Nummular Headache - A case report of a rare entity
Abstract Background: Nummular Headache is a rare type of chronic primary headache wherein the pain is usually located in a well-circumscribed, round or elliptical shaped area of the scalp. Case Report: A 26-year-old female presented to the Center for TMD/ OFP with the chief complaint of chronic persistent left parietal headache, for more than 10 years, which has been worsening over the past few days with no specific identifiable trigger. The medical history is non- contributory. The primary diagnosis is Nummular Headache. Conclusion: A comprehensive history is the first step to achieve an accurate diagnosis. The diagnosis of Nummular Headache is challenging and confusing due to the rare occurrence. An examination must include imaging and is detrimental in eliminating other underlying pathologies. The diagnosis is made from distinct clinical features after exclusion of all other entities.
