Cluster headache associated with moyamoya

Evaluation and treatment of headache associated with moyamoya disease - a narrative review

BACKGROUND

Headache in patients with moyamoya disease is an under-addressed topic in the medical literature. Delay in the diagnosis of moyamoya disease or inappropriate treatment of headache could lead to devastating cerebrovascular outcome. With the evolving understanding of moyamoya disease, migraine pathophysiology, and various migraine-specific medications that have become available, it is crucial to provide an updated overview on this topic.

METHODS

We searched PubMed for keywords including moyamoya disease, moyamoya syndrome, headache in moyamoya, surgical revascularization, surgical bypass, migraine and moyamoya, and calcitonin gene-related peptide (CGRP). We summarized the literature and provide a comprehensive review of the headache presentation, possible mechanisms, the impact of various surgical revascularizations on headache in patients with moyamoya disease, and the medical management of headache incorporating novel migraine-specific treatments.Results and conclusion: The most common headache phenotype is migraine; tension-type headache, hemiplegic migraine, and cluster headache have also been reported. Most patients experience improvement of headache after surgical revascularization, though some patients report worsening, or new-onset headache after surgery. Given the complexity of moyamoya disease, careful consideration of different types of medical therapy for headache is necessary to improve the quality of life while not increasing the risk of adverse cerebrovascular events. More prospective studies are warranted to better understand and manage headache in patients with moyamoya disease.

Cluster headache due to structural lesions: A systematic review of published cases

BACKGROUND

Cluster headache (CH) is a severe incapacitating headache disorder. By definition, its diagnosis must exclude possible underlying structural conditions.

AIM

To review available information on CLH caused by structural lesions and to provide better guides in the distinguishing process and to ensure that there is not a potentially treatable structural lesion.

METHODS

We conducted a systematic review of 77 published cases of symptomatic CH and cluster-like headache (CLH) in PubMed and Google Scholar databases.

RESULTS

Structural pathologies associated with CH were vascular (37.7%), tumoral (32.5%) and inflammatory (27.2%). Brain mass-like lesions (tumoural and inflammatory) were the most common diseases (28.6%), among which 77.3% lesions were at the suprasellar (pituitary) region. Cases of secondary CH related to sinusitis rose dramatically, occupying 19.5%. The third most common disease was internal carotid artery dissection, accounting for 14.3%. Atypical clinical features raise an early suspicion of a secondary cause: Late age at onset and eye and retroorbital pains were common conditions requiring careful evaluation and were present in at least one-third of cases. Abnormal neurological examination was the most significant red flag for impaired cranial nerves. CLH patients may be responsive to typical CH treatments; therefore, the treatment response is not specific. CLH can be triggered by contralateral structural pathologies. CLH associated with sinusitis and cerebral venous thrombosis required more attention.

CONCLUSION

Since secondary headache could perfectly mimick primary CH, neuroimaging should be conducted in patients in whom primary and secondary headaches are suspected. Cerebral magnetic resonance imaging scans is the diagnostic management of choice, and further examinations include vessel imaging with contrast agents and dedicated scans focusing on specific cerebral areas (sinuses, ocular and sellar regions). Neuroimaging is as necessary at follow-up visits as at the first observation.

Features and diversity of symptoms of moyamoya disease in adolescents: A cluster analysis

AIMS

The purpose of this study is to explore the symptoms experienced by adolescents with moyamoya disease and to identify the characteristics of each symptom cluster associated with moyamoya disease.

DESIGN

A retrospective and descriptive design, which is a secondary data analysis study based on electronic medical record data from hospitals.

METHODS

To assess the symptoms associated with moyamoya disease, a qualitative study was conducted on 12 adolescents, 12 caregivers and 12 experts on moyamoya disease. According to a qualitative study, 12 main symptoms (limb weakness, numbness, pins and needles, difficulty in speech, blurred vision, facial paralysis, hand tremors, involuntary movements, convulsions, dizziness, nausea/vomiting and headaches) were selected. Data were collected around these symptoms. The data collection was carried out through the Electronic Medical Record (EMR) data of 303 adolescents aged 13-19 who were diagnosed with moyamoya disease (ICD 10 Code: I67.5) between January 2010-December 2019 in a hospital in Seoul, South Korea. Cluster analysis was applied to identify symptom clusters with the hierarchical cluster agglomerative approach. We used the log-likelihood distance to measure the similarity of variables. Proximity between groups of variables was measured using the two-step method.

