Overview

Transverse myelitis must be differentiated from other diseases that cause hypotonia, muscle weakness, or paralysis such as: Adult botulism, infant botulism, Guillian-Barre syndrome, Eaton Lambert syndrome, myasthenia gravis, electrolyte disturbance, organophosphate toxicity, tick paralysis, stroketetrodotoxin poisoning, poliomyelitis, neurosyphilis, muscular dystrophy, multiple sclerosis exacerbation, amyotrophic lateral sclerosis and inflammatory myopathy.

Differential Diagnosis

Transverse myelitis must be differentiated from other diseases that may cause hypotonia, muscle weakness, or paralysis:[1][1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]

Diseases History and Physical Diagnostic tests Other Findings
Motor Deficit Sensory deficit Cranial nerve Involvement Autonomic dysfunction Proximal/Distal/Generalized Ascending/Descending/Systemic Unilateral (UL)

Tick paralysis (Dermacentor tick)[22] + - - - Generalized Ascending BL Insidious Clinical diagnosis: physical exam & history - History of outdoor activity in Northeastern United States. The tick is often still latched to the patient at presentation (often in head and neck area)
Tetrodotoxin poisoning[23] + - + + Generalized Systemic BL Sudden Clinical diagnosis: physical exam & dietary history - History of consumption of puffer fish species.
Stroke[24] +/- +/- +/- +/- Generalized Systemic UL Sudden MRI +ve for ischemia or hemorrhage MRI Sudden unilateral motor and sensory deficit in a patient with a history of atherosclerotic risk factors (diabetes, hypertension, smoking) or atrial fibrillation.
Poliomyelitis[25] + + + +/- Proximal > Distal Systemic BL or UL Sudden PCR of CSF Asymmetric paralysis following a flu-like syndrome.
Neurosyphilis[26][16] + + - +/- Generalized Systemic BL Insidious MRI & Lumbar puncture CSF VDRL-specifc

History of unprotected sex or multiple sexual partners.

History of genital ulcer (chancre), diffuse maculopapular rash.

Muscular dystrophy[28] + - - - Proximal > Distal Systemic BL Insidious Genetic testing Muscle biopsy Progressive proximal lower limb weakness with calf pseudohypertrophy in early childhood. Gower sign positive.
Multiple sclerosis exacerbation[29] + + + + Generalized Systemic NL Sudden CSF IgG levels

(monoclonal)

Clinical assessment and MRI [30] Blurry vision, urinary incontinence, fatigue
Amyotrophic lateral sclerosis[31] + - - - Generalized Systemic BL Insidious Normal LP (to rule out DDx) MRI & LP Patient initially presents with upper motor neuron deficit (spasticity) followed by lower motor neuron deficit (flaccidity).
Inflammatory myopathy[32] + - - - Proximal > Distal Systemic UL or BL Insidious Elevated CK & Aldolase Muscle biopsy Progressive proximal muscle weakness in 3rd to 5th decade of life. With or without skin manifestations.
