Orbital inflammation following COVID-19 vaccination: A case series and literature review.

PURPOSE: The purpose of the study was to report three cases of orbital inflammation following administration of the COVID-19 vaccination, manifesting as Tolosa-Hunt syndrome (THS) and orbital myositis. METHOD: A retrospective case series and literature review of patients who developed orbital inflammation following a COVID-19 vaccination. RESULTS: One patient presented with Tolosa-Hunt syndrome (THS) 14 days following her third (booster) COVID-19 vaccination, one patient developed orbital myositis 10 days following his first COVID-19 vaccination and one patient developed recurrent orbital myositis 1 and 7 days following her second and fourth COVID-19 vaccination. All patients received the Comirnaty vaccine (Pfizer-BioNTech). A thorough systemic autoimmune disease workup in both patients was unremarkable. Two patients had a prior history of orbital inflammation, with previous involvement of other different orbital structures. Characteristic MRI features for each pathology were observed, supporting the clinical presentation of THS and orbital myositis. There was complete resolution of THS following corticosteroids, with no recurrence at 2 months. Meanwhile, one case of orbital myositis self-resolved at 2 months without use of systemic corticosteroids, while the other patient with orbital myositis required treatment with intra-orbital steroid injections and oral corticosteroids. CONCLUSION: Orbital inflammation has been recognised as a rare adverse effect following COVID-19 vaccination. We present a case series of THS and orbital myositis as varied presentations of this entity.

A 57-year-old man with painful ophthalmoplegia and cavernous sinus involvement: Why this is not Tolosa-Hunt syndrome.

Tolosa-Hunt syndrome (THS) is an idiopathic condition included in the differential diagnosis of painful ophthalmoplegia. Although this was once a common diagnosis, the increasing availability of tests reveals an alternative etiology in many cases. Exclusion of treatable disorders is important, because the prognosis may otherwise be poor. We here describe a patient who presented with painful ophthalmoplegia with an infiltrating lesion in the cavernous sinus. Initially suspected of THS, he had a fatal evolution, and postmortem evaluation revealed cervicocephalic actinomycosis. Actinomycosis diagnosis is often missed, and still represents a challenge to the clinician. We highlight pearls and pitfalls to establish a proper diagnosis to avoid missing a treatable condition in patients with suspected THS.

Clinical and Cerebrospinal Fluid Characteristics in 55 Cases of Tolosa-Hunt Syndrome: A Retrospective Analytical Study.

BACKGROUND: Several case series of patients with Tolosa-Hunt syndrome have been described in the literature; however, few studies have focused on the cerebrospinal fluid (CSF) characteristics. This study aimed to analyse the CSF characteristics of patients with Tolosa-Hunt syndrome. METHODS: Fifty-five patients who fulfilled the 3rd Edition of the International Classification of Headache Disorders diagnostic criteria for Tolosa-Hunt syndrome were included in this study. We retrospectively analysed data on CSF parameters, imaging findings, and clinical characteristics of these patients. RESULTS: Oligoclonal bands (OBs) were detected in the CSF of 13 (13/44, 29.5%) patients. The sex ratio was balanced. The mean age at onset of Tolosa-Hunt syndrome was 46.9 ± 10.23 (range 22-72) years. Eight (8/13, 61.5%) patients had multiple cranial nerve palsies. Lesions limited to the cavernous sinus were found on magnetic resonance imaging in 7 (7/13, 53.8%) patients. OBs were significantly detected more frequently in patients whose samples were evaluated less than 30 days after the onset of this diseases (p = 0.026); however, there were no significant differences in the protein level (p = 0.360) and IgG synthesis rate (p = 0.614). CONCLUSIONS: The detection of OBs in the CSF of patients with Tolosa-Hunt syndrome was not rare. It would be interesting to follow-up patients with OBs to determine whether they eventually developed an otherwise more specific inflammatory diagnosis.

Multiple Cranial Neuropathies and Pachymeningitis in a Patient With a Pathogenic Nucleotide-Binding Oligomerization Domain 2 Polymorphism.

