ABSTRACT
Calcitonin gene-related peptide (CGRP) inhibitors, in the form of injectable monoclonal antibodies, are a newer class of drugs for the prevention of migraine headaches. In clinical trials, they have been found to be effective with good tolerance and few adverse effects. Alopecia has been increasingly noted as a post-marketing event associated with CGRP inhibitor injectables. Of the case reports available on this topic, alopecia has commonly been localised to the scalp and associated with erenumab use; however, not as much has been reported for fremanezumab nor for injection site-related alopecia. We report an occurrence of persistent lower extremity localised injection site alopecia in a patient within our headache clinic who used fremanezumab. The possible mechanism of alopecia may be related to the failure of hair follicle immune privilege in the absence of CGRP immunomodulatory effects.

Headache and neurological deficits with cerebrospinal fluid (CSF) lymphocytosis (HaNDL) is a rare condition characterised by recurrent episodes of headache and transient neurological deficits. This case report presents a young patient initially diagnosed with hemiplegic migraine, having a normal brain CT, with focal cerebral perfusion mismatch not restricted to a single vascular territory on CT angiography. Brain MRI revealed a cytotoxic lesion of the splenium in the corpus callosum (CLOCC), a feature also reported in migraine. However, recurrent headaches with neurological deficits prompted further investigations with CSF analysis and brain MRI, confirming HaNDL and demonstrating reversibility of CLOCC. Recognising HaNDL as a differential diagnosis is essential in patients with recurrent headaches with focal neurological deficits, given the differences in therapeutic approach. The relationship between migraine and HaNDL is not fully understood, but they may share a pathophysiological link. Awareness of this is crucial for accurate diagnosis.

Spontaneous intracranial hypotension (SIH) is a condition characterised by postural headaches due to low cerebrospinal fluid (CSF) pressure, often stemming from CSF leakage. Diagnosis poses a significant challenge, and the therapeutic approach encompasses both conservative measures and operative interventions, such as the epidural blood patch (EBP). However, EBP carries the potential risk of inducing rebound intracranial hypertension (RIH), subsequently leading to high-pressure headaches. We present a case wherein RIH following EBP was effectively managed through the implementation of an external ventricular drain (EVD) aimed at reducing CSF pressure. The patient improved significantly, underscoring the potential utility, if not necessity, of EVD in carefully selected cases, highlighting the imperative for further research to enhance the management of SIH and optimise EBP-related complications.

We report the case of a middle-aged hypertensive woman presenting to the neurology department with short-lasting episodic headaches for 4 years. She was initially diagnosed and treated with cluster headaches for one year. Following this, she presented with right lower limb arterial claudication. Arterial Doppler of lower limbs showed thrombosis of the bilateral common femoral arteries. Further computed tomography (CT) angiogram of the lower limbs confirmed extensive arterial thrombosis in bilateral lower limbs. The CT angiogram incidentally detected a left adrenal lesion. She had elevated urinary vanillylmandelic Acid and 24-hour metanephrines suggesting the presence of a pheochromocytoma. She was initially medically managed and later underwent left open adrenalectomy. Histopathology examination of the sections proved pheochromocytoma. Postsurgery, the patient's symptoms improved remarkably. This case highlights the importance of diagnosing pheochromocytoma when you encounter a patient with refractory short-lasting headaches, hypertension and hypercoagulability.

Serotonin syndrome (SS) is an iatrogenic, drug-induced clinical syndrome caused by an increase in the intrasynaptic concentration of serotonin. Serotonin plays a significant role in the pathophysiology of migraines. Upregulation of 5-HT2A receptors is found in medication-overuse headache (MOH). Several migraine medications, both preventative and abortive drugs, act on serotonin receptors. We report two patients with chronic migraine who developed MOH. Besides headache, patients had frequent attacks of dizziness, restlessness, irritability, insomnia, excessive sweating, abdominal discomforts and tremors. These symptoms were suggestive of withdrawal headache. However, on physical examinations, we elicited hyperreflexia, hypertonia, clonus, tachycardia, hypertension, mydriasis and hyperactive bowel sound. Both patients also met the criteria for SS. Cyproheptadine was started. All features, including headaches, got better after cyproheptadine administration within 24 hours. In 7 days, there was practically total improvement. Both patients continued to take cyproheptadine as a preventative medicine, and migraine frequency was under control.

We describe a case of infiltrative optic neuropathy with hypertrophic pachymeningitis noted on MRI of the brain, presenting a diagnostic dilemma with a wide variety of differential diagnoses to consider. Our patient is a middle-aged woman with a 20-year history of migranous-sounding headaches who was incidentally found to have worsening vision in her left eye during a routine driving test visual acuity check. Neurological examination revealed a left grade III relative afferent pupillary defect and a central scotoma with red desaturation. Subsequent MRI of her brain and anterior visual pathway revealed features suggestive of an infiltrative left optic neuropathy with hypertrophic pachymeningitis. An extended workup including diagnostic lumbar puncture and blood tests for possible autoimmune, infective and neoplastic causes proved unyielding. Eventually, an endoscopic transsphenoidal biopsy helped to clinch the diagnosis of a (meningothelial subtype) WHO grade 1 meningioma as the cause of her clinical and radiological presentation.

