Paroxysmal torticollis of infancy (PT) was first described by Snyder in 1969.1 The 12 patients he described began having recurrent attacks of head tilt between 2 and 8 months of age. The spells lasted from a few hours to three days and were sometimes accompanied by pallor, vomiting, and agitation. Between episodes the infants were normal, and the attacks ceased prior to 5 years of age.
Since Snyder's description there have been few additional reports of PT, and to date no familial cases have been described. This communication presents our findings in two siblings with PT of infancy.
Report of Cases.—An 11-week-old boy was seen at University of Wisconsin Hospitals for evaluation of episodic torticollis. He was born of a 24-year-old gravida 3, para 3, whose pregnancy, labor, and delivery were reportedly uncomplicated. The infant weighed 4,363 gm at birth and was well until 14 days of age
