Trigeminal Cephalgias and Facial Pain Syndromes Associated with Autonomic Dysfunction

Population-based prevalence of cranial autonomic symptoms in migraine and proposed diagnostic appendix criteria

BACKGROUND

Migraine with cranial autonomic symptoms is well described in the literature, but its prevalence in previous studies varies enormously. A precise estimate of the prevalence in a population-based material is important because migraine with cranial autonomic symptoms might represent an endophenotype, in which genetic and pathophysiological features differ from those without cranial autonomic features. The aim of the present study, therefore, was to estimate the prevalence in a big population-based sample using both questionnaire-based diagnosis (N = 12,620) and interview-based diagnosis (N = 302). We validate questionnaire-based diagnosis of migraine with cranial autonomic symptoms and develop the first diagnostic criteria for future research of this possible endophenotype.

METHODS

The Danish Blood Donor Study included 127,802 persons who all received a migraine diagnostic questionnaire. Participants who had answered the diagnostic questionnaire constituted the Danish Migraine Population Cohort (N = 62,677) of whom 12,620 had migraine. The diagnostic migraine questionnaire included questions about the following cranial autonomic symptoms: Facial/forehead sweating, lacrimation, ptosis, conjunctival injection, rhinorrhea, nasal congestion, and miosis. Validation was performed by a follow-up semi-structured, purpose-built interview of 302 participants with migraine, where detailed questions were asked to ascertain the validity of the symptoms.

RESULTS

The questionnaire-based prevalences of one, respectively two cranial autonomic symptoms were 57% and 31%. The semi-structured interview-based prevalences of one, respectively two symptoms were 44% and 22%. The most common symptoms were facial/forehead sweating (39%) and lacrimation (24%). The specificity of the questionnaire was 80% and the sensitivity was 68%. Correlation analysis showed a weak correlation between symptoms ranging from 0.07 - 0.41, and no clear clustering of symptoms was detected. We suggest the first diagnostic appendix criteria for genetic and epidemiological studies and tighter criteria for clinical and pathophysiological studies. We encourage further studies of severity and consistency of symptoms.

CONCLUSION

Migraine with cranial autonomic symptoms is prevalent in the general population. Suggested diagnostic appendix criteria are important for future studies of this possible migraine endophenotype.

Red Ear Syndrome and migraine: case report and review of this peculiar association

Introduction: The "Red Ear Syndrome" (RES) is a rare condition (about 100 cases were published in 25 years). It is characterized by episodes of hyperemia of the ear associated with burning pain. Although the association of this syndrome and primary headaches is contemplated in literature, its etiology and treatments are still poorly defined. The aim of this paper is to report a case of RES related to migraine and possible pathophysiologic mechanisms. Case Report: A 31-year-old woman presented with stabbing pain and marked erythema and edema of the right ear accompanied by burning and local hyperhidrosis. These attacks lasted 2 hours on average, and either occurred spontaneously or were associated with migraine without aura. The only means of relief during the attacks was cooling the local with ice. Extensive laboratory-chemical, microbiological, ear-nose-throat, clinical and neurological examinations, magnetic resonance of the brain and cervical spine were unremarkable. Conclusion: Uncertainty about the etiology of this syndrome is an obstacle to treatment. The frequent relationship between RES and migraine suggests that is necessary to investigate the syndrome in migraineurs. Furthermore, new reports about this disorder are important to increase the knowledge of physicians, to reduce the delay in diagnosis and suffering of patients.

Circadian rhythmicity on red ear syndrome in a patient with migraine: A case report

BACKGROUND

Red ear syndrome (RES) was first described by Lance in 1994. It is characterized by recurrent attacks of redness of the ear, accompanied by burning pain, increased temperature, dysesthesia, and nosological relationship with headache.

CASE

We report the case of a 43-year-old woman with migraine who developed RES. Redness episodes occurred at the same time of the day. She had a good therapeutic response to gabapentin.

CONCLUSIONS

To the best of our knowledge, this is the first case of RES in which redness episodes occurred at the same time of the day.

Red ear syndrome in children: Review of literature and report of three cases

BACKGROUND

Red ear syndrome (RES) is a neurological syndrome that is characterized by attacks of redness and pain that is localized in the earlobe, accompanied by a burning sensation, swelling or otalgia. The exact pathophysiology of RES is not known. Several pediatric cases have been described. They show an extreme variability in clinical presentation and therapeutic response, and therefore there are numerous difficulties in the diagnostic-therapeutic approach and in the comprehension of the physiopathology. The goal of this report is to present three clinical cases of red ear syndrome in children. These cases show various characteristics that can give useful indications regarding the differential diagnosis and the pathogenetic mechanisms that are involved, particularly when they are compared with cases published in the literature.