ABSTRACT: An 11-year-old boy presented with 2 weeks of intermittent headache, right orbital pain, and constant diplopia. Brain MRI showed dural thickening and enhancement of the right lateral cavernous sinus, right orbital apex, and tentorium. Initial cerebral spinal fluid analysis showed only mild pleocytosis, and serum diagnostics were unrevealing. The working diagnosis was Tolosa-Hunt syndrome. His pain and sixth nerve palsy resolved with corticosteroids. Five months after initial presentation, he developed new numbness of the right cheek, complete right ophthalmoplegia, and weakness and numbness of his right hand and leg, all of which were responsive to steroids. Fifteen months later, he returned to the emergency department with 2 weeks of left-sided headaches and acute diplopia. On examination, he had a left cranial nerve 6 palsy. Dural biopsy showed diffuse mononuclear inflammatory cell reaction consisting mostly of lymphocytes with no signs of granuloma formation, nor any epithelioid or giant cells. His clinical course was consistent with an autoinflammatory condition of unknown etiology. Genetic testing with an immunodeficiency panel showed a risk allele in NOD2 (nucleotide-binding oligomerization domain 2) c.3019dup (p.Leu1007Prof*2) that is associated with an increased risk for Crohn disease. His clinical condition had similarities to central nervous system sarcoidosis. Because of the similarities between our patient's clinical, imaging, and genetic findings and neurosarcoidosis, he was switched to a more targeted therapy-infliximab. His condition has since been stable for nearly 2 years. In conclusion, genetic testing should be considered in patients with suspected occult autoimmunity.

Tolosa-Hunt Syndrome in Childhood and Adolescence: A Literature Review in the Last 10 Years.

OBJECTIVES: The aim of the study is to review the articles published in the last 10 years on Tolosa-Hunt syndrome (THS) in childhood and adolescence to learn about its clinical and epidemiological characteristics and its therapeutic management. METHODS: Based on the literature search in the major medical databases and using the descriptors "Tolosa-Hunt syndrome and children" and "Tolosa-Hunt syndrome and adolescent" we included articles published between 2009 and 2019. We found 51 articles, but only 11 met the inclusion criteria. RESULTS: There were eight women and four men with THS, whose average age was 12.0 ± 4.3 years, ranging from 4 to 17 years. Magnetic resonance imaging showed inflammation in the cavernous sinus (100%), orbit (25%), and superior orbital fissure (8.3%), unilateral in all patients. The internal carotid artery (58.3%), third (66.7%), sixth (33.3%), and fourth (25%) cranial nerves were injured. Headache was located in the orbital region, ipsilaterally to nerve involvement and had mild to severe intensity. Corticosteroid was the treatment used in 91.7% of the patients. They were followed for an average of 13.4 ± 12.4 months. Only two patients had recurrence of the disease. CONCLUSION: THS is infrequent in childhood and adolescence and knowledge of its clinical and epidemiological characteristics and its therapeutic management is necessary for pediatricians.

Tolosa-Hunt Syndrome: Appraising the ICHD-3 beta diagnostic criteria.

Introduction The term Tolosa-Hunt Syndrome was first used more than half a century ago to describe painful ophthalmoplegia accompanied by cranial nerve palsies. In the decades since, its diagnostic criteria have evolved considerably. The beta version of the 3rd Edition of the International Classification of Headache Disorders narrows these criteria to require the demonstration of granulomatous inflammation on MRI or biopsy. We believe this may introduce challenges to accurate diagnosis. Discussion Requiring the demonstration of granulomatous inflammation for a diagnosis of Tolosa-Hunt Syndrome may introduce the potential for false negative and false positive diagnoses. Although the disorder presents secondary to granulomatous inflammation, MRI technology may not be able to identify it reliably, and biopsy is not always indicated for its symptomatology. Additionally, several cases have been reported of Tolosa-Hunt Syndrome diagnosed with MRI-confirmed granulomatous inflammation that later prove to be attributable to other pathologies. The emphasis on neuroimaging may therefore exclude some true Tolosa-Hunt Syndrome cases and include others resulting from other latent pathologies that are not visible on MRI. Conclusion We wish to offer several potential modifications to the International Classification of Headache Disorders guidelines for Tolosa-Hunt Syndrome, including making the demonstration of granulomatous inflammation on MRI or biopsy non-mandatory and lengthening patient follow-up to two years for cases in which MRI is unrevealing.

Tolosa-Hunt Syndrome - Case Report.

