Anamnesis

Identification: A 32-year-old male patient reports recurrent episodes of moderate, pulsatile bifrontal headache lasting 10 to 30 minutes, occurring immediately after the ingestion of histamine-rich foods (e.g., aged cheeses, red wine).

Examinations/Investigation:

Clinical history and headache diary confirm a temporal correlation with histamine ingestion.

Oral provocation test (under medical supervision) reproduces symptoms.

Imaging studies (cranial MRI) are normal, ruling out other causes.

Report this case — e.g. suspected re-identification risk.
