Diaphragmatic paralysis can result from a variety of causes, broadly categorized into neurological, structural, and systemic conditions. Frequently, it is associated with tumors originating in the brainstem or cervical spinal cord injuries, often stemming from neck fractures. Other structural causes include tumors directly involving the diaphragm, such as lung tumors, or those in adjacent organs like the liver and stomach that impinge upon it. Traumatic injuries affecting the diaphragm can also lead to paralysis. Furthermore, diaphragmatic paralysis is observed in various neuromuscular and systemic disorders, including Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), muscular dystrophy, and central alveolar hypoventilation. Neuropathic conditions such as Guillain-Barré Syndrome, as well as certain thyroid and autoimmune diseases, can also manifest with diaphragmatic paralysis.
