Here, we describe the case of a 45-year-old male with a history of recurrent sinusitis refractory to antibiotics, who presented to the emergency department with sinus congestion and dysphagia. Clinical examination revealed left lower motor neuron facial palsy and enlarged submandibular salivary glands. Despite obtaining negative results from various antibody panels, the patient exhibited elevated angiotensin-converting enzyme levels of 83 nmol/kg/min. Additionally, computed tomography chest scans revealed bilateral hilar and mediastinal lymph node enlargement, findings consistent with sarcoidosis. Otorhinolaryngology evaluation for dysphagia confirmed left vocal cord palsy. Following a negative infectious disease workup, submandibular salivary gland biopsy confirmed sarcoidosis. Treatment with mycophenolate mofetil and oral steroids led to gradual improvement in salivary gland swelling, dysphagia, and facial palsy. However, worsening left shoulder pain prompted further investigation, revealing winging of the left scapula on repeat examination. Magnetic resonance imaging (MRI) of the cervical spine revealed a 6-mm hyperintensity in the left dorsal cord at the C5 level, suggesting possible neurosarcoidosis vs. demyelinating disease. Subsequently, the patient was prescribed anti-tumour necrosis factor alpha inhibitor infliximab. Subsequent MRI of the cervical spine, conducted 6 months after initiating infliximab therapy, indicated resolution of the lesions. This positive outcome was supported by the patient's report of symptom improvement, notably reduced shoulder pain and improvement in left scapular winging. This case underscores the unusual co-occurrence of Bell's palsy and vocal cord palsy in the same patient, along with the potential contribution of neurosarcoidosis to the winged scapula. Additionally, it sheds light on the positive response of neurosarcoidosis to infliximab therapy.</p>","PeriodicalId":94146,"journal":{"name":"Modern rheumatology case reports","volume":" ","pages":"184-187"},"PeriodicalIF":0.9,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141082928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this case, while glucocorticoid tapering was difficult, the introduction of upadacitinib resulted in the remission of both atopic dermatitis and IgG4-RD without glucocorticoid dose escalation. Peripheral blood flow cytometry analysis showed that the proportions of activated non-Th1/Th17 cell subset (Th2 cells), follicular helper T cells, and plasmocytes were increased before upadacitinib therapy, but all normalised after treatment. Interleukin-4 and interleukin-21 signals are important for the differentiation of CD4+ T cells into type 2 helper T or B cells in the peripheral blood.
