Abstract
BACKGROUND Nummular headache and epicrania fugax are two primary headaches that fall under the heading of epicranial headaches. METHODS This article reviews the epidemiological and clinical features of nummular headache and epicrania fugax, proposed pathogenic mechanisms and state-of-the-art management, according to the literature. RESULTS AND CONCLUSIONS Nummular headache and epicrania fugax are generally viewed as rare headache disorders, but no population-based epidemiological data are available. Nummular headache is characterized by continuous or intermittent head pain, which remains circumscribed in a round or oval area of the scalp, typically one to six centimeters in diameter. Epicrania fugax manifests with brief paroxysms of pain that move along the surface of the head, following a linear or zigzag trajectory through different nerve territories. Nummular headache and epicrania fugax are mostly primary headaches, but some secondary cases have been reported. The pathogenesis of these headaches is not fully understood. Nummular headache could probably originate in epicranial tissues or adjacent intracranial structures, while the origin of epicrania fugax could be extracranial or intracranial. Diagnostic assessment requires careful examination of the symptomatic areas. Underlying disorders should be excluded by additional investigations, including neuroimaging and appropriate blood tests. No controlled clinical trials have been conducted in nummular headache or epicrania fugax. Analgesics and anti-inflammatory drugs, botulinum toxin and gabapentin are currently the most recommended treatment options for nummular headache. In epicrania fugax, the most used treatments are gabapentin, lamotrigine, and other antiseizure medications.

Abstract
Background Nontraumatic true superficial temporal artery aneurysm (STAA) is rare, and its characteristics and pathogenesis are unclear. Methods We report a case of STAA and performed a systematic review of PubMed, Scopus, and Web of Science using the keyword "superficial temporal artery aneurysm" to include studies on STAA reported through July 2022. We excluded studies on STAA associated with trauma, arterial dissection, infection, or vasculitis. Results A 63-year-old woman who underwent left superficial temporal artery (STA)-middle cerebral artery bypass surgery 8 years previously was diagnosed with an aneurysm located at the left STA. The blood flow volume estimated by ultrasonography was higher in the left STA than in the contralateral counterpart (114 mL/min vs. 32 mL/min). She underwent clipping surgery to prevent aneurysmal rupture without sequela. The lesion was diagnosed as a true aneurysm by histology. The systematic review identified 63 cases (including the present case) of nontraumatic true STAA. The median age of the patients was 57 (interquartile range [IQR]: 41-70) years. Most (90.5%) cases were detected as a palpable mass. Aneurysmal rupture occurred in only 1 (1.6%) case, despite the large size of aneurysms (median size: 13 [IQR: 8-20] mm) and the high frequency (33.3%) of aneurysmal growth during observation. Most (93.7%) patients underwent surgical resection of STAA without sequela. Conclusion Our findings suggest that the pathogenesis of true STAA is promoted by hemodynamic stress. The systematic review clarified patients' and aneurysmal characteristics and treatment outcomes, providing further insight into the pathogenesis of nontraumatic true STAA.

Abstract
Side-locked headaches are a common symptom having a wide-ranging differential. Unchanging in laterality, these headaches can represent neuralgias, trigeminal autonomic cephalgias, ophthalmologic disorders, otolaryngologic and craniofacial disorders, vascular disorders, and malignancy. In rarer situations, they have presented secondary to neurosurgical or dermatologic considerations. Loss of cranial nerves and visual changes warrant additional evaluation.

Abstract
PURPOSE This article provides an overview of a diverse group of primary headache disorders that are categorized in the International Classification of Headache Disorders, 3rd Edition (ICHD-3), as "other primary headache disorders." This article provides clinicians with a distilled understanding of the diagnoses and their epidemiology, pathophysiology, and management. RECENT FINDINGS Cough-induced headache requires neuroimaging to exclude posterior fossa pathology and recently has been reported as a common symptom in patients with CSF-venous fistula. Clinical overlap is observed between patients with primary exercise headache and primary headache associated with sexual activity. Patients with recurrent thunderclap headache associated with sexual activity should be presumed to have reversible cerebral vasoconstriction syndrome until proven otherwise. De novo external-pressure headache is a common sequela among health care workers using personal protective equipment during the COVID-19 pandemic. New daily persistent headache is an important mimicker of chronic migraine or chronic tension-type headache and is distinguished by a daily-from-onset progression of persistent headache; a treatment-refractory course is often observed, and early involvement of a multidisciplinary team, including a psychotherapist, is advised. SUMMARY Patients with primary headache disorders that are classified as "other primary headache disorders" have presentations with unique diagnostic and management considerations. The disorders are highly recognizable, and an appreciation of the diagnoses will aid clinicians in providing safe and effective care for patients presenting with headache.

