The cyclic nature of some of headache disorders is closely related to melatonin, which is secreted by the pineal gland. We report a 29-year-old male patient with a 2.5-year history of headaches that woke him in the middle of the night. These headaches were pulsatile and continued until sunrise. During these attacks he also suffered from allodynia over the scalp, bilateral conjunctival hyperemia, and nervousness. His brain MRI showed a 5 mm by 4 mm neuroepithelial cyst in the pineal gland. The peak plasma melatonin level that was measured at 2 am was 28 pg/mL. The patient underwent oral melatonin treatment (6 mg/day). After 1 month he experienced a 70% reduction in his symptoms. When the melatonin dosage was increased to 10 mg/day he became headache-free, and 5 months after the treatment began, had no complaints. His 5-month follow-up plasma melatonin level at 2 am was 61 pg/mL. To our knowledge this is the first report of a patient with nocturnal headache associated with a low level of melatonin due to a neuroepithelial cyst in the pineal gland.