We present a case of a woman in her 30s with relapsing-remitting multiple sclerosis, treated with natalizumab, who developed ophthalmic varicella zoster virus (VZV) infection, with subsequent vasculopathy causing cerebral ischaemic lesions. She was treated with acyclovir, prednisolone and acetylsalicylic acid and fully recovered. VZV vasculopathy is associated with stroke and immunomodulating treatments may increase the risks of these adverse events. To date, nine VZV-related vasculopathy cases in patients treated with natalizumab have been reported in English literature and are summarised in this paper. Although rare, VZV intracerebral vasculopathy is an important differential diagnosis in patients with unexplained new-onset neurological symptoms after a herpes zoster infection. Treatment guidelines for VZV vasculopathy and for continuing treatment of multiple sclerosis after such an event are currently not established.

Cerebral venous thrombosis is a rare condition, with identified and described risk factors mainly associated with prothrombotic states, with a wide variety of symptomatology based on the site affected, the most common being intracranial hypertensive syndrome, focal or encephalopathy. Cortical veins of the superficial system are among the least frequently affected veins. The following describes a case of painful facial symptoms progressing to a focal syndrome associated with a history of chronic oral contraceptive use, with thrombosis of vein of Trolard detected and successfully treated with oral anticoagulants.

A boy in his middle childhood presented with intermittent episodes of headache with vomiting for 6 months. Plain CT of the head and MRI of the brain revealed fourth ventricular cysticercal cyst with acute obstructive hydrocephalus. Endoscopic excision of the cyst was done along with endoscopic third ventriculostomy and septostomy with external ventricular drain placement. Although we were able to decompress the cysticercal cyst, unfortunately, the cyst got slipped from the grasper leaving the grasped cyst wall in the tooth of the grasper. Through this case report, we want to highlight that such a complication could also happen during neuroendoscopic cysticercal cyst removal and how we dealt with it. Our patient was discharged neurologically intact and was symptom free on follow-up.

A man in his early 70s with a 4-year history of diffuse large B cell lymphoma (DLBCL) was admitted to our hospital with diplopia and achromatopsia. Neurological examination revealed visual impairment, ocular motility disorder and diplopia on looking to the left. Blood and cerebrospinal fluid investigations showed no significant findings. MRI revealed diffusely thickened dura mater and contrast-enhanced structures in the left apical orbit, consistent with hypertrophic pachymeningitis (HP). We performed an open dural biopsy to distinguish the diagnosis from lymphoma. The pathological diagnosis was idiopathic HP, and DLBCL recurrence was ruled out. Following methylprednisolone pulse and oral prednisolone therapy, his neurological abnormalities gradually receded. Open dural biopsy played an important role not only in diagnosing idiopathic HP but also in relieving the pressure on the optic nerve.

We present a case of a woman in her 60s with acute left hemispheric ischaemic stroke syndrome due to tandem occlusions of the proximal left internal carotid artery and left middle cerebral artery. This was treated with emergent carotid artery stenting and endovascular clot retrieval. The patient made a complete recovery and was discharged home only to represent a few days later with focal neurological symptoms, profound headache and labile blood pressure. The diagnostic and management challenges of reversible cerebral vasoconstriction syndrome, including imaging assessment and the importance of avoiding 'diagnostic anchoring' are discussed.

A woman in her 70s presented with acute bilateral retro-orbital headache, diplopia, chemosis and eye swelling. Ophthalmology and neurology were consulted after detailed physical examination and diagnostic workup including laboratory analysis, imaging and lumbar puncture. The patient was diagnosed with non-specific orbital inflammation and was started on methylprednisolone and dorzolamide-timolol for intraocular hypertension. The patient's condition improved slightly, but a week later, she developed subconjunctival haemorrhage in the right eye, which prompted investigation for a low-flow carotid-cavernous fistula. Digital subtraction angiography showed bilateral indirect carotid-cavernous fistula (Barrow type D). The patient underwent bilateral carotid-cavernous fistula embolisation. Her swelling improved considerably on day 1 after the procedure and her diplopia improved over the following weeks.

We report a case of a woman in her 30s who struggled with a life-long history of trichotillomania (TTM; hair-pulling disorder), which was unsuccessfully treated with behavioural therapy and selective serotonin reuptake inhibitors. In addition to TTM, our patient had a history of chronic migraine which brought her to our clinic, and treatment with onabotulinumtoxinA (OBTA) was initiated per the Phase III REsearch Evaluating Migraine Prophylaxis Therapy protocol. After experiencing improvement with migraine symptoms, she began off-label treatment with OBTA for her TTM with 45 units being injected, 5 units per site, in diffuse regions of her scalp, primarily on the affected areas of TTM-induced alopecia. The patient reported marked improvement in her TTM signs and symptoms, which resulted in hair regrowth as early as the first follow-up visit 12 weeks post-treatment initiation. Treatment effects were maintained, and additional hair regrowth was observed at the 1-year post-treatment visit, which equated to four cycles of treatment.

