Acquired torticollis in children.

Acquired torticollis in children is a symptom that may be due to a number of underlying causes, some of which are severe and life threatening. Musculoskeletal, ophthalmologic, infectious, neurologic, and neoplastic conditions may present early with only torticollis. Because torticollis is a symptom, the broad spectrum of possible diagnoses requires a thorough and methodical workup. A wide variety of tests may be necessary, as well as specialty consultation. No matter how common or rare the disorder, it must be considered when evaluating a child with acquired torticollis. The first step in evaluation is always a careful and complete physical examination. An outline of the disorders associated with torticollis is presented, as are illustrative case histories.
