Rationale:
Mixed connective tissue disease (MCTD) refers to an overlapping condition of different autoimmune disorders such as systemic lupus erythematosus, cutaneous systemic sclerosis, rheumatoid arthritis, polymyositis, and dermatomyositis. However, MCTD manifesting as transverse myelitis is extremely rare. Herein, we report a case of MCTD with both central and peripheral nervous system involvement.
Patient Concerns:
We describe and discuss the clinical findings and management of a 36-year-old man presented with a 2-week history of sudden bilateral lower-limb paralysis and dysuresia. Further investigation of his medical history showed a 6-month history of autoimmune symptoms.
Diagnoses:
The patient was diagnosed with MCTD, transverse myelitis, mononeuritis multiplex, and multiple lacunar infarctions.
Interventions:
A combination of low-dose methylprednisolone (40 mg/d) and hydroxychloroquine sulfate (400 mg/d) was administered.
Outcomes:
After treatment, the symptoms were significantly improved. The patient recovered well after 1 year follow-up and the sequela was urinary incontinence and grade 4/5 lower-extremity muscle strength.
Lessons:
MCTD with multiple neurological complications is extremely rare and poses diagnostic and therapeutic challenges. Our experience suggests a combination of low-dose corticosteroids and hydroxychloroquine sulfate may be an effective therapeutic approach.

01:11Introduction to Connective Tissues
01:30Classification of Connective Tissues
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense....
01:20Embryonic Connective Tissues
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development.
01:13Dense Connective Tissue
Dense Regular Connective Tissue
In dense regular connective tissue, fibers are arranged parallel to each other, enhancing its tensile strength and resistance to stretching in the direction of the fiber orientations. Ligaments and tendons are made of dense regular...
01:17Functions of Connective Tissues
Hard connective tissues, such as bones and cartilage, provide structure and support to the body.
01:26Loose Connective Tissue
Adipose Tissue
Adipose tissue consists primarily of fat storage cells called adipocytes and little extracellular matrix. A large number of capillaries present within adipose tissue allow rapid mobilization of lipid molecules. White adipose tissue is...