With an increasing number of patients seeking gender-affirming hormone therapy (GAHT), the clinical impact of testosterone treatments on headache needs to be determined. Our case report looks at the potential effect of testosterone on migraine among transgender patients. We present two transmasculine patients who used masculinising hormone therapy with testosterone. Both patients described their headache as moderate-to-severe pain with features that fulfilled the criteria for chronic migraine without aura. Following GAHT, one patient improved in both frequency and intensity of headache symptoms while the other noted improvement in headache intensity alone. Our report postulates that testosterone therapy may have a positive impact on headaches in individuals participating in GAHT, highlighting the need for further research on the role of testosterone therapy on headache in transmasculine individuals.

The varicella zoster virus (VZV) is a ubiquitous, neurotropic pathogen capable of reactivation from sensory ganglion cells to cause dermatomal herpes zoster infection, alongside a range of pathologies within the central nervous system. The presence of VZV cerebellitis without skin manifestations, however, is exceedingly rare in immunocompetent adults.We report a case of VZV cerebellitis in an immunocompetent woman in her 70s, in the absence of a rash. The patient presented with a 2-week history of progressive gait ataxia, headache and mild confusion. Serological tests and neuroimaging were unremarkable. Diagnosis was confirmed through cerebrospinal fluid (CSF) analysis which revealed lymphocytosis and the presence of VZV DNA on PCR analysis. The patient showed symptomatic improvement following empirical acyclovir treatment, corroborated by favourable CSF analysis 10 days post-treatment initiation.Infective aetiology, including VZV, should be considered in patients presenting with acute cerebellar ataxia, even in immunocompetent adults with an absence of dermatological signs.

Tolosa-Hunt syndrome is a rare cause of painful ophthalmoplegia, most commonly presenting with retro-orbital pain and eye motor nerve palsy, most often affecting a single eye. The condition is characterised by an idiopathic process causing granulomatous inflammation to the cavernous sinus affecting, one or multiple cranial nerves that pass therein. The mechanism underlying the inflammation is not well understood, but patients have been observed to respond to steroids during a flare. We present this as a unique case where a multidisciplinary team diagnosed Tolosa-Hunt syndrome despite non-specific MRI findings in the cavernous sinus 1 day following an initially normal MRI.

After interdisciplinary consent, a male patient in his 50s received endovascular treatment of an innocent supraophthalmic aneurysm of the internal carotid artery with a WEB (woven endo bridge) device and stenting. In the medical history, a migraine with aura was reported. A week after intervention, the patient developed an ipsilateral cluster-like headache responsive to classical interventions. Inflammation of the carotid wall near the stent was demonstrated to be associated with the headaches and was responsive to steroid treatment.The presented case demonstrates that postinterventional headache comprises more headache entities than the often reported migraine and tension-type headache with a considerable impact on the patients' quality of life. The case supports the vascular hypothesis of cluster headache pathophysiology, potentially contradicting current models and assumptions.

Autoimmune glial fibrillar acidic protein (GFAP) astrocytopathy typically presents as acute or subacute meningoencephalitis with or without myelitis. We describe a case of autoimmune GFAP astrocytopathy that mimicked tuberculous meningitis. A man in his 70s was referred to our hospital with lethargy persistent for 2 months, appetite loss for 1 month and fever with headache for 10 days. The cerebrospinal fluid test revealed lymphocytic pleocytosis with elevated adenosine deaminase (ADA). Laboratory investigations ruled out microbial and neoplastic causes. Empirical therapy for tuberculous meningitis combined with corticosteroid improved the patient's condition. Culture for Mycobacterium tuberculosis failed to show microbial growth despite 1 month of incubation. The cerebrospinal fluid was examined for GFAP antibody and returned positive result. Antituberculous agents were discontinued, and corticosteroid was administered until patient's symptoms resolved completely. Thus, clinicians should consider autoimmune GFAP astrocytopathy as one of the differential diagnoses of lymphocytic meningitis with elevated ADA.

Homozygous familial hypercholesterolaemia (HoFH) is a disorder affecting low-density lipoprotein (LDL) receptor genes. Patients typically have a triad of elevated LDL-cholesterol (LDL-C), xanthomatosis and premature atherosclerotic cardiovascular disease. Our patient, a preteen boy, presented with signs of hypertensive encephalopathy. Physical examination showed arcus cornealis, planar xanthomas and tuberous xanthomas. After appropriate investigations, a direct aetiology of the hypertension could not be elucidated; however, our patient's hypertension resolved with the reduction in serum lipid levels. ß-hydroxy ß-methylglutaryl coenzyme A reductase and cholesterol absorption inhibitors were administered as first-line treatment. A significant proportion of patients with HoFH continue to have elevated LDL-C levels, thereby requiring second-line agents, such as proprotein convertase subtilisin/kexin type inhibitors (evolocumab), microsomal triglyceride transfer protein inhibitors (lomitapide) and angiopoietin-like protein inhibitors (evinacumab). This case report aimed to raise awareness among paediatricians to consider HoFH as a possible aetiology in a child presenting with hypertension and suggestive physical findings.