RESULTS

The physical symptoms experienced by adolescents with moyamoya disease were 'limb weakness' - the most common - followed by a 'headache,' 'difficulty in speech,' and 'nausea/vomiting.' A total of five symptom clusters were derived: cluster 1 was characterized by 'limb weakness'; cluster 2 participants were asymptomatic or experienced 'convulsions'; cluster 3 experienced 'difficulty in speech' and 'facial paralysis'; cluster 4 is prone to 'dizziness' and 'pins and needles'; and cluster 5 displays 'headaches' and 'nausea/vomiting'.

CONCLUSION

This study offers a multidimensional approach for identifying differences in clinical symptoms of moyamoya disease among adolescents.

IMPACT

These results will help provide interventions concerning the characteristics of the symptoms of moyamoya disease among adolescents.

Paroxysmal hemicrania masquerading as a stroke in an elderly gentleman: case report

Background

Paroxysmal hemicrania has not been associated with ipsilateral weakness, loss of sensation and Horner’s syndrome. This report is the first of its kind documented in literature.

Case presentation

This was an elderly, sixty-five-year-old Chinese male who presented with a headache fulfilling criteria of paroxysmal hemicrania and was found to have signs of ipsilateral conjunctival injection, Horner’s syndrome, weakness and loss of sensation; with resolution of the patient’s physical signs after relief of the headache. Brain magnetic resonance imaging did not show any strokes or other headache mimics. The patient had a marked response to indomethacin and a decrease of headache intensity and frequency with indomethacin prophylaxis.

Conclusions

Paroxysmal hemicrania has joined the list of stroke chameleons and that it would be one of the differentials in a patient with hemiplegia, hemisensory loss, autonomic signs and severe headache. It suggests that paroxysmal hemicrania in the elderly present atypically.

Association of Superficial Temporal Artery Dilatation with Headache After Revascularization in Adult Moyamoya Disease

BACKGROUND

The underlying mechanisms of headache in adult moyamoya disease (MMD) are not clear. The aim of this study is to clarify the factors that are associated with headache in adult patients with MMD after superficial temporal artery (STA)-middle cerebral artery (MCA) anastomosis.

METHODS

We retrospectively analyzed the cases of 68 adult patients with MMD: 30 with surgery and 38 without surgery. Each STA-MCA anastomosis was performed by the standard technique. Magnetic resonance angiography (MRA) and single photon emission computed tomography were performed perioperatively. We stratified the intensity and frequency of the patients' headaches into 4 ranks. Pre- and postoperative STA diameters were retrospectively measured on digital subtraction angiography (DSA) and/or MRA.

RESULTS

In the surgery group, preoperative regional cerebral blood flow (rCBF) laterality and a postoperative rCBF increase >20% showed no significant difference between the patients with and without headache with a univariate analysis. The postoperative STA diameters of the distal branch (DSA) and main trunk (DSA/MRA) in the patients with headache were significantly larger than those of the patients without headache. The rate of postoperative increase of the STA diameters of the distal branch/main trunk was also significantly higher in the patients with headache than those without headache. A multivariate analysis showed that the standard regression coefficient β for sex, a >20% increase of postoperative rCBF, and the increase rate of the STA diameter of the distal branch shown by DSA was 0.37, 0.54, and 0.56, respectively.

CONCLUSIONS

The results of our analyses revealed that aside from ischemia, the postoperative increase rate of the STA may be a candidate reason for headache, especially in adult patients with MMD.

