title: 'Clicking-brain syndrome': a curious cause of insomnia.
abstract: This case report describes a curious cause of insomnia. A 93-year-old woman presented to our follow-up clinic with the complaint of insomnia secondary to an audible click emanating from her skull. The site of loud biphasic-sound production corresponded to an area of the scalp where a squamous cell carcinoma had been removed 11 years previously.
