Painful ophthalmoplegia: an unresolved clinical problem

Evaluation of Patients with Painful Ophthalmoplegia for Benign and Secondary Etiologies

This study aims to establish the final definite etiology among patients with long-term follow-up for painful ophthalmoplegia. The data of 44 cases (16 females, 28 females) were examined. In the first diagnosis, subjects were scanned in terms of benign and secondary etiologies. Clinical and radiological follow-up results of patients were recorded. During the follow-up period, data on clinical outcomes (relapse or progression), treatment responses, and final diagnoses were evaluated In total, 49 episodes of painful ophthalmoplegia (44 patients) were evaluated. Secondary etiologies were identified in 21 patients benign/secondary tumours causes in 10, inflammatory in 1, infectious in 3, vascular in 3, demyelinating disease in 1, autoimmune in 2, drug-related cause in 1. 23 patients with benign etiologies; 11 had Tolosa-Hunt syndrome (THS), 2 had Recurrent Painful Ophthalmoplegic Neuropathy (RPON), and 10 had diabetic ophthalmoparesis (DO). 7 of 11 patients with THS met the International Classification Headache Disorders 3rd edition (ICHD-3 beta) criteria, 4 were with a normal MRI, and 1 had a recurrence. 9 of 10 patients with benign/secondary tumours causes were malignant, and 7 died due to disease progression during the treatment process. One of ten patient was followed with diabetic ophthalmoparesis and was diagnosed with cavernous sinus involvement of B-cell lymphoma as a result of clinical progression during follow-up. Painful ophthalmoplegia is a complex clinical condition with a broad differential diagnosis with malignant and benign etiologies. A detailed clinical examination, imaging, and long-term follow-up are essential for accurate diagnosis and treatment management.

Recurrent Painful Ophthalmoplegic Neuropathy: A case report with atypical features and a review of the literature

INTRODUCTION

Recurrent Painful Ophthalmoplegic Neuropathy, previously known as Ophthalmoplegic Migraine, is a poorly characterized disorder mainly because there are few cases described. We report a new case of Recurrent Painful Ophthalmoplegic Neuropathy and a review of the literature to contribute to increasing the knowledge of the clinical features of this disorder.

CASE REPORT AND REVIEW OF LITERATURE

A 45-year-old woman presented with adult-onset recurrent attacks of abducens and oculomotor palsy associated with diplopia followed by headache. Most notably, pain always presented many days after oculomotor impairment, a feature never described in the literature. A diagnosis of possible Recurrent Painful Ophthalmoplegic Neuropathy was made after excluding other possible mimicking disorders. Symptoms usually resolved gradually with corticosteroid therapy, albeit without a clear-cut benefit.Clinical data collected from 1989 to 2022 showed that adult onset in Recurrent Painful Ophthalmoplegic Neuropathy is not uncommon. While III cranial nerve palsy is typical, VI and IV nerve palsy have also been described.

PATHOPHYSIOLOGY AND DIAGNOSIS

Several hypotheses have been proposed, including nerve compression, ischemia or inflammation/demyelination, but none has been completely accepted.Diagnosis remains of exclusion; magnetic resonance imaging and blood exams are key in differential diagnosis.

CONCLUSIONS

Our case gives us the possibility to expand the clinical features of Recurrent Painful Ophthalmoplegic Neuropathy, also contributing to updating the pathophysiological hypotheses.

A Clinical Retrospective Study of Recurrent Painful Ophthalmoplegic Neuropathy in Adults

Introduction

Recurrent painful ophthalmoplegic neuropathy (RPON) is quite rare and usually occurs in children. In this report, we describe the clinical features, diagnosis, and treatment of RPON in adults.

Methods

A retrospective review was conducted of all RPON cases seen and treated at the Zhongshan Ophthalmic Center of Sun Yat-sen University and the Department of Neurology of the First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China, over the period from January 2016 to May 2020.

Results

A total of 8 patients (3 males and 5 females) with a mean age of 42.9 years (range: 23–64 years) met the diagnostic criteria of RPON. Headaches were present prior to the onset of ophthalmoplegic neuropathy in 50% of these patients, while in the remaining 50%, headaches occurred simultaneously with eye symptoms. The degree of these headaches was described as being mild or moderate. Abnormalities involving cranial nerve III were the most frequently reported pathologies (6 cases, 75%), followed by nerve VI (4 cases, 50%) and then nerve IV (1 case, 12.5%) (more than one nerve was affected in some cases). Following either with glucocorticoid treatment or with observation only, symptoms and signs within all 8 patients completely dissipated within 3–28 days.

