Concurrent transverse myelitis and acute inflammatory demyelinating polyneuropathy.

BMJ Case Rep

Neurology Department, Barwon Health, Geelong, Victoria, Australia.

Published: May 2024

A woman in her 40s presented with thoracic banding dysaesthesia and lower motor neuron weakness. Spinal imaging revealed a short segment of transverse myelitis and neurophysiology was suggestive of concurrent acute inflammatory demyelinating polyneuropathy. The patient improved with consecutive intravenous immunoglobulin and methylprednisolone treatment. Acute inflammatory demyelinating polyneuropathy is a progressive immune-mediated peripheral neuropathy which responds to intravenous immunoglobulin or plasmapheresis, whereas transverse myelitis is a central inflammatory syndrome usually treated with corticosteroid. We highlight differentiating features of the clinical presentation and the utility of investigations such as neurophysiology and MRI along with a review of treatment and the role for corticosteroid therapy.

Here we present a rare case of hemorrhagic longitudinally extensive transverse myelitis (LETM) as a first presentation of Neuromyelitis Optica Spectrum Disorder. Even though the patient received aggressive treatment, he showed no significant improvement. Our case highlights the importance of prompt intervention in the case of hemorrhagic myelitis and the diagnostic challenges of hemorrhagic LETM.

Article Synopsis
  • Acute transverse myelitis (ATM) is a serious neurological disorder involving spinal cord inflammation, leading to sensory, motor, and autonomic issues.
  • A 29-year-old woman experienced severe lower limb weakness, urinary issues, and sensory loss, with MRI confirming ATM and HCV infection present in her blood.
  • The case underscores the need for awareness of ATM as a possible complication of hepatitis C, especially when there is infective endocarditis (IE) involved, as confirmed by blood cultures showing bacteria linked to IE.

Mumps Myelitis-A Rare Cause of Myelitis.

Am J Trop Med Hyg

January 2025

Medanta, The Medicity, Gurugram, India.

This report presents a rare case of acute transverse myelitis (ATM) after mumps infection in a 33-year-old male. Symptoms included fever, parotid and scrotal swelling, and subsequent sensory-motor paraparesis. Magnetic resonance imaging revealed long-segment spinal cord hyperintensity, and cerebrospinal fluid analysis showed pleocytosis and elevated protein, with positive mumps virus antibodies.

Brucellosis mainly affects the musculoskeletal system with neurological manifestations observed in < 5% of all cases. This report outlines a unique case of neurobrucellosis that resulted in acute transverse myelitis (TM) with absent deep reflexes and negative Wright's reaction. In endemic regions, neurobrocellosis should be considered as a potential etiology of acute TM.

This case report describes a woman in her 50s with a rare coexistence of neuromyelitis optica spectrum disorder (NMOSD) and myasthenia gravis (MG), highlighting the diagnostic challenges and therapeutic considerations. Initially diagnosed with acetylcholine receptor antibody-positive MG, she later developed progressive visual impairment, leading to a diagnosis of NMOSD. Rituximab treatment was effective in managing both conditions, demonstrating the benefits of targeted therapies in reducing complications related to polypharmacy.
