Right-sided muscle atrophy is mainly considered to be related to myogenic factors and neurogenic factors.
1. Myogenic factors
(1) Congenital myopathy: for example, benign congenital myopathy, myotubular myopathy, etc., which can lead to muscle atrophy, weakness and other symptoms.
(2) Traumatic myopathy: for example, traumatic injury and contusion can lead to local muscle fracture, extrusion, ischemia, and then the symptoms of muscle atrophy.
(3) Others: for example, polymyositis, chronic alcoholic myopathy, progressive muscular dystrophy, etc., which can also trigger muscle atrophy.
2. Neurogenic factors
(1) Brain stem lesions: for example, brain stem tumor, meningitis and other diseases can lead to atrophy of facial, pharyngeal, tongue and chewing muscles.
(2) Cerebral and spinal neuropathy: cerebral and spinal neuritis, mononeuritis, nerve trauma and neurogenic progressive muscular dystrophy, and other diseases, can also trigger muscle atrophy.
Symptoms of muscle atrophy may also be other causes, the cause is relatively complex, it is recommended to consult a doctor to confirm the diagnosis, and follow the doctor’s instructions for treatment.
