Abstract

This report describes a rare case of livedoid vasculopathy (LV) with sensory and motor neurologic deficits. A 46-year-old woman who had been diagnosed with LV developed acute left-foot drop. An electrodiagnostic study showed multiple mononeuropathy involving both the common peroneal and sural nerves, primarily on the left side. Nerve biopsy findings showed intravascular thrombosis in the perineurium and extensive infarct of the peripheral nerve. The patient was prescribed continuous anticoagulants, which resulted in a good clinical outcome. LV associated with multiple mononeuropathy is a rare condition, and the exact pathophysiologic mechanism of nerve involvement and treatment for neurologic deficits remain unclear. The histologic findings in the present case support the possibility that the peripheral neuropathy related to LV was primarily derived from an ischemic injury rather than inflammation. Continuous anticoagulant use could be helpful in the neurologic recovery of LV patients with multiple mononeuropathy.
