OBJECTIVE: To evaluate the imaging characteristics and diagnostic utility of the "Dinosaur tail sign" in the diagnosis of cerebrospinal fluid (CSF) leakage. BACKGROUND: The authors propose the "Dinosaur tail sign," defined as a combination of the dorsal epidural hyperintensities, fat tissue, spinal cord, and cauda equine on lumbosacral sagittal fat-suppressed T2-weighted image (FST2WI), as a sensitive indicator for diagnosing CSF leakage. METHODS: Imaging characteristics of the "Dinosaur tail sign" was evaluated in seven spontaneous intracranial hypotension (SIH) and 23 iatrogenic CSF leakage (ICSFL) patients...

OBJECTIVE: To describe two patients with recurring unilateral brief headaches that fulfilled criteria for both primary cough headache (CH) and chronic paroxysmal hemicrania (CPH). BACKGROUND: CH is typically a bilateral headache, specifically triggered by cough, straining, or other Valsalva maneuvers. The report of cases sharing features with other primary headache disorders, such as CPH, suggest common pathogenic mechanisms. METHODS: Case reports...

OBJECTIVE: To provide clinically relevant insights on the identification of the muscles and techniques involved in the safe and effective use of onabotulinumtoxinA for chronic migraine prophylaxis. BACKGROUND: Although guidance on the use of onabotulinumtoxinA for chronic migraine is available, based on the Phase III Research Evaluating Migraine Prophylaxis Therapy (PREEMPT) clinical program, clinical experience has shown that insufficient understanding of the anatomy and function of the head and neck muscles may lead to undesirable outcomes and suboptimal efficacy...

OBJECTIVE: To determine whether baseline nausea or prior triptan treatment for migraine impact the effectiveness of diclofenac potassium for oral solution in treating acute migraine. BACKGROUND: A great deal of variability exists in patients' response to migraine medications. Migraine-associated nausea is common and debilitating and can reduce the effectiveness of oral medications. It may cause patients to delay taking oral medications, which is known to diminish therapeutic outcomes, or to avoid taking them altogether...

Rigmor Højland Jensen
PREMISE: Tension-type headache (TTH) is the most prevalent form of primary headache in the general population but paradoxically the least studied headache. PROBLEM: In this article, the epidemiology and diagnostic challenges of TTH are presented and discussed. The typical features and differential diagnosis of TTH are highlighted and the situations more likely to raise doubts are discussed. POTENTIAL SOLUTION: A structured approach to the patient and a better comprehension of the very frequent coexistence of migraine and medication overuse headache in the clinical population are emphasized...

BACKGROUND: Pain acceptance involves willingness to experience pain and engaging in valued activities while pain is present. Though pain acceptance could limit both headache-related disability and pain interference in individuals with migraine, few studies have addressed this issue. This study evaluated whether higher levels of total pain acceptance and its two subcomponents, pain willingness and activity engagement, were associated with lower levels of headache-related impairment in women who had both migraine and overweight/obesity...

Pourfour du Petit (PDP) syndrome is a rare disorder characterized by ipsilateral mydriasis, eyelid retraction, and hemifacial hyperhidrosis caused by hyperactivity of the ipsilateral oculosympathetic pathway. A case is presented of PDP syndrome associated with likely ipsilateral occipital neuralgia. We review the causes and co-morbidities and the clinical features of PDP.

When MRI scans of the brain are obtained for evaluation of primary headaches in adults, incidental findings are commonly present. After a review of the prevalence of incidental findings and normal anatomical variants, 21 types are presented.

OBJECTIVE: To describe the diagnostic types and characteristics of headaches in soldiers with mild traumatic brain injury during the wars in Afghanistan and Iraq. BACKGROUND: Persistent post-traumatic headache interferes with returns to activity or duty. The most commonly cited headache diagnosis after concussion is migraine. We hypothesize that headache diagnosis type, eg, migraine, is not sufficient to predict relationships with occupational outcomes after concussion...

Steven Lomazow
BACKGROUND: Franklin Delano Roosevelt's fatal brain hemorrhage on April 12, 1945 provides an excellent platform for the study of the potential causes of one of the most famous headaches in history. IMPRESSION: The differential diagnosis of thunderclap headache, including hypertension and melanoma, is discussed, as are Roosevelt's health problems in the context of how serious diseases of our leaders can have a tangible effect upon historical interpretation. DISCUSSION: A large body of evidence is presented in support of a probable cover-up of Roosevelt's health problems, perpetrated by his doctors and close confidantes...

BACKGROUND: Arteriovenous malformations (AVMs) can underlie many diverse neurological signs and symptoms. Headaches are a common presentation that can have a significant impact on quality of life. OBJECTIVE: The authors investigated Gamma Knife(®) stereotactic radiosurgery (SRS) outcomes in patients with AVMs and associated headaches. METHODS: This retrospective study analyzed 102 patients with AVMs who underwent SRS between 1995 and 2013...

PREMISE: Classical trigeminal neuralgia (CTN) and the short-lasting unilateral neuralgiform headache attacks (SUNHA) are clinically similar. PROBLEM: The SUNHAs include short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA). Shared clinical signs with CTN include severe, unilateral trigeminal pain that is often triggered by innocuous stimuli and accompanied by a dull persistent background pain...

OBJECTIVES: To survey experts in Headache Medicine on their opinions regarding appropriate non-inferiority margins for outcomes commonly used in migraine research. METHODS: Members of the American Headache Society and the Canadian Headache Society were invited to participate in the Non-Inferiority Margins in Migraine Research (NIMM) survey. Adult and child neurologists with expertise in Headache Medicine were eligible to participate. The survey had a multiple choice format and comprised questions on respondent characteristics, eligibility, as well as expert opinion on non-inferiority margins for outcomes commonly used in trials of both prophylactic and acute interventions for migraine...

INTRODUCTION: To investigate the correlation of microstructural parameters with CSF pressure and macroscopic changes assessed by diffusion tensor imaging (DTI) in patients with idiopathic intracranial hypertension (IIH). METHODS: Twenty-three patients with IIH as well as age-, sex-, and body mass index (BMI)-matched controls underwent high resolution MR imaging of the optic nerve sheaths (ONS), pituitary gland, and ventricles. For DTI data a voxelwise permutation analysis was performed for the whole brain and ROI analysis was performed for the optic nerve and optic radiation...

#20
Gretchen E Tietjen, Stuart A Collins
BACKGROUND: A growing body of literature suggests that migraineurs, particularly those with aura, have an increased risk for ischemic stroke, but not via enhanced atherosclerosis. The theory that micro-emboli induced ischemia provokes cortical spreading depression (ie, symptomatic aura) in migraineurs but transient ischemic attacks in others highlights a potential role for hypercoagulability as a link between migraine (with aura) and stroke. AIM: Our objective is to summarize the literature evaluating the association of migraine with various acquired or inheritable thrombophilic states, including those related to elevated estrogen levels, endothelial activation and dysfunction, antiphospholipid antibodies (aPL), deficiency of coagulation inhibitors, and presence of certain genetic polymorphisms...