This case report presents a patient diagnosed with Tolosa-Hunt syndrome (THS) after an extensive neuro-diagnostic and neuroimaging evaluation. Diagnostic work-up included thorough physical and neurological examination, complete laboratory serum assessments, neuroendocrine and immunohistochemistry analysis, cerebrospinal fluid analysis, neurophysiology assessment, ophthalmologist examination and neuroimaging. Th e most important diagnostic tool in deriving the diagnosis of THS was neuroimaging evaluation that included baseline and follow-up cranial contrast enhanced magnetic resonance imaging (MRI). Baseline cranial contrast enhanced MRI detected a nonspecific inflammatory granulomatous lesion in the right cavernous sinus extending basally towards the right trigeminal cave (Meckel's cave) and anteriorly towards the apex of the right orbit. Systemic intravenous high-dose corticosteroid therapy was administered for 3 consecutive days and then tapered down to lower oral steroid doses. Following therapy, the patient experienced complete regression of symptoms. Follow-up cranial contrast enhanced MRI showed significant regression of inflammatory lesion in the area of right cavernous sinus, thus verifying the efficacy of the treatment applied. This paper shows that an extensive diagnostic schedule for THS must be conducted prior to therapeutic treatment, for the possibility of alternative diagnosis. Patients suspected of having THS require careful evaluation, appropriate treatment, and follow-up.

Tolosa-Hunt syndrome: an arcane pathology of cavernous venous sinus.

Tolosa-Hunt syndrome, an idiopathic granulomatous inflammation of the cavernous sinus, is primarily a diagnosis of exclusion. The majority of patients present with unilateral orbital pain and features suggestive of paralysis of one or more of the cranial nerves passing through the cavernous sinus and/or superior orbital fissure. MRI of the head may show unilateral enhancement of the cavernous sinus and orbital apex. Treatment is with high-dose intravenous steroids followed by tapering oral steroids. Rapid amelioration of pain within 24-48 h supports this rare diagnosis. Resolution of neuropathies may take longer. We describe a case of a young man who presented with left periorbital pain, complete ophthalmoplaegia and ptosis of the left eye. MRI showed enhancement of the left cavernous sinus and orbital apex. High dose steroids led to complete resolution of pain, while ptosis and ophthalmoplaegia improved gradually.

The evaluation of ICHD-3 beta diagnostic criteria for Tolosa-Hunt syndrome: a study of 22 cases of Tolosa-Hunt syndrome.

The objective of the study was to evaluate the amended International Classification of Headache Disorders (third edition, beta version, ICHD-3 beta) with a retrospective analysis. A total of 22 patients diagnosed with painful ophthalmoplegia and Tolosa-Hunt syndrome (THS) in our hospital were retrospectively studied. The following clinical data were collected: symptoms, signs, location of inflammatory tissue, time interval of paresis following the onset of pain, pain and signs of resolution, follow-up and relapse. Pain and diplopia were found in 22 (100 %) and 20 cases (91 %). The sympathetic nerve was involved in 6 cases (27 %). Paresis followed the pain for an average of 8 ± 5.87 days. Serial magnetic resonance imaging (MRI) revealed granulomatous lesion that was visible in 20 patients (91 %). 19 patients (86 %) demonstrated the lesions located in the cavernous sinus, orbital apex or superior orbital fissure. One lesion extended to the intracranial structure. Pain was relieved in 20 cases (91 %) within 72 h and no patient had complete relief from paresis. According to our study, we think the time course of relief should be undefined. Headache location is hard to describe accurately. Normal MRI should be involved in THS diagnoses. The lesion of THS can extend beyond the cavernous sinus and the orbit. The time interval between headache and paresis can exceed 2 weeks.

Probable Tolosa-Hunt syndrome with a normal MRI.

BACKGROUND: We are reporting a rare case of a 60-year-old woman with a past history of end-stage renal disease and non-Hodgkin lymphoma who presented to our hospital with confusion, unilateral headache, painful ophthalmoplegia and ptosis. The patient was diagnosed clinically with Tolosa-Hunt syndrome (THS). RESULTS: THS is a diagnosis of exclusion. Other diseases were ruled out. Magnetic resonance imaging (MRI) of the brain and orbit was negative twice within a week. The patient was treated with corticosteroids with marked improvement of the orbital pain and headache and mild improvement of the cranial nerves palsy. CONCLUSION: Clinical diagnosis of THS could be supported by radiological findings. According to the International Classification of Headache Disorders (ICHD)-3 beta diagnostic criteria, the diagnosis must be confirmed with an abnormal MRI and/or pathological sample. We add to the previous findings of THS with a normal MRI. Although MRI plays a crucial role in differential diagnosis, it should not, nor should the biopsy, be a must for the diagnosis. Limitations of using MRI in some patients are another problem.

