    • "Reviewing the literature, we find two important points probably relating to the occurrence of central NH. Firstly, besides of the previously reported three patients and our patient associated with involvement of sellar and regional structures,[11–13] there are another three NH patients in whom intracranial secondaries are found diffusely at cerebellar tentorium,[8] high parietal cortical area,[9] and parietotemporal cortical area,[9] respectively. These intracranial secondaries are exclusively located at the ipsilateral juxtameninges and are also close to the painful area in them.[89] "

    ABSTRACT: Nummular headache (NH) is a newly categorized headache disorder characterized by a consistent clinicographics in each attack. Currently, it is considered as a primary headache disorder due to epicranial neuralgia but the pathomechanism is still unknown. We report a woman, whose recurrent NH subsided after trans-sphenoidal surgery for her pituitary oncocytoma. The recovery of NH in this patient encourages the central mechanism for NH occurrence. After a review of literature concerning, NH and intracranial secondaries we propose that central NH is a referral pain from pain-sensitive structures, such as meninges, superimposing by pre-existing lower pain threshold or pain modulation.

    ABSTRACT: Nummular headache (NH) is a recently described headache syndrome where continuous or intermittent pain is localised to a coin-shaped region of the skull. NH can be a primary headache disorder or secondary to intracranial or extracranial pathology. We report a four-year-old boy who presented with nummular headache co-localised with a patch of discoloured hair and propose a common aetiology.