Symptomatic Trigeminal Autonomic Cephalalgias

Trigeminal autonomic cephalalgias (TACs) are primary headache syndromes that share some clinical features such as a trigeminal distribution of the pain and accompanying ipsilateral autonomic symptoms. By definition, no underlying structural lesion for the phenotype is found. There are, however, many descriptions in the literature of patients with structural lesions causing symptoms that are indistinguishable from those of idiopathic TACs. In this article, we review the recent insights in symptomatic TACs by comparing and categorizing newly published cases. We confirm that symptomatic TACs can have typical phenotypes. It is of crucial importance to identify symptomatic TACs, as the underlying cause will influence treatment and outcome. Our update focuses on when a structural lesion should be sought.

Symptomatic cluster headache: a review of 63 cases

Cluster headache is a primary headache by definition not caused by any known underlying structural pathology. Symptomatic cases have been described, for example tumours, dissections and infections, but a causal relationship between the underlying lesion and the headache is difficult to determine in many cases. The proper diagnostic evaluation of cluster headache is an issue unresolved. The literature has been reviewed for symptomatic cluster headache or cluster headache-like cases in which causality was likely. The review also attempted to identify clinical predictors of underlying lesions in order to formulate guidelines for neuroimaging. Sixty-three cluster headache or "cluster headache-like"/"cluster-like headache" cases in the literature were identified which were associated with an underlying lesion. A majority of the cases had a non-typical presentation that is atypical symptomatology and abnormal examination (including Horner’s syndrome). A striking finding in this appraisal was that a significant proportion of CH cases were secondary to diseases of the pituitary gland or pituitary region. Another notable finding was that a proportion of cluster headache cases were associated with arterial dissection. Even typical cluster headaches can be caused by structural lesions and the response to typical cluster headache treatments does not exclude a secondary form. It is difficult to draw definitive conclusions from this retrospective review of case reports especially considering the size of the material. However, based on this review, I suggest that neuroimaging, preferably contrast-enhanced magnetic resonance imaging/magnetic resonance angiography should be undertaken in patients with atypical symptomatology, late onset, abnormal examination (including Horner’s syndrome), or those resistant to the appropriate medical treatment. The decision to perform magnetic resonance imaging in cases of typical cluster headache remains a matter of medical art.

Cluster-like headache secondary to parasagittal hemangiopericytoma

We describe an original case of cluster-like headache CLH) revealing a parasagittal tumor invading the superior sagittal sinus (SSS). Resection of the tumor (hemangiopericytoma) allowed the re-permeabilization of the SSS and was followed by the complete disappearance of CLH. Several mechanisms including obstruction of the SSS, hypervascularization with arterio-veinous shunt, and overflow in the cavernous sinus might explain the symptoms.

Effective surgical revascularization improves cerebral hemodynamics and resolves headache in pediatric Moyamoya disease

BACKGROUND

Headache is one of the major clinical presentations in pediatric Moyamoya disease. However, the clinical features and underlying mechanisms are not fully understood. This study aimed to clarify the clinical feature of headache in pediatric Moyamoya disease and the effect of surgical revascularization.

METHODS

This study included 29 pediatric patients who underwent superficial temporal artery to middle cerebral artery (STA-MCA) anastomosis and indirect bypass for Moyamoya disease. Their medical records were precisely evaluated to identify the clinical features of their headache. The findings on magnetic resonance imaging, positron emission tomography, and single-photon emission computed tomography also were analyzed.

RESULTS

Preoperative headache was documented in 11 (38%) of 29 patients. The majority of them complained of severe headache in the frontal or temporal region in the morning. Headache was significantly related to more advanced disease stage and to the decreases in cerebral blood flow and its reactivity to acetazolamide. Surgical revascularization completely resolved headache in all 11 patients.

CONCLUSIONS

These findings strongly suggest that disturbed cerebral hemodynamics may play key roles in developing severe headache in pediatric Moyamoya disease. STA-MCA anastomosis and encephalo-duro-myo-arterio-pericranial synangiosis may be effective procedures to rapidly resolve headache by widely supplying collateral blood flow to the operated hemispheres.

