Chronic lymphedema due to constriction

We describe an unusual presentation of lymphedema due to constriction of the left upper extremity in a 71-year-old woman. The patient reported an onset of left upper extremity swelling 6 months prior to presentation, after she slept wearing a magnetic health bracelet. However, she was not accurately diagnosed until she visited our department. The diagnostic workup included a history and laboratory and radiologic findings, which were all normal except for the swollen upper extremity and findings on lymphoscintigraphy. She was diagnosed as suffering from chronic lymphedema due to constriction that only affected her left arm. She underwent complete decongestive therapy and achieved mild improvement of her swelling.
