A Rare Case of Acute Transverse Myelitis (ATM) and Acute Motor and Sensory Axonal Neuropathy (AMSAN) Overlap

Area of Science:

• Neuroscience
• Neurology
• Clinical Medicine

Background:

• Acute transverse myelitis (ATM) and Guillain-Barre syndrome (GBS) are distinct neurological disorders.
• GBS has several subtypes, including acute motor axonal neuropathy (AMAN) and acute motor and sensory axonal neuropathy (AMSAN).
• Overlap syndromes between ATM and GBS are known but challenging to diagnose due to variable presentations.

Observation:

• A middle-aged male patient presented with symptoms suggestive of both ATM and GBS.
• Diagnostic workup revealed a concomitant diagnosis of ATM and the AMSAN subtype of GBS.
• This specific combination of ATM and AMSAN is exceptionally rare in reported literature.

Findings:

• The case confirms the possibility of concurrent ATM and GBS, specifically the AMSAN subtype.
• The patient's presentation underscores the diagnostic complexity of these overlapping conditions.
• This finding expands the known spectrum of GBS and ATM overlap syndromes.

Implications:

• Clinicians should consider rare overlap syndromes when faced with complex neurological presentations.
• Increased awareness of ATM and AMSAN co-occurrence may improve diagnostic accuracy.
• Further research into the pathophysiology and management of such rare neurological overlaps is warranted.