[A case of atypical Tolosa-Hunt syndrome with a contrast enhanced lesion of the oculomotor and trigeminal nerves on MRI].

A 30-year-old woman was admitted to our hospital because of intractable orbital pain and ptosis on the left side. On admission, she had left oculomotor, ophthalmic and maxillary nerves palsy. MRI revealed a contrast enhanced lesion of the left oculomotor and trigeminal nerves through the covernous sinus and orbita. We diagnosed her condition as Tolosa-Hunt syndrome. The orbital pain was resolved within 48-hours by the pulse therapy with intra-venous methylpredonisolone. The cranial nerve palsy was gradually improved, but never reached complete remission. The left oculomotor and trigeminal nerves also remained enhanced on MRI until 200 days from the onset. Although there have been few reports to demonstrate the contrast enhancement of cranial nerves in Tolosa-Hunt syndrome, these MRI findings may be a specific indicator of the pathological process.

[Hypertrophic basal pachymeningitis presenting as Tolosa-Hunt syndrome].

We examined 6 patients with hypertrophic basal pachymeningitis using clinical, laboratory and instrumental methods. The clinical presentations were similar to Tolosa-Hunt syndrome although the differences were noted. One case is described in-depth. Based on literature and own observations, we considered the etiology, pathogenesis, diagnostic features and treatment of hypertrophic basal pachymeningitis.

[The coexistence of Tolosa-Hunt syndrome and diabetic cranial mononeuropathy: a case report and a review of literature]. / Tolosa-Hunt sendromu ve diyabetik kraniyal mononöropati birlikteligi: Olgu sunumu ve gözden geçirme.

Tolosa-Hunt syndrome (THS) is described as painful ophtalmoplegia caused by nonspesific inflammation of cavernous sinus or superior orbital fissure, which is response to steroid theraphy. Cranial neuropathies in diabetic patients are extremely rare and occur in older patients with poorly controlled diabetes. A 56-year-old diabetic female patient who developed simultaneous right VI., left III., IV., VI., VII. and maxiller branch of trigeminal nerve palsies with acute periorbital pain applied to our outpatient clinic. Although the coexistence of THS and diabetic cranial neuropathy is an uncommon condition, this should be considered as a possible diagnosis on patients who are admitted with painful ophtalmoplegia and simultaneous multipl cranial neuropathies. We approved to present our diabetic patient with cranial magnetic imaging because of this interesting unity and fasial nerve palsy accompanying to THS.

Tolosa-hunt syndrome associated with cytomegalovirus infection.

We herein present the case of a 38-year-old woman with left-sided oculomotor paralysis with ocular pain that developed after a respiratory infection. Her serum was positive for IgM against GM2 and GalNAc-GD1a gangliosides and cytomegalovirus. Thin-slice magnetic resonance imaging revealed enhanced abnormal tissue located primarily in the superolateral part of the left-sided cavernous sinus, which corticosteroids subsequently obscured with immediate resolution of the patient's ocular symptoms. These clinical features were consistent with those of Tolosa-Hunt syndrome (THS). Our findings in the present patient suggest that cytomegalovirus may provoke granuloma formation in the cavernous sinus, as reported in other various organs, thereby leading to the development of THS.

A comparison of benign and inflammatory manifestations of Tolosa-Hunt syndrome.