CASE-REPORTS

We report three pediatric RES cases: 1) a boy whose condition offered a typical example of the association that occurs between migraine and RES. 2) a girl with idiopathic RES. 3) a child who suffered RES attacks that showed many similarities with trigeminal autonomic cephalalgias.

CONCLUSION

Our clinical series shows the different ways in which RES can be expressed and they support the reported scientific literature. We suggest that the different forms of RES have a common final autonomic pathogenetic mechanism that is activated by parasympathetic hyperactivity and sympathetic inhibition. The different temporal characteristics, frequency, etc. may depend on the activation of distinct physiopathological modules that are related to the pain circuits, as suggested by the modular theory which describes that groups of neurons are defined as a module, where each module is responsible for a symptom and the individual's headache is defined by the activated modules.

Red Ear: Syndrome or Symptom?

Red ear syndrome (RES) is a rare disorder characterized by attacks of unilateral ear pain during which the ear becomes red. Episodes can occur spontaneously, or be triggered, in most cases, by rubbing or touching the ear. Both duration and frequency are variable. RES has been explained by a dysfunction of cervical spinal nerves (C3 root) and a dysregulation with disinhibition of brainstem trigemino-autonomic circuits, leading to sympathetic inhibition and parasympathetic hyperactivity producing vasodilation. We describe 6 new cases of RES with different characteristics. Although all presented the cardinal symptom of red ear, the headache patterns were suggestive of other primary headaches (migraine or cluster headache). Therapeutic response was obtained when directed to the associated primary headache phenotype, suggesting that RES may be a phenomena associated with different headaches, rather than a syndrome in itself.

A Report of Cranial Autonomic Symptoms in Migraineurs

The presence of cranial autonomic symptoms in migraine is well known and thought to represent activation of the trigeminal parasympathetic reflex pathway similar to trigeminal autonomic cephalalgias. However, studies regarding the prevalence of these symptoms are few. The characteristics of migraineurs with cranial autonomic symptoms and the association of cranial autonomic symptoms with laterality of headache have never been studied in a clinic population. Seventy-eight consecutive subjects with migraine were recruited from the Headache Clinic of the Department of Psychiatry after exclusion of subjects with secondary headache. Their demographic data and detailed history of headache were noted and leading questions were asked regarding cranial autonomic symptoms. χ2 test and Fisher's exact test was used for categorical variables, whereas an independent sample t-test was applied on numerical data. Spearman's correlation was used for correlational analysis of categorical variables. Female subjects (78.2%) outnumbered males and the average duration of illness in the whole sample was 3.81 years. Migraine without aura (53.8%) was the commonest diagnosis, followed by migraine with aura (24.4%). Cranial autonomic symptoms were present in 73.1% of subjects and, commonly, they were ipsilateral to headache. Moreover, strictly unilateral cranial autonomic symptoms were reported by only 32% of patients. The anatomical side of headache did not affect the presence of autonomic symptoms. Those with or without autonomic symptoms did not differ with respect to gender, diagnosis, laterality of headache or associated symptoms except phonophobia, which was more common in subjects with autonomic symptoms ( P = 0.05). Those with autonomic symptoms had longer duration of illness ( P = 0.03) and longer headache episodes ( P = 0.04). In addition, sleep was ineffective in relieving their headache ( P = 0.02). Cranial autonomic symptoms are frequent in migraineurs and are common in subjects with long duration of illness and longer headache episodes. Clinical evidence in the present study suggests that subjects with cranial autonomic symptoms have a hyperactive efferent arm of trigeminal autonomic reflex. The connections of trigeminal nucleus with the locus coeruleus and dorsal raphe nucleus may account for the observed phenotypic differences between the two groups. Further research, however, is required to elucidate the underlying neural mechanisms of cranial autonomic symptoms in migraine.

