Hemihyperplasia - symptoms and diagnostics on the example of a clinical case

Abstract

In 1925 Sympson coined the term "hemihypoplasia", which is completely different from the symptom of hemiotrophy (l). Neurogenic hemihypoplasia is characterized by a symmetrical decrease in one half of the body, face, skeleton and soft tissues, while without disturbing the nervous system (with the exception of rare cases of lesions). Right-handedness or left-handedness, as a functional asymmetry, is normative. At the same time, morphological asymmetry implies a difference in the length and volume of the limb. The clinical symptoms of morphological asymmetries are varied, from uniform side reduction to cross asymmetries. Most scientific literary sources note this congenital anomaly, the reasons are poorly understood (l). The border between the healthy and the affected side runs strictly along the midline, in the form of asymmetry of the skeleton, soft tissues and internal organs. A frequent question for medics is which side is healthy, smaller or larger? In such cases, a slight motor difference comes to the rescue, the worst side is weaker, the jerk reflex is worse, the preference for the grasping reflex, the trampling of shoes on one side. Vegetative asymmetry is usually manifested by thinning of the skin, skin color (lighter or darker). Ripple difference between sides.