Abstract
BACKGROUND Nummular Headache (NH) is defined in the International Classification of Headache Disorders (ICHD) by the presence of localized pain circumscribed to a small round area of the scalp, not better accounted by any other diagnosis. As in many other primary headache disorders, secondary cases might occur. To date, 13 secondary cases have been published. We aim to present a long series of secondary NH and review the literature of symptomatic NH. PATIENTS AND METHODS Retrospective analysis of an observational prospective cohort in a headache unit located in a tertiary hospital. We included patients that fulfilled ICHD criteria and were attributed to a secondary cause. We describe the clinical characteristics, the underlying causes, and the response to treatment. RESULTS We included 274 NH patients, 8 of them (2.9%) were considered secondary. In 1 patient the underlying cause was subcutaneous, as for 6 cases the lesion was located in the bone (two hemangiomas, 1 osteoma, 3 different types of cysts), and in one was intracranial but closely related with internal diploe (cavernoma). Among our patients with secondary NH, a preventive therapy was not always needed and, when required, gabapentin or onabotulinumtoxinA were used with positive response. CONCLUSION Secondary NH phenotype overlaps primary NH. Therefore, we recommend routine imaging study in every NH patient. Concerning treatment, it was not necessary to remove the underlying lesion to control the pain and many cases responded to the same prophylactics as primary NH cases.

Abstract
PURPOSE OF REVIEW The purpose of this manuscript is to shed light on systematic work-up of a diagnostic challenge such as nummular headache (NH), and to summarize the relevant literature on NH. RECENT FINDINGS The specific nature of the shape of the pain site is usually characteristic of NH. Multiple modalities of investigation including succinct imaging are necessary to successfully rule out other similar conditions. A 26-year-old female patient of Asian-Indian origin presented to the clinic 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 diagnosis of nummular headache is challenging and confusing due to the rare occurrence and inadequate references in the literature. Appropriate imaging was done, which revealed no pathology that could explain the headache presentation. These findings are consistent with our diagnosis of nummular headache, and helped in the successful management of the case.

Abstract
Nummular headache (NH) is an uncommon primary headache characterized by pain limited to a precise small area of the scalp. There is no global consensus on its pathogenesis, but its extracranial origin is the most accepted theory. Moreover, peripheral mechanism is supported by the overlapping symptomatology of secondary forms of NH and is well described in the literature. However, a standard effective treatment is still lacking. METHODS A literature search according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines was conducted to evaluate surgical strategies for NH. Inclusion criteria were English language, diagnosis of primary NH according to International Classification of Headache Disorders, 3rd Edition, or of secondary NH, and follow-up at a minimum of 3 months. The treatment had to consist of peripheral surgery. RESULTS One hundred eighty-seven records were identified after duplicates were removed, 15 full-text articles were assessed for eligibility, and 4 records were selected for inclusion. A total of 53 patients were included in this review, 50 of whom were diagnosed with primary NH. The general positive response after surgery (>50% reduction in occipital migraine headaches) was about 70.0% for primary NH, while secondary NH always showed complete pain relief. However, many variations in patient selection and type of surgery were described. CONCLUSIONS Neurovascular relationship in the extracranial tissues seems to be involved in the onset of NH. However, only limited data from meager literature and from few patients are currently available. Shared multicentric research protocols are badly required.

