An elderly male with tingly legs and a heavy heart: Persisting with the diagnosis!

Abstract

Pursuing a diagnosis despite a negative nerve biopsy report requires a strong clinical conviction. Paying attention to clinical details and a diligent review of medical records is needed to solve cases in which the diagnosis is not obvious despite numerous tests. We present once such case of an elderly man with chronic diarrhea, weight loss, and peripheral neuropathy and elaborate on a step by step basis on how the clinical thought process evolved after sifting through the reports of scan and tests done during his work up.
