Mononeuropathy due to vincristine toxicity

Area of Science:

• Neurology
• Oncology
• Pharmacology

Background:

• Vincristine sulfate is a widely used chemotherapy agent.
• Vincristine is a known neurotoxin, with peripheral neuropathy being a common side effect.

Observation:

• Peripheral neuropathy from vincristine typically presents as a symmetrical, mixed, sensory-motor type.
• This report describes a case that illustrates another feature of vincristine neurotoxicity.

Findings:

• The study identifies mononeuropathy as a potential manifestation of vincristine neurotoxicity.
• This contrasts with the more commonly reported symmetrical peripheral neuropathy.

Implications:

• Physicians should be aware of mononeuropathy as a possible sign of vincristine neurotoxicity.
• Early recognition and diagnosis of this neurological complication can guide treatment adjustments.
