torticollis of infancy, whose symptoms began within the first six months of life and disappeared by five years of age. It is important that the physician be able to recognize this benign disorder to provide appropriate prognosis and not do unnecessary exams which would only cause expenses and anxiety for the child and their parents.
