Hepatomegaly, also known as Wilson’s disease, is an autosomal recessive disorder that results in chronic deposition of copper in different parts of the body (liver, basal ganglia, kidneys, cornea, bone tissue, etc.) due to impaired copper metabolism, leading to liver cirrhosis, softening and degeneration of the basal ganglia (especially the nucleus accumbens), kidney damage, and eye lesions. Most cases develop between the ages of 7 and 12 years, with the youngest being 2-3 years old and the oldest reaching adulthood, with liver disease as the first symptom in children under 10 years old and neurological symptoms in those over 10 years old. This disease is one of the few genetic diseases that can be effectively treated symptomatically, and its efficacy is closely related to the time of starting treatment, adherence to long-term medication, and a low-copper diet.
