Necrotizing angiopathy presenting with multifocal conduction blocks.
We describe conduction block as an unusual electrophysiologic manifestation in a patient with necrotizing angiopathy. The patient developed subacute symptoms over a 1-month period consisting of progressive pain, tingling, and weakness of the lower extremities. Physical examination revealed a pattern consistent with a polyneuropathy. Electrodiagnostic studies provided evidence of a conduction block in the left ulnar nerve. Pathologic studies confirmed the process to be a necrotizing angiopathy. This report establishes the role of conduction block in human nerve ischemia.