Conclusions

All adult cases of RPON along with their clinical features as reported here were similar to those of children.

How and when to refer patients diagnosed with secondary headache and other craniofacial pain in the Emergency Department and Primary Care: Recommendations of the Spanish Society of Neurology's Headache Study Group

INTRODUCTION

When secondary headache is suspected and the patient is referred to the emergency department or to the outpatient neurology clinic, it is important to know which are the appropriate complementary examinations to perform and the suitable referral pathway for patients to follow. In order to establish recommendations on this matter, the Spanish Society of Neurology's Headache Study Group (GECSEN) has decided to issue a series of agreed recommendations constituting a referral protocol for patients with headache and/or craniofacial neuralgias.

DEVELOPMENT

Young neurologists with an interest and experience in headache were invited to draft a series of practical guidelines in collaboration with GECSEN's Executive Committee. For practical reasons, the document was divided into 2 articles: the first focuses on primary headaches and craniofacial neuralgias and this second article on secondary headaches and other craniofacial pain. In order for the recommendations to be helpful for daily practice, they follow a practical approach, with tables summarising referral criteria, examinations to be performed, and referral to other specialists.

CONCLUSIONS

We hope to offer a guide and tools to improve decision-making regarding patients with headache, identifying complementary tests to prioritise and referral pathways to be followed, in order to avoid duplicated consultations and delayed diagnosis and treatment.

Evaluation and Management of Tolosa-Hunt Syndrome in Children: A Clinical Update

BACKGROUND

Tolosa-Hunt syndrome is a painful ophthalmoplegia caused by an inflammatory process of unknown etiology in the region of the cavernous sinus, orbital apex, or superior orbital fissure. This disease is rare in the pediatric population. The objective of this study was to provide a clinical framework for the evaluation and treatment of children with this disorder. A systematic approach to the diagnosis of painful ophthalmoplegia in children is proposed.

METHODS

We present a 15-year-old girl whose clinical presentation and neuroradiological findings support a diagnosis of Tolosa-Hunt syndrome as defined by the 2013 International Classification of Headache Disorders (Third Edition, ICHD-3 beta) diagnostic criteria. An exhaustive systematic literature search based on these criteria yielded 15 additional cases of Tolosa-Hunt syndrome in children. Clinical, demographic, and radiological features were retrospectively analyzed. The results and statistical analyses are reported.

RESULTS

A total of 16 individuals were included in the final analysis. This review summarizes the current knowledge and recommendations for the diagnosis and management of pediatric Tolosa-Hunt syndrome. It highlights demographic, clinical, and radiological features of this disease in children and underscores areas of the literature where evidence is still lacking.

CONCLUSIONS

Overall, Tolosa-Hunt syndrome seems to follow a similar course in children compared to adults. The diagnostic approach and treatment require specific considerations. New observations and possible features of pediatric Tolosa-Hunt syndrome are discussed. Further research is needed to optimize clinical detection and medical management of this disease.

Cavernous sinus syndrome: need for early diagnosis

Cavernous sinus syndrome (CSS) is a rare condition characterised by ophthalmoplegia, proptosis, ocular and conjunctival congestion, trigeminal sensory loss and Horner's syndrome. These signs and symptoms result from the involvement of the cranial nerves passing through the cavernous sinus. We report the case of a 53-year-old man with a history of daily stabbing headache associated with dizziness, progressive blurred vision, right ocular pain, ptosis and ophthalmoplegia. After working up the patient, a meningioma was identified as the cause of the CSS. Despite advances in neuroimaging techniques, in some cases, the aetiology of CSS remains difficult to determine. We highlight the clinical and radiological features of a meningioma, one of the causes of CSS. Early diagnosis and treatment of CSS play a key role in a better prognosis.

Factors that influence Tolosa-Hunt syndrome and the short-term response to steroid pulse treatment

Some but not all patients with Tolosa-Hunt syndrome (THS) have dramatic responses to steroid treatment. A systematic study about the factors that may influence the steroid response of THS patients has not been published. We retrospectively identified 40 patients diagnosed with THS and treated with steroids with respect to patient age at onset, gender, the cranial nerve(s) involved, as well as imaging findings and laboratory tests. Within the context of these data we evaluated the therapeutic efficacy of steroid treatment and recurrence of attacks. We did not note a significant relationship between genders, whether THS was benign or inflammatory, the distribution of cranial nerve palsies, the initial dose of steroids and the effectiveness of steroid treatment for relief of orbital pain or cranial nerve palsies at 72 h or 1 week after treatment. Our study reveals that a rapid alleviation of pain by steroid treatment is a characteristic feature of THS patients. The alleviation of cranial nerve palsy is somewhat slower and more variable, and may involve additional mechanisms. There is an effect of patient age and whether attacks will recur (recurrence was more likely in patients who were young at the time of first attack), whether THS will be benign or inflammatory (more likely to be inflammatory in young patients) and the short-term response of cranial nerve palsy to steroid treatment, which was more effective in young patients. These relationships may be of value in counseling patients presenting with THS.

