A Case of Recurrent Painful Ophthalmoplegic Neuropathy

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.

Recurrent Painful Ophthalmoplegic Neuropathy Mistaken for Oculomotor Schwannoma: A Case Report

Recurrent painful ophthalmoplegic neuropathy (RPON) is a headache disorder classified as a cranial neuropathy. It is characterized by episodes of unilateral headache followed by ipsilateral ophthalmoplegia due to ocular cranial nerve palsy. Symptoms usually subside spontaneously within weeks to months. RPON commonly occurs in childhood, though it is overlooked at times as a possible differential diagnosis. The pathophysiology of RPON is not entirely clear. Typical magnetic resonance imaging (MRI) findings in children include nerve thickening and gadolinium enhancement. However, these findings are not specific to this condition. Nerve thickening in RPON can resemble schwannomas, thereby causing a diagnostic dilemma. Here, we present a 13-year-old boy with a history of unilateral headaches associated with ipsilateral ptosis and diplopia. The first MRI indicated thickening and gadolinium enhancement of the right oculomotor nerve, which was interpreted as a schwannoma. However, his symptoms resolved after a few weeks and the follow-up MRI showed resolution of nerve changes. This clinical presentation was consistent with RPON. This case demonstrates the need for a careful follow-up of RPON patients.

Case report recurrent painful ophthalmoplegic neuropathy

Recurrent Painful Ophthalmoplegic Neuropathy (RPON) is a rare condition, previously known as Ophthalmoplegic Migraine, it is characterized by headache ipsilateral to paresis of the III, IV or VI cranial nerve, usually affects children or young adults. This is a report of a case of RPON in a 16-year-old woman treated at the Hospital do Servidor Público Estadual de São Paulo.

Recurrent Painful Ophthalmoplegic Neuropathy in an Adult Patient: A Case Report With Literature Review

Recurrent painful ophthalmoplegic neuropathy (RPON), previously known as ophthalmoplegic migraine, is a rare disease that predominantly affects children. Recurrent episodes of ocular cranial nerve paresis with ipsilateral headache characterize this disorder. Diagnosis is mainly clinical with imaging being used as an adjunct. The pathophysiology of the disease is unknown. We present here a case of RPON in a 50-year-old female presenting with multiple episodes of headache and diplopia with associated transient thickening and enhancement of the ipsilateral oculomotor nerve on magnetic resonance imaging (MRI).