Neuroimaging brainstem circuitry supporting cardiovagal response to pain: a combined heart rate variability/ultrahigh-field (7 T) functional magnetic resonance imaging study

Central autonomic control nuclei in the brainstem have been difficult to evaluate non-invasively in humans. We applied ultrahigh-field (7 T) functional magnetic resonance imaging (fMRI), and the improved spatial resolution it affords (1.2 mm isotropic), to evaluate putative brainstem nuclei that control and/or sense pain-evoked cardiovagal modulation (high-frequency heart rate variability (HF-HRV) instantaneously estimated through a point-process approach). The time-variant HF-HRV signal was used to guide the general linear model analysis of neuroimaging data. Sustained (6 min) pain stimulation reduced cardiovagal modulation, with the most prominent reduction evident in the first 2 min. Brainstem nuclei associated with pain-evoked HF-HRV reduction were previously implicated in both autonomic regulation and pain processing. Specifically, clusters consistent with the rostral ventromedial medulla, ventral nucleus reticularis (Rt)/nucleus ambiguus (NAmb) and pontine nuclei (Pn) were found when contrasting sustained pain versus rest. Analysis of the initial 2-min period identified Rt/NAmb and Pn, in addition to clusters consistent with the dorsal motor nucleus of the vagus/nucleus of the solitary tract and locus coeruleus. Combining high spatial resolution fMRI and high temporal resolution HF-HRV allowed for a non-invasive characterization of brainstem nuclei, suggesting that nociceptive afference induces pain-processing brainstem nuclei to function in concert with known premotor autonomic nuclei in order to affect the cardiovagal response to pain.

Red ear syndrome: literature review and a pediatric case report

Red ear syndrome (RES) is characterized by recurrent unilateral or bilateral painful attacks of the external ear, accompanied by ear redness, burning, or warmth. Proposed etiologies of this rare condition include dysregulation of sympathetic outflow, upper cervical pathology, glossopharyngeal and trigeminal neuralgia, TMJ dysfunction, thalamic syndrome, and primary headache syndromes. Idiopathic cases also exist in the literature. Pediatric cases are particularly rare and more commonly associated with migraine. Given the various potential etiologies, no single treatment is effective in all cases. This paper summarizes the current understanding and management of RES, and describes a case of idiopathic pediatric RES.

Migraine and cranial autonomic symptoms in children and adolescents: a clinical study

The frequency of cranial autonomic symptoms in children affected by primary headaches is uncertain. The aim of our study was to estimate the frequency of symptoms in pediatric headaches and correlate it with main migraine characteristics. A questionnaire investigating the presence of cranial autonomic symptoms was administered to all children with primary headache for 2 years. A total of 230 children with primary headache (105 males, 125 females) were included. Two hundred two children were affected by migraine and 28 (12.2%) by other primary headaches. Cranial autonomic symptoms were significantly complained by migraineurs (55% vs. 17.8%) (P < .001) and by children with higher frequency of migraine attacks (odds ratio = 2.6, confidence interval = 1.4-4.7, P = .001). Our findings show that cranial autonomic symptoms are rather common during pediatric migraine attacks. The association between cranial autonomic symptoms and higher frequency of attacks might suggest the role of the trigeminal-autonomic reflex in migraine pathophysiology.

Red ear syndrome precipitated by a dietary trigger: a case report

Introduction

Red ear syndrome is a rare condition characterized by episodic attacks of erythema of the ear accompanied by burning ear pain. Symptoms are brought on by touch, exertion, heat or cold, stress, neck movements and washing or brushing of hair. Diagnosis and treatment of this condition are challenging. The case we report here involves a woman whose symptoms were brought on by a dietary trigger: orange juice as well as stress, causing significant physical and psychological morbidity. Avoidance of triggers resulted in symptomatic improvement.

Case presentation

A 22-year-old Caucasian woman who was a student presented twice to our department with evolving symptoms, the first time with hyperacusis (abnormal sound sensitivity arising from within the auditory system to sounds of moderate volume), intermittent right tinnitus and subjective hearing difficulties. She presented five years later with highly distressing episodes of erythematous ears, which were associated with burning pain around the ear and temporal areas, and intolerance to noise. After keeping a symptom diary, she identified orange juice and stress as triggers of her symptoms. No local head and neck pathology was present. Investigations and imaging were negative. Avoidance of triggers led to great symptomatic improvement. To the best of our knowledge, dietary triggers have not previously been reported as a trigger for this syndrome. This case shows a direct temporal link to a dietary trigger and supports a primary pathogenesis. Recognition and management of primary headache disorder and simple dietary and lifestyle changes brought about symptomatic relief.

