“…But the accompaniments of dizziness, head heaviness, photophobia and phonophobia, triggering factor of anxiety and response to flunarizine and sodium valproate make it obviously different from EF. In fact, this current coronal line-shaped head pain is much more consistent with the previously reported LH with the only difference in distributional direction, and the differences between LH and the interictal pain of EF had been listed in detail (Wang et al 2015 ). Thus, we may conclude that the coronal line-shaped head pain is different from EF.…”

BackgroundLinear headache (LH) has recently been described as a paroxysmal or continuous head pain restricted in a linear trajectory of 5–10 mm in width, linking one endpoint in occipital or occipitocervical region with another endpoint in ipsilateral nasion or forehead region. The sagittal line-shaped pain area of LH is close and parallel to a sagittal venous sinus, the superior sagittal sinus (SSS). For some patients, the LH had some features resembling the pattern of migraine without aura.Case descriptionA 45 year-old woman complained with a distinct headache for more than half years. The pain trajectory of the headache is confined to a coronal line-shaped area of 5–10 mm in width linking the two points in the bilateral temporal regions with the occipital protuberance. This coronal line-shaped pain area is close and parallel to a coronal cambered venous sinus complex, the combination of the confluences of sinus and the bilateral cavernous sinus (CS), superior petrosal sinus (SPS) linking the CS with transverse sinus (TS) and TS into which the SPS feeds. The patient had a past history of migraine without aura for 10 years and her son had a benign paroxysmal vertigo (BPV) for 12 years. Both of her coronal line-shaped headache and her son’s vertigo had well response to sodium valproate.Discussion and evaluationIts clinical characteristics were distinctly different from those of other two headache entities defined with topographical criteria, nummular headache and epicrania fugax, and different from other existing headache entities except for migraine without aura.ConclusionThe distinct coronal line-shaped headache is suggestive of a variant of LH, a coronal LH, and probably belongs to a subtype of migraine without aura as proposed for LH. This coronal LH reinforces the proposal of LH as a new headache syndrome or a subtype of a previously known headache syndrome, probably of migraine.

“…Pareja and Bandrés recently reported a patient with long-lasting linear interictal pain between the attacks of EF, and this interictal pain is similar to the LH pain (Pareja and Bandres, 2015 ). Wang et al have proposed that this linear interictal pain may be LH triggered by EF (Wang et al 2015 ), as EF can trigger the attacks of migraine and cluster headache (Jin and Wang, 2013 ), and LH has many clinical features similar to that of migraine (Wang et al 2014b ). Moreover, the LH pain area is correspondent to the scalp area innervated by the supraorbital nerve (SON) and the greater occipital nerve (GON), we need to differentiate LH from trigeminal (TN) and occipital neuralgia (ON) and some trigeminal autonomic cephalalgias (TACs) such as paroxysmal hemicrania (PH).…”

BackgroundLinear headache (LH) has recently been described as a paroxysmal or continuous fixed head pain restricted in a linear trajectory of 5–10 mm in width, linking one endpoint in occipital or occipitocervical region with another endpoint in ipsilateral nasion or forehead region. For some patients, this headache had some features resembling migraine without aura.MethodsWe made a prospective search of patients presenting with a clinical picture comprised under the heading of LH and we have accessed eight new cases. A detailed clinical feature of the headache was obtained in all cases to differentiate with cranial neuralgia, paroxysmal hemicrania, cervicogenic headache, nummular headache and migraine.ResultsThe eight LH patients complained of a recurrent moderate to severe, distending, pulsating, or pressure-like pain within a strictly unilateral line-shaped area. The headache duration would be ranged from 1 h to 2 days or persistent for 1–6 months with recurrent worsening of headaches. For some patients, this headache had couple of features similar to that of migraine pattern, such as accompaniments of nausea, vomiting, and phonophobia, diziness, triggering factors of noise, bright night, resting after physical activity, fatigue, menstruation, and response to anti-migraine therapy.ConclusionsThis description reinforces the proposal of LH as a new headache syndrome or a new variant of a previously known headache syndrome, probably of migraine.
