Recurrence and long-term outcomes of Tolosa-Hunt syndrome.

BACKGROUND AND PURPOSE: Tolosa-Hunt Syndrome (THS) is a rare disorder, and detailed clinical information and treatment outcomes have yet to be fully elucidated. This study aims to investigate the clinical features and factors associated with the treatment outcomes of THS, as defined by the established diagnostic criteria. METHODS: This study retrospectively recruited 91 patients with a diagnosis of THS from 2003 to 2020. We analyzed the clinical features and outcomes, the initial treatment response, recurrences, and the final treatment response. RESULTS: Isolated ocular motor nerve palsy was the most common (82.4%) finding of ophthalmoplegia, involving the oculomotor nerve in more than half of the cases (52.0%). The MRI lesions were mostly observed in the cavernous sinus (94.5%) with an extracavernous extension in about one-third of them. Five patients showed only extracavernous lesions. A total of 25 (27.5%) patients experienced recurrence. Recurrence occurred during steroid tapering as part of the initial treatment in seven, while in 18 patients, it happened after the successful termination of the initial treatment. However, all patients achieved complete remission at the final. Age was associated with a decrease in initial symptom duration (HR = 1.023, CI = 1.004-1.044) as well as an increase in recurrence-free duration (HR = 0.944, CI = 0.911-0.978). High-dose corticosteroid treatment was associated with a decrease in initial symptom duration (HR = 1.642, CI = 1.001-2.695) and total treatment duration (HR = 2.203 CI = 1.302-3.730). CONCLUSIONS: THS can recur frequently especially in younger but have a favorable prognosis. High-dose corticosteroids can be an effective initial treatment and reduce the total treatment duration.

Review of Tolosa-Hunt Syndrome, Recent Updates.

PURPOSE OF REVIEW: We aim to present diagnostic considerations and management insights on Tolosa-Hunt syndrome. We highlight recent controversies in this field and emerging literature. RECENT FINDINGS: The diagnostic categorization of Tolosa-Hunt syndrome remains controversial, with imaging negative cases described in the literature and an increasing literature of secondary causes falsely diagnosed as Tolosa-Hunt syndrome. Response to steroids can fulfill diagnostic criteria, but newer management strategies are available in treatment-resistant patients, such as steroid-sparing agents or radiotherapy. Tolosa-Hunt syndrome has become controversial; the entity of granulomatous inflammation of the cavernous sinus and possible extension into orbital fissure and posterior orbit of late has been re-evaluated. Recent case series and reviews have outlined multiple false positive (neoplasm or infection) and negative (no imaging findings) diagnoses. In the future, when assessing whether a patient has this entity, we caution readers to closely follow patients for secondary causes and consider this entity in differential even if MRI is non-revealing. Additionally, biopsy should be regarded as a gold standard for diagnosis and utilized, especially in uncertain cases. The diagnostic categorization of Tolosa-Hunt syndrome may need reconsideration in future versions of the ICHD.

Tolosa-Hunt syndrome and recurrent painful ophthalmoplegic neuropathy, case reports: what to do and when?

BACKGROUND: Tolosa-Hunt syndrome (THS) and recurrent painful ophthalmoplegic neuropathy (RPON) are rare diseases reported within the "Painful lesions of the cranial nerves" section of the International Classification of Headache Disorders-3rd edition (ICHD-3). In case of a first painful attack, differential diagnosis could be challenging and many pitfalls are due to the rarity of the disorders and the lack of information about correct medical management in youngsters. CASE PRESENTATION: Our main purpose was to report a new case of THS and a new case of RPON describing management and diagnostic investigation at the time of the first episode. In both cases of THS (13 years old) and RPON (14 years old) a unilateral periorbital headache associated with acute onset of ipsilateral third cranial nerve paresis, scarcely responding to non-steroidal anti-inflammatory drugs (NSAID), was present at the beginning of the first attack. Brain MRI with "time-of-flight" (TOF) angiography and the need to administer steroids (after 72 h from onset) in order to stop pain were the most important handles allowing us to adopt the correct management both in THS or RPON since onset and to face recurrences in RPON by avoiding useless therapy during follow-up. CONCLUSION: Unilateral periorbital headache associated with third-fourth or sixth cranial nerve paresis should ideally be investigated with a full work-up, comprehensive of brain MRI with TOF angiography since the first attack. In cases with negative brain MRI spontaneous resolution should be considered and watchful waiting might be advisable before starting steroid therapy.

Frozen overnight: Acute orbital apex syndrome caused by aspergillosis.

PURPOSE: to describe a rare case of orbital apex syndrome caused by aspergillosis with acute presentation. CASE DESCRIPTION: retrospective case report of a 70-year-old man who developed unilateral ophthalmoplegia overnight. He was initially given the diagnosis of suspect Tolosa-Hunt syndrome, but biopsy of the involved tissue showed aspergillosis. CONCLUSION: orbital apex syndrome caused by fungal disease is a life-threatening condition that should be promptly diagnosed and treated. It may present acutely and should not be misdiagnosed as Tolosa-Hunt syndrome. To our knowledge this is the first such case report in the English ophthalmic language Literature.