Abstract
BACKGROUND/OBJECTIVE Nummular headache (NH) is a primary headache disorder characterised by intermittent or continuous scalp pain, affecting a small circumscribed area of the scalp. As there are limited data in the literature on NH, we conducted this review to evaluate demographic characteristics and factors associated with complete resolution of the headache, and effectiveness of treatment options. METHODS We performed a systematic review of cases reported through PubMed database, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol and 'nummular headache', 'coin-shaped headache' and 'coin-shaped cephalalgia' keywords. Analysis was performed by using χ2 test and Wilcoxon rank-sum test. For individual interventions, the response rate (RR%) of the treatment was calculated. RESULTS We analysed a total of 110 NH cases, with median age 47 years and age of pain onset 42 years. Median duration to make correct diagnosis was 18 months after first attack. The median intensity of each attack was 5/10 on verbal rating scale over 4 cm diameter with duration of attack <30 min. Patients with NH had median three attacks per day with frequency of 9.5 days per month. 40 (57.97%) patients had complete resolution of the headache after treatment. Patients with complete resolution were younger, more likely to be female, and were more likely to have diagnosis within year. Patients with complete resolution more likely to have received treatment with onabotulinum toxin A (botulinum toxin type A (BoNT-A)), and gabapentin compared with patients without complete resolution. Most effective interventions were gabapentin (n=34; RR=67.7%), non-steroidal anti-inflammatory drugs (NSAIDs) (n=32; RR=65.6%), BoNT-A (n=12; RR=100%) and tricyclic antidepressant (n=9; RR=44.4%). CONCLUSION Younger patients, female sex and early diagnosis were associated with complete resolution. NSAIDs, gabapentin and BoNT-A were most commonly used medications, with significant RRs.

Abstract
BACKGROUND Head trauma has been described as a precipitating event in Nummular Headache (NH). We aimed to describe the largest NH published series and compare characteristics between idiopathic and post-traumatic cases. METHODS Patients attended in a Headache Unit in a tertiary hospital (January 2008-January 2018). NH diagnosed according to International Classification of Headache Disorders (ICHD) criteria. We prospectively considered clinical and epidemiological data, comparing idiopathic cases with those precipitated by a cranial trauma. RESULTS We included 225 patients (145 women, 80 men) with NH. Median latency between onset and diagnosis was 10 months (IQR: 5-24). Symptomatic treatment was used in 190 patients (84.4%) among which 142 (74.7%) experienced response to it. Preventive treatment was necessary in 127 patients (51.4%), among which 95 (74.8%) achieved response. 29 patients (23 women, 6 men) described a head trauma related to beginning of pain. When comparing groups with or without previous trauma, age of onset was higher among post-traumatic patients (59.9 ± 17.4 vs 48.1 ± 18 years, p: 0.001). Allodynia upon palpation was encountered more frequently in trauma triggered painful areas (53.3% vs. 32.7%, p: 0.02). No other clinical characteristics differences were observed. CONCLUSION Cranial trauma is not a rare trigger of NH. Patients with post-traumatic forms are older and the presence of allodynia is more frequent.

Abstract
Nummular headache (NH) is an unusual disorder attributed to a dysfunction of the epicranial nerves. We report a new series of cases, highlighting some clinical features, the association with other headaches, and the therapeutic response. Data of patients with NH, fulfilling ICHD-3 criteria, observed in a Headache Outpatient clinic during 5 years, were retrieved from records. Response to onabotulinumtoxinA was recorded prospectively and evaluated with a Headache Impact Test (HIT). Twenty-four patients, aged 53.8 (±14.6) years at diagnosis, 13 women, had definitive ( N = 21) or probable ( N = 3) NH for an average of 2.4 years. Headache was consistently localized, more frequently extratrigeminal ( N = 15) and parietal, and confined to the scalp. Pain was unremitting since onset in 58.3% of mild-to-moderate severity often with superimposed paroxysms (66.7%) and local allodynia (70.8%). In five cases, there was a possible precipitant. Thirteen patients reported other headaches, preceding NH by 8.2 years. In eight persistent cases, there was a significant improvement on HIT, after onabotulinumtoxinA. Despite its persistence, NH may go unrecognized for years. It often follows other headache types and has some tropism for hair-covered regions of the scalp. OnabotulinumtoxinA seems effective in persistent cases.