Conclusion

Red ear syndrome is a little-known clinical syndrome of unknown etiology and management. To the best of our knowledge, our present case report is the first to describe primary red ear syndrome triggered by orange juice. Clinical benefit derived from avoidance of this trigger, which is already known to precipitate migraines, gives some insight into the pathogenesis of red ear syndrome.

The red ear syndrome

Red Ear Syndrome (RES) is a very rare disorder, with approximately 100 published cases in the medical literature. Red ear (RE) episodes are characterised by unilateral or bilateral attacks of paroxysmal burning sensations and reddening of the external ear. The duration of these episodes ranges from a few seconds to several hours. The attacks occur with a frequency ranging from several a day to a few per year. Episodes can occur spontaneously or be triggered, most frequently by rubbing or touching the ear, heat or cold, chewing, brushing of the hair, neck movements or exertion. Early-onset idiopathic RES seems to be associated with migraine, whereas late-onset idiopathic forms have been reported in association with trigeminal autonomic cephalalgias (TACs). Secondary forms of RES occur with upper cervical spine disorders or temporo-mandibular joint dysfunction. RES is regarded refractory to medical treatments, although some migraine preventative treatments have shown moderate benefit mainly in patients with migraine-related attacks. The pathophysiology of RES is still unclear but several hypotheses involving peripheral or central nervous system mechanisms have been proposed.

Primary red ear syndrome associated with cochleo-vestibular symptomatology: A paediatric case report

Background

Red ear syndrome (RES), first described by Lance in 1996 in an adult series, may be primary or associated with headache syndromes, upper cervical disorders or vascular anomalies. Clinically the disease is characterised by recurrent episodes of reddening and burning pain in the auricle, usually elicited by different triggers. The prevalence of RES in the paediatric age group remains poorly understood. Several therapeutic approaches have been tried with heterogeneous clinical response.

Case results

We report a paediatric patient suffering from primary RES associated with debilitating cochleo-vestibular symptomatology causing severe discomfort. Three years after the disease onset, the patient also developed headache, with clinical features of migraine.

Discussion

The temporal and spatial association could suggest shared pathogenetic features between neurological (cochleo-vestibular) and vascular (red and burning ear) symptomatology, likely related to trigeminal autonomic reflex activation, although further studies are required for full comprehension of RES pathogenesis.

SUNA and red ear syndrome: a new association and pathophysiological considerations

Red ear syndrome (RES) is characterised by attacks of unilateral or bilateral burning ear pain associated with erythema. Primary and secondary forms have been described. Primary RES appears to have a frequent association with primary headaches especially migraine. Here, we describe the case of a woman with short-lasting unilateral neuralgiform attacks with cranial autonomic symptoms (SUNA) and recurrent episodes of ipsilateral red ear triggerable by cutaneous stimulation. Lamotrigine was beneficial for her SUNA but not for the RES. Both these disorders are extremely rare therefore their coexistence in the same individual may suggest similar pathophysiological mechanisms rather than a chance association.

Red ear syndrome: A review of all published cases (1996–2010)

Background

Red ear syndrome is characterised by episodic unilateral erythema of the ear associated with pain and burning sensation.

Patients and methods

We describe the case of a young woman with daily, frequent, recurrent episodes of red ear syndrome in the absence of any structural lesions, primary headache disorder or obvious triggers. We review all previously described cases and discuss postulated mechanisms for this syndrome.

Conclusions

The exact cause of this rare headache disorder remains unknown and treatment options vary considerably.

Comparison of clinical characteristics of migraine and tension type headache

CONTEXT

Migraine and tension type headache (TTH) are two most common types of primary headaches. Though the International Classification of Headache Disorders-2 (ICHD-2) describes the diagnostic criteria, even then in clinical practice, patients may not respect these boundaries resulting in the difficulty in diagnosis of these pains.

MATERIALS AND METHODS

This cross-sectional study involved 50 subjects in each of the two groups - migraine and TTH - after screening for the inclusion and exclusion criteria. Diagnosis was made according to the ICHD-2 criteria. Their clinical history was taken in detail and noted in a semi-structured performa. They were examined for the presence of a number of factors like pericranial tenderness and muscle parafunction. Statistical analysis was done with the help of SPSS v 11.0. To compare the non-parametric issues, chi-square test was run and continuous variables were analyzed using independent sample t test.

