Diabetic lumbosacral radiculoplexus neuropathy, also known as diabetic lumbosacral plexopathy or diabetic amyotrophy, is a rare complication of diabetes mellitus. Due to its varied clinical presentation and wide differential, it may pose a diagnostic quandary in assessing patients with proximal asymmetrical lower limb weakness. We present the case of a 74-year-old female patient with a recent onset of falls and aim to discuss the aetiology, differentials, and treatment modalities in diabetic plexopathy.
