A few of the MS patients have normal brainstem MRI, although they have cranial neuropathy findings in the neurologic examination

📌 3 Key Takeaways

🎯
Objective & Hypothesis:OBJECTIVE: It has been reported that cranial neuropathy findings could be seen in the neurologic examination of multiple sclerosis (MS) patients, although brain magnetic resonance imaging (MRI) may not reveal any lesion responsible for the cranial nerve involvement.
📊
Key Findings & Data:The aim of this study was to determine the frequency of brainstem and cranial nerve involvement, except for olfactory and optic nerves, during MS attacks, and to investigate the rate of an available explanation for the cranial neuropathy findings by lesion localization on brain MRI.

Abstract

OBJECTIVE: It has been reported that cranial neuropathy findings could be seen in the neurologic examination of multiple sclerosis (MS) patients, although brain magnetic resonance imaging (MRI) may not reveal any lesion responsible for the cranial nerve involvement. The aim of this study was to determine the frequency of brainstem and cranial nerve involvement, except for olfactory and optic nerves, during MS attacks, and to investigate the rate of an available explanation for the cranial neuropathy findings by lesion localization on brain MRI. METHODS: Ninety-five attacks of 86 MS patients were included in the study. The patients underwent a complete neurological examination, and cranial nerve palsies (CNP) were determined during MS attacks.RESULTS: CNP were found as follows: 3rd CNP in 7 (7.4%), 4th CNP in 1 (1.1%), 5th CNP in 6 (6.3%), 6th CNP in 12 (12.6%), 7th CNP in 5 (5.3%), 8th CNP in 4 (4.2%), and 9th and 10th CNP in 2 (2.1%) out of 95 attacks. Internuclear ophthalmoplegia (INO) was detected in 5 (5.4%), nystagmus in 37 (38.9%), vertigo in 9 (6.3%), and diplopia in 14 (14.7%) out of 95 attacks. Pons, mesencephalon and bulbus lesions were detected in 58.7%, 41.5% and 21.1% of the patients, respectively, on the brain MRI. Cranial nerve palsy findings could not be explained by the localization of the lesions on brainstem MRI in 5 attacks; 2 of them were 3rd CNP (1 with INO), 2 were 6th CNP and 1 was a combination of 6th, 7th and 8th CNP. CONCLUSION: The most frequently affected cranial nerve and brainstem region in MS patients is the 6th cranial nerve and pons, respectively. A few of the MS patients have normal brainstem MRI, although they have cranial neuropathy findings in the neurologic examination

Özet

AMAÇ: Multipl sklerozlu hastalarda, beyin sapında manyetik rezonans görüntüleme (MRG) ile lezyon gösterilemediği halde klinik olarak kraniyal sinir tutulumu olabildiği bildirilmiştir. Bu çalışmanın amacı; multipl sklerozlu hastalarda atak dönemlerinde beyin sapının ve olfaktör ve optik sinirler haricindeki kraniyal sinirlerin tutulum sıklıklarını ve beyin sapındaki lezyon lokalizasyonu ile kraniyal nöropati bulgularının açıklanabilme oranlarını belirlemektir. YÖNTEMLER: Çalışmaya 86 multipl skleroz hastasının toplam 95 atağı alınmıştır. Bu atakların hepsinde hastaların nörolojik muayeneleri yapılmış ve kraniyal nöropatisi olanlar belirlenerek, kraniyal MRG görüntüleri incelenmiştir.BULGULAR: Doksan beş ataktan 7 (%7.4)’sinde üçüncü sinir, 1 (%1.1)’inde dördüncü sinir, 6 (%6.3)’sında beşinci sinir, 12 (%12.6)’sinde altıncı sinir, 5 (%5.3)’inde yedinci sinir, 4 (%4.2)’ünde sekizinci sinir, 2 (%2.1)’sinde dokuzuncu ve onuncu sinir tutulumu saptanmıştır. Beş (%5.4) atakta internükleer oftalmopleji, 37 (%38.9)’sinde nistagmus, 9 (%6.3)’unda vertigo ve 14 (%14.7)’ünde diplopi tespit edilmiştir. Pons, mezensefalon ve bulbusta lezyon görülme oranları sırasıyla %58.5, %41.5 ve %21.1’dir. Beş atakta kraniyal nöropati bulguları beyin MRG ile açıklanamamıştır; bunların ikisinde üçüncü kraniyal sinir tutulumu (bir hastada beraberinde internükleer oftalmopleji de vardı), ikisinde altıncı sinir tutulumu, birinde ise altı, yedi ve sekizinci sinir tutulumu mevcuttu.SONUÇ: Multipl skleroz hastalarında en sık etkilen kraniyal sinir altıncı sinir, en sık tutulan beyin sapı bölgesi ponstur. Hastaların küçük bir kısmında kraniyal nöropati bulgularına rağmen beyin sapı MRG normal olabilmektedir.