RESULTS

In general, migraineurs had progressive illness (χ(2)=9.45; P=0.002) with increasing severity (χ(2)=21.86; P<0.001), frequency (χ(2)=8.5; P=0.04) and duration of each headache episode (χ(2)=4.45; P=0.03) as compared to TTH subjects. Along with the headache, they more commonly suffered orthostatic pre-syncope (χ(2)=19.94; P<0.001), palpitations (42%vs.18% among TTH patients; χ(2)=6.87; P=0.009), nausea and vomiting (68% vs. 6% in TTH; χ(2)=41.22; P<0.001, and 38% vs. none in TTH; χ(2)=23.45, P<0.001, respectively), phonophobia (χ(2)=44.98; P<0.001), photophobia (χ(2)=46.53; P<0.001), and osmophobia (χ(2)=15.94; P<0.001). Their pain tended to be aggravated by head bending (χ(2)=50.17; P<0.001) and exercise (χ(2)=11.41; P<0.001). Analgesics were more likely to relieve pain in migraineurs (χ(2)=21.16; P<0.001). In addition, post-headache lethargy was more frequent among the migraineurs (χ(2)=22.01; P<0.001). On the other hand, stressful situations used to trigger TTH (χ(2)=9.33; P=0.002) and muscle parafunction was more common in TTH patients (46% vs. 20%; χ(2)=7.64; P=0.006). All the cranial autonomic symptoms were more common in migraineurs as compared to TTH subjects (conjunctival injection: χ(2)=10.74, P=0.001; lacrimation: χ(2)=17.82, P<0.001; periorbital swelling: χ(2)=23.45, P<0.001; and nasal symptoms: χ(2)=6.38, P=0.01).

CONCLUSION

A number of symptoms that are presently not included in the ICHD-2 classification may help in differe-ntiating the migraine from the TTH.

Prevalence of red ear syndrome in juvenile primary headaches

BACKGROUND

Previous studies have suggested a relationship between 'red ear syndrome' (RES) and pediatric migraine. Aims of this study were (i) to assess the frequency, specificity and sensitivity of RES in a population of pediatric migraineurs and (ii) to establish the pathophysiological mechanisms of RES associated with migraine.

METHODS AND RESULTS

A total of 226 children suffering from headache (aged 4-17 years) were enrolled. One hundred and seventy-two (76.4%) were affected by migraine, the remaining 54 (23.6%) by other primary headaches. RES was followed significantly more frequently by migraine (23.3%; p < .0001), and was characterized by high specificity and positive predictive value (96.3 and 95.3%, respectively). According to the univariate statistical analysis, RES showed a statistically significant association with male gender, throbbing quality of the pain, vomiting and phonophobia. It was confirmed by a multivariate stepwise logistic regression model only for the throbbing quality of the pain, vomiting and male gender.

CONCLUSIONS

Our study showed that (i) in children, RES is a highly specific sign for migraine. In addition, the evidence of an association of RES with some migraine features partially provoked by the parasympathetic system supports the hypothesis of a shared pathophysiological background (e.g. via the activation of the trigeminal-autonomic reflex).

Positional cluster-like headache. A case report of a neurovascular compression between the third cervical root and the vertebral artery

Symptomatic cluster-like headaches have been described with lesions of the trigeminal and parasympathetic systems. Here, we report the case of a 44-year-old woman with continuous auricular pain and a positional cluster-like headache associated with red ear syndrome. Clinical data and morphological investigations raised the hypothesis of a neurovascular compression between the C3 root and vertebral artery. Neurosurgical exploration found a fibrosis surrounding both the C3 root and the vertebral artery. The excellent outcome after microvascular cervical decompression suggests a causal relationship between the cluster-like headache and the vertebral constraint on the C3 root.

The Almirall European Headache Awards 2009

The Almirall European Headache Awards (AEHA) were organized in conjunction with the European Headache Federation. The awards were held in 2009, aiming to share clinical experience and best practice in headache-related disease management. 56 unusual and challenging cases of headache from 5 European countries (Belgium, France, Italy, Portugal and Spain) were judged by a Scientific Committee including expert representatives from participating countries, acting as reviewers. Three cases were selected from each country. The 15 resulting cases were presented to the Scientific Committee in Madrid, Spain in November 2009 and awards were given to the top 5 presentations. This article presents details of these cases, including the award winning entries. They have been categorized into four main groups: (a) headaches in rare syndromes; (b) secondary headaches to infectious/autoimmune causes or post-trauma/mass occupation; (c) headache in unresolved cases; and (d) other relevant cases. First prize was awarded to a case involving a 55-year-old male with familial thrombocytopenia and a unilateral neuralgiform headache secondary to trigeminal vascular contact, and which was successfully treated with carbamazepine. Conclusions from the meeting include: rare syndromes do occur and require appropriate treatment to improve outcomes; concomitant diseases may impair adequate diagnosis and should be investigated; physicians should be cautious and treat possible serious underlying disease, whilst accurately clarifying the correct diagnosis; neurological examination and complementary tests may be required; consideration should be given to possible rare medication events; and some cases may remain without a clear cause or diagnosis and symptoms should be treated whilst investigations continue.

