Summary
This case report details a rare instance of mixed connective tissue disease (MCTD) presenting with acute polyradiculoneuropathy. Prompt corticosteroid treatment led to significant improvement in neurological deficits and laboratory findings.
Area of Science:
- Rheumatology
- Neurology
Background:
- Mixed connective tissue disease (MCTD) is an autoimmune disorder with overlapping features of systemic lupus erythematosus, scleroderma, and polymyositis.
- Neurological manifestations in MCTD are uncommon, with polyradiculoneuropathy being a particularly rare presentation.
Observation:
- A 23-year-old woman with clinical features suggestive of MCTD developed acute polyradiculoneuropathy.
- Neurological symptoms included gait disturbance, accompanied by fever, arthralgia, and headache.
- Diagnostic workup involved cerebrospinal fluid (CSF) analysis, electrophysiological studies, nerve and muscle biopsies, and magnetic resonance imaging (MRI).
Findings:
- The patient's presentation and diagnostic data confirmed a diagnosis of MCTD with acute polyradiculoneuropathy.
- Neurological deficits and laboratory abnormalities showed improvement following corticosteroid therapy.
Implications:
- This case highlights the importance of considering rare neurological complications in patients with MCTD.
- Early diagnosis and treatment with corticosteroids may lead to favorable outcomes in MCTD-associated polyradiculoneuropathy.
