Pulse Steroids for Idiopathic Plexopathy

Diagnostic Workup and Treatment

The American Society of Clinical Oncology recommends pulse methylprednisolone therapy for severe immune-mediated plexopathies, which has been extrapolated to idiopathic cases 1
Neurologic consultation is recommended to confirm diagnosis and rule out other causes 1
MRI of the affected plexus region is recommended to rule out compressive lesions and evaluate for nerve root enhancement/thickening 1
Electrodiagnostic studies (NCS and EMG) are recommended to characterize the plexopathy 1
Pulse methylprednisolone 1g daily for 3-5 days intravenously is recommended for moderate to severe cases 1
Oral prednisone taper over 4-6 weeks is recommended after pulse methylprednisolone therapy 1
The American College of Physicians may recommend considering gabapentin, pregabalin, or duloxetine for neuropathic pain management, although the specific guideline is not mentioned in the article, the Journal of Clinical Oncology does 1
Frequent neurological examinations are recommended to assess treatment response 1
Monitoring for steroid-related adverse effects is recommended 1
Failing to provide adequate pain management alongside anti-inflammatory treatment should be avoided 1
Not considering alternative diagnoses if there is poor response to treatment should be avoided 1