Paroxysmal Hemicrania in Children—Symptoms, Diagnostic Criteria, Therapy and Outcome

Whereas paroxysmal hemicrania (PH) is studied extensively in adults, even case reports of PH in children are rare. We present the first prospective follow-up study on PH in children. Our aim was to investigate whether differences exist between paediatric and adult patients. We assessed all children with chronic headache who were referred to our paediatric out-patient pain clinic within 3 years based on interviews and validated questionnaires. Among 628 patients we found five children with PH (0.8%) and three with probable PH (0.5%), in total 1.3%. Pain characteristics, autonomic symptoms and treatment response to indomethacin were similar to adult PH patients. Our results demonstrate that the International Headache Society classification of PH is also applicable to children. We suspect that PH has been underdiagnosed in children and therefore suboptimally treated thus far.

Pathology of the trigeminal nerve

Imaging of the trigeminal nerve requires a thorough understanding of its anatomy and function, clinical symptoms related to malfunction, and its key pathologies. Because of the nerve's long course from the brainstem nuclei to the peripheral branches, MR imaging and CT studies have to cover a large anatomic area while providing high-resolution images. Although MR imaging has almost completely replaced CT as the diagnostic modality of choice for investigating trigeminal neuropathy, CT still plays a role in the assessment of skull base foramina and facial skeleton. In this article, the clinical, radiologic, and pathologic features of the most common conditions causing trigeminal nerve dysfunction at each specific anatomic level are discussed.

Red ear syndrome

The red ear syndrome is a rare syndrome originally described by Lance in 1994. It involves pain in and around the ear and associated autonomic phenomena, the most significant of which is cutaneous erythema of the ear ipsilateral to the pain and obvious to the patient and examiner during the attack. It may well represent an auriculo-autonomic cephalgia and/or be part of the group of disorders recognized as trigeminal autonomic cephalalgias. As a syndrome, it still lacks specificity in regard to etiology, mechanisms, and treatment but is important to recognize clinically because of its associations.

Case studies of uncommon headaches

The following interesting and uncommon headache disorders are presented through case studies: exploding head syndrome, hypnic headache, neck-tongue syndrome, "Alice in Wonderland" syndrome, nummular headache, red ear syndrome, burning mouth syndrome, spontaneous intracranial hypotension syndrome, and cardiac cephalalgia.

Facial pain: clinical differential diagnosis

Differential diagnosis of pain in the face as the presenting complaint can be difficult. We propose an approach based on history and neurological examination, which allows a working diagnosis to be made at the bedside, including aetiological hypotheses, leading to a choice of investigations. Neuralgias are characterised by stabs of short lasting, lancinating pain, and, although neuralgias are often primary, imaging may be needed to exclude symptomatic forms. Facial pain with cranial nerve symptoms and signs is almost exclusively of secondary origin and requires urgent examination. Facial pain with focal autonomic signs is mostly primary and belongs to the group of the idiopathic trigeminal autonomic cephalalgias, but can occasionally be secondary. Pure facial pain is most often due to sinusitis and the chewing apparatus, but also a multitude of other causes. The pain can also be idiopathic. Imaging as well as non-neurological specialist assessment is often necessary in these cases.

Chronic paroxysmal hemicrania in a 3-year, 10-month-old female

This is the report of a 3-year, 10-month-old female with classical symptoms of chronic paroxysmal hemicrania and favorable response to indomethacin therapy. The patient was admitted because of frequent episodes of severe unilateral headaches during the day and nighttime as well as agitation. During the episodes, she complained of severe pains on the left orbital and supraorbital region. Subsequent lacrimation from the left eye was also documented. Initially, focal epileptic attack was diagnosed and during the following 10 months several antiepileptic drugs were used without effect. After 10 months, chronic paroxysmal hemicrania was diagnosed because of the typical symptoms along with a favorable response to indomethacin therapy.