Complete ophthalmoplegia diagnosed as Tolosa-Hunt syndrome on interval MRI.

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.

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.

Hypopituitarism and cranial nerve involvement mimicking Tolosa-Hunt syndrome as the initially presenting feature of diffuse large B-cell lymphoma: a case report.

BACKGROUND: Early diagnosis of lymphoma involving the central nervous system is sometimes difficult but emergent to avoid the delay of therapeutic initiation. Pituitary insufficiencies are usually associated with lymphoma in the pituitary gland. There have been no cases of lymphoma originating from extra pituitary gland with hypopituitarism that simultaneously presenting unilateral upper cranial nerve palsies and ophthalmalgia. These symptoms are mostly caused by neoplastic involvement of the skull base or benign diseases such as Tolosa-Hunt syndrome (THS). We report a case of lymphoma with unique clinical courses initially presenting hypopituitarism and symptoms mimicking THS with a mass in sphenoidal and cavernous sinuses accompanying sphenoidal bone erosion. CASE PRESENTATION: A 71-year-old woman visited our hospital with left ophthalmalgia, ptosis, and diplopia. Neurological findings revealed left oculomotor, trochlear and abducent nerve palsies. Endocrine tests indicated partial hypopituitarism. Initial CT and MRI revealed that a mass in sphenoidal and cavernous sinuses had invaded the sella with osteolysis of the sphenoid bone. At around four weeks, almost all the symptoms of cranial nerve palsies were relieved. Seven weeks later, she had a high fever and cervical lymph node (CLN) swellings. CLN biopsy revealed CD20-positive B-cells. She was diagnosed with diffuse large B-cell lymphoma (DLBCL). 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) revealed elevated uptake at the erosion lesion of the sphenoidal bone, but not the pituitary gland. After chemotherapy, all the symptoms related to systemic lymphoma were relieved, but partial hypopituitarism remained. The mass in sphenoidal and cavernous sinuses and elevated uptake by PET/CT were dissolved. CONCLUSION: This case of DLBCL had a unique clinical course; initial presentation of hypopituitarism and symptoms mimicking THS. There was also rare demonstration of mass lesions related to DLBCL in the sphenoidal and cavernous sinuses compressing the pituitary gland through an eroded area of the sphenoidal bone. It should be clinically cautioned that DLBCL can be associated with erosion of the sphenoidal bone and cause both hypopituitarism and THS-mimicking symptoms.

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.

Tolosa-Hunt syndrome presenting with features of a trigeminal autonomic cephalalgias and pituitary enlargement.

Tolosa-Hunt syndrome is understood as a steroid-responsive, relapsing-remitting, unilateral headache disorder associated with ipsilateral cranial neuropathies, of a probable granulomatous aetiology. The diagnosis is made clinically from the history and examination, supported by appropriate imaging. Here the authors report a case of Tolosa-Hunt syndrome with a headache phenotype mimicking a trigeminal autonomic cephalalgias (hemicrania continua), and serial MRI studies showing a stable enlarged pituitary. Due to her initial lack of clinical signs, she was diagnosed with chronic migraine, revised to hemicrania continua based on indomethacin response, then revised back to chronic migraine. Her final diagnosis was achieved after she developed a left cavernous sinus syndrome 4 years into her disease course. This case shows that Tolosa-Hunt syndrome may present with a non-side-locked headache and delayed development of clinical signs. Clinicians should also maintain a high degree of suspicion when faced with incidental MRI findings.

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.

Recurrent painful ophthalmoplegic neuropathy: a cause for recurrent third nerve palsy in a child.

Recurrent painful ophthalmoplegic neuropathy (RPON), previously called ophthalmoplegic migraine, is a rare condition characterised by recurrent episodes of headache and ophthalmoplegia. We report a case of 11-year-old girl with recurrent painful ophthalmoplegia due to isolated right oculomotor nerve involvement. MR brain imaging showed enhancing lesion of cisternal segment of right oculomotor nerve. A possibility of Tolosa Hunt syndrome was considered and she was treated with glucocorticoids, followed by azathioprine due to recurrence. In the fourth episode, she developed migraine headache followed by right third nerve palsy, after which the diagnosis was revised to RPON. She was started on flunarizine along with short-term glucocorticoids. At 1-year follow-up, she remained asymptomatic. RPON should be considered in patients with recurrent third nerve palsy to avoid inadvertent long-term exposure to immunosuppressive agents.

From left to right: an unusual presentation of Tolosa-Hunt syndrome with bilateral eye involvement.

Here we discuss a presentation of Tolosa-Hunt syndrome (THS) in a 44-year-old female with new right-eye ptosis, ophthalmoplegia and headache. Four days prior, she had almost identical ptosis and ophthalmoplegia in her left eye, which resolved. Cavernous sinus inflammation and symptom improvement with glucocorticoid treatment indicated THS with bilateral eye involvement, a presentation which may be undervalued by the current THS classification.