Headache associated with moyamoya disease: a case story and literature review

Headache associated with moyamoya disease (HAMD) is common in moyamoya disease. However, the characteristics and classification of HAMD are largely unknown. We present a case of a 39-year-old woman with HAMD. To characterize and classify the features of this syndrome, the patient was asked to complete a 4-month diagnostic headache diary. There was a total of 15 ictal days. All episodes were without aura. The headache was more commonly pressing (10/15), mild to moderate in severity (14/15), unchanged by physical activity (11/15), and associated with photophobia (10/15). The International Headache Society Classification was utilized to determine that eight episodes met criteria for probable migraine without aura, while seven episodes met criteria for probable frequent episodic tension-type headache. We identified four other case reports of HAMD with partial descriptions of the characteristics. When combined with our patient, the median age was 34 years old (range 6-49, SD 16). Four were female, while the patient with cluster headache was male. The median time from headache onset to diagnosis with moyamoya disease was 9.5 months (range 0-192, SD 88.0). Headaches were described as migraine with aura in two of five cases, hemiplegic migraine in one of five, and cluster headache in one of five. The highest intensity was described as severe in three of three cases, in which headache intensity was reported. Meanwhile, nausea, vomiting, and photophobia were present in two of three cases, where these features were reported, while nausea without vomiting was seen in one of three cases. In all five cases, patients had other neurological symptoms, such as paresis, seizures, visual disturbances, dysarthria, allodynia, ptosis, and unilateral restless leg syndrome. In conclusion, HAMD can present as migraine without aura. It can be the first presenting symptom of moyamoya disease. The headache features are not diagnostic; hence, early neurovascular imaging should be considered in patients with new onset, refractory migraine-like headache, especially in the setting of other neurological symptoms to exclude underlying moyamoya disease. Further reports using headache diaries are needed to better characterize HAMD as well as to determine whether headache with tension-type features is also part of this condition.

Moyamoya: to cut or not to cut is not the only question. A paediatric neurologist's perspective

The paediatric neurologist is usually the clinician who makes the diagnosis of moyamoya in children, yet most of the debate in the literature has focused on surgical management of the condition. Semantic confusion and variable use of the term among neuroradiologists continues to be unhelpful. Increasing recognition of moyamoya, for example in sickle cell disease, and the publication of clinical guidelines encouraging referral for surgical evaluation highlight the need to identify and engage with management of the condition. In practical terms, the most frequent management issues for the paediatric neurologist, other than when to refer for surgery, are headache, hypertension, and the concern of the family that other children might be affected. These issues are discussed in the context of the available literature, and areas in which there is a need for research and consensus are identified.

Neuroimaging in trigeminal autonomic cephalgias: when, how, and of what?

PURPOSE OF REVIEW

Trigeminal autonomic cephalgias (TACs) are characterized by frequent, short-lasting headache attacks with ipsilateral facial autonomic features. They include cluster headache, paroxysmal hemicrania, and short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing. The pathogenesis of TACs is largely unknown, but many case reports in the literature suggest that TACs are secondary to structural lesions. Thus, the question arises whether TAC patients should undergo neuroimaging. Here, we review the recent literature on secondary TACs and attempt to formulate guidelines for neuroimaging.

RECENT FINDINGS

Recently, we published two reviews of, in total, 33 case reports of patients with a secondary TAC or TAC-like syndrome. Since then, 23 additional cases have been published. Here, we provide a summary of these 56 case reports. TACs were found to be associated with a wide range of both intracranial and extracranial neurovascular and structural lesions. We could not identify a 'typical' clinical warning profile for secondary TACs as these patients could present with clinical features that are entirely characteristic of a TAC, including alternating attack and attack-free periods, and excellent response to TAC-specific treatments.

SUMMARY

Even clinically typical TACs can be caused by structural lesions. There are no 'typical' warning signs or symptoms. Neuroimaging should be considered in all patients with TAC or TAC-like syndromes, notably in those with atypical presentation. Depending on the degree of suspicion, additional imaging should be considered assessing intracranial and cervical vasculature, and the sellar and paranasal region.
