Ischemic monomelic neuropathy (IMN) is a rare type of acute axonal neuropathy which results from ischemia of multiple nerves in affected limb. The electroneuromyography is useful in detecting characteristic features of this neuropathy. It usually occurs after vascular interventions. Here, we present the first case who has IMN secondary to lung cancer and/or chemo-therapy and aim to draw attention to this infrequently recognized entity.