Validation of ICHD-3 beta diagnostic criteria for 13.7 Tolosa-Hunt syndrome: Analysis of 77 cases of painful ophthalmoplegia

BACKGROUND

Three editions of International Classification of Headache Disorders (ICHD) diagnostic criteria for Tolosa-Hunt syndrome (THS) have been published in 1988, 2004 and 2013, in ICHD-3 beta, there have been considerable changes [corrected]. The validity of these new diagnostic criteria remains to be established.

METHODS

We retrospectively identified 77 patients with non-traumatic painful ophthalmoplegia (PO) admitted between 2003 and 2013. We reviewed patients' age at onset and gender, time courses between onset of pain and development of cranial nerve palsy, the cranial nerves involved, imaging findings, therapeutic efficacy of steroid treatment and recurrence of attacks.

RESULTS

THS was the most frequent type of PO (46/77). In THS patients, the third cranial nerve was most commonly involved (76.3%). The median time interval between pain and cranial nerve palsy was two days, although in five patients (10.9%) the interval ranged from 16 to 30 days. Definitely abnormal MRI findings were found in 24 patients (52.2%).

CONCLUSIONS

It is essential to rule out other causes of PO in diagnosing THS, with MRI playing a crucial role in differential diagnosis. It may be helpful to understand and master the entity of THS for researchers and clinicians to adjust the gradation and ranking of the diagnostic criteria.

Painful ophthalmoplegia of the right eye in a 20-year-old man

BACKGROUND

Painful ophthalmoplegia is an infrequent but very important presentation in the acute care setting and requires a thorough neurologic evaluation to determine its cause. This clinical sign has a large differential and generally indicates a serious cerebrovascular process.

CASE REPORT

We describe a patient with a subacute presentation of painful ophthalmoplegia, ultimately diagnosed as Tolosa-Hunt syndrome, a rare inflammatory process of the cavernous sinus.

CONCLUSION

This case highlights the importance for the Emergency Physician to quickly recognize painful ophthalmoplegia and rapidly elucidate the cause to prevent further complications for the patient.

A case of orbital Rosai-Dorfman disease responding to radiotherapy

Rosai-Dorfman disease (RDD) is a rare histiocytic disorder most often characterized by painless cervical lymphadenopathy, but it may also present with orbital disease. The clinical course of RDD is variable; it can be either relapsing-remitting or progressive, and the outcome relates to clinical location and treatment response. Orbital RDD can have an insidious onset and similar presentation to other ophthalmic conditions; this can result in a delayed diagnosis. Nearly all cases of orbital RDD cause visual disturbances and require treatment. Because orbital RDD is an uncommon presentation, a variety of interventions have been employed, including surgery, immunotherapy, chemotherapy, and radiotherapy. We present a case of salvage radiotherapy for progressive orbital RDD refractory to surgery and chemotherapy in a pediatric patient.

Les ophtalmoplégies douloureuses de l'enfant: place du syndrome de Tolosa-Hunt et de la migraine ophtalmoplégique

In children with painful ophthalmoplegia, the diagnosis of Tolosa-Hunt syndrome or of ophthalmoplegic migraine should only be considered when tumoral, infectious, inflammatory or vascular causes have been excluded by appropriate investigations. Both entities are classified as "neuralgia" by the International Headache Society, and seem to share a similar pathogenic mechanism. Both diseases have many clinical similarities with slight differences concerning pain characteristics or ocular associated symptoms. High resolution CT scan or contrast enhanced MRI can be necessary to exclude other causes of painful ophthalmoplegia. They can sometimes objectify an inflammatory process of the cavernous sinus in Tolosa-Hunt syndrome or a reversible enhancement and thickening of the cisternal segment of the oculomotor nerve during an ophthalmoplegic migraine. Pain and ophthalmoplegia quickly resolve with corticosteroids. Such treatment may decrease the risk of recurrence. It is important to follow-up these patients for a 2 years period and to repeat the etiologic assessment. We report here 2 cases of children with painful ophtalmoplegia.
