Anemia-induced Claudication Mimicking Lumbar Spinal Stenosis

Anemia is not known to cause intermittent claudication. We herein present the case of a 74-year-old male patient with intermittent claudication, in whom the primary symptom was severe iron-deficiency anemia. The characteristics of claudication mimicked a neurogenic disorder, but lumbar magnetic resonance imaging ruled out lumbar spinal stenosis, and the symptoms resolved after the anemia improved. This case highlights the need to consider anemia in the differential diagnosis of patients presenting with intermittent neurogenic claudication. A comprehensive evaluation, including tests to rule out anemia, is crucial for making an accurate diagnosis and carrying out the appropriate management of intermittent claudication.