BACKGROUND: Tolosa-Hunt syndrome (THS) manifests as a benign or an inflammatory type disease. The nosography differences between these types remain to be elucidated. We aimed to analyze and compare the clinical presentations of benign and inflammatory THS. METHODS: The ward patients who presented with THS from January 1990 to May 2011 were retrospectively reviewed. THS was diagnosed according to the recommendations of the International Headache Society. RESULTS: Of the 53 THS cases (49 patients), 30 (56.6%) were classified as benign and 23 (43.4%) as inflammatory THS. There were strong similarities between the groups in terms of clinical manifestations, laboratory findings, responses to glucocorticoid treatment, and outcomes. However, patients with inflammatory THS tended to be younger (mean age, 43.4 years; P 0.05) and have optic nerve dysfunction (56.5%; P 0.05) and longer disease duration (2.3 ± 1.0 months; P 0.05) compared to those with benign THS (mean age, 56.4 years; mean disease duration, 1.6 ± 0.7 months). The patients with additional involvement of both the optic nerve and the second division of the trigeminal nerve experienced a longer disease duration ( P 0.05). Additionally, patients with orbital pseudotumors had diplopia that responded poorly to treatment with glucocorticoids ( P 0.05). High-dose (>0.5 mg/kg/day) and low-dose (≤0.5 mg/kg/day) prednisolone were equally effective in relieving symptoms in both groups ( P > 0.05). CONCLUSION: Benign and inflammatory THS were highly similar in terms of nosography. The responses to glucocorticoid treatment were generally good except in patients with orbital pseudotumors.

Microsurgical findings of Tolosa-Hunt syndrome.

BACKGROUND: Tolosa-Hunt syndrome (THS), a nonspecific chronic inflammation of the cavernous sinus, is a rarely needed surgical manipulation, even for diagnosis, because corticosteroid therapy is markedly effective against this condition. METHODS: A 59-year-old man presented with left trigeminal neuralgia and right abducens nerve palsy 2 months after the improvement of right oculomotor nerve palsy by corticosteroid therapy. Radiological examinations showed a mass lesion in the left cavernous sinus. The clinical course indicated THS; however, hematological examination showed a positive tuberculous test. We performed a biopsy to rule out tuberculoma in the cavernous sinus. RESULTS: The biopsy was via a left frontotemporal interdural approach. The dura propria over the cavernous sinus was thickened and tightly adhered to the inner layer. The cavernous sinus was occupied by whitish elastic-hard tissue, and it was partially resected through the anterolateral triangle. Histopathological examination showed thick fibrous tissue with numerous degenerated cells and partial inflammatory cell infiltrations without any findings of tuberculoma. The final diagnosis was THS, and corticosteroid therapy was effective despite the chronic fibrous change of the cavernous sinus lesion. CONCLUSIONS: This article presents details of surgical findings of THS that have not been demonstrated in any previous reports.

Painful ophthalmoplegia with simultaneous orbital myositis, optic and oculomotor nerve inflammation and trigeminal nucleus involvement in a patient with herpes zoster ophthalmicus.

Viral infection is a rare cause of painful ophthalmoplegia. We report on a 67-year-old patient who developed painful double vision after a vesicular skin rash on the left forehead. MRI disclosed simultaneous inflammatory lesions in all extraocular muscles, the second and third cranial nerve, as well as pathological signal intensity along the spinal trigeminal tract and nucleus within the medulla oblongata and the pons. Cerebrospinal fluid and serum tests for varicella zoster were positive. The patient was treated effectively with intravenous acyclovir and methylprednisolone. Simultaneous lesions in various neighbouring neural structures may be characteristic for the highly neurotropic behaviour of the herpesviridae and should be considered as a cause of painful ophthalmoplegia that can be depicted by appropriate imaging.

Serial neuroimaging in tolosa-hunt syndrome with acute bilateral complete ophthalmoplegia.

Tolosa-Hunt syndrome (THS) is a very rare, relapsing, and remitting painful ophthalmoplegia caused by nonspecific granulomatous inflammation in the cavernous sinus. To our knowledge, bilateral complete, simultaneous palsies of all 3 cranial nerves associated with extraocular movement have not been reported. We describe the first such patient with bilateral THS that responded quickly to corticosteroid therapy. A 54-year-old man presented with a periorbital and frontal headache with acute bilateral severe blepharoptosis and fixed eyes, which dramatically responded to corticosteroid therapy. He had diabetes mellitus type II. Brain MRI showed granulomatous inflammation in both cavernous sinuses and thickening of the surrounding dura mater of the cranial base, suggesting the coexistence of focal hypertrophic cranial pachymeningitis. Our experience indicates that steroid therapy with strict control of blood sugar should be considered in patients with THS complicated by diabetes. MRI is a valuable tool for serially monitoring the response of lesions to treatment in THS.
