Pseudocyst of the auricle was observed in two men with neurological disorders: a 33-year-old Asian man with spinocerebellar ataxia and a 47-year-old Caucasian man with Friedreich's ataxia. Patients with neurological disorders, particularly those associated with ataxia and/or dyskinesias, may have an increased risk of developing the traumatic variant of the condition.
