Knowledge of anatomical variations can aid the clinical practitioner in avoiding iatrogenic injury during invasive procedures. Here, we present an unusual finding of the median cubital vein and its relationship with bicipital aponeurosis. This case and relevant reports from the literature are reviewed. Physicians or other health care providers who perform procedures in the cubital fossa, such as venipuncture or vascular access, should be aware of such an anatomical variation.
