Pasteur-Roudeau symptom is a name given in honor of the French scientists Georges Louis Pastor (1822 - 1895) and Gaston Roudot (1814 - 1901). The Pasteur-Rudo symptom, or in other words, “tangled shadow,” is a symptom that manifests itself in traumatic brain injury in children resulting from a short-term strong blow or bruise from a fall. This symptom was first described by these scientists.
When a medical diagnosis reveals the same type of body part or organ on a patient’s MRI, a detailed study of the object of study is required. The organ is assessed as normal and typical, but some tissues may be altered or show characteristic changes in shape, size or signal. Tests can also highlight abnormal areas in a sample, and finally can show objects and growths that are not part of the body they are looking at.
