What percentage of Myasthenia Gravis patients have thymic hyperplasia?

In Myasthenia Gravis (MG), thymic hyperplasia is a common finding, especially among patients with autoimmune disease. Research indicates that approximately 75% of individuals diagnosed with Myasthenia Gravis exhibit thymic hyperplasia. This hyperplasia is characterized by an enlargement of the thymus gland, which is believed to play a role in the abnormal immune response, leading to the production of autoantibodies against acetylcholine receptors. This connection highlights the significance of the thymus in the pathophysiology of the disease.

Other percentages, such as 100%, 50%, or 25%, do not represent the current clinical understanding of thymic hyperplasia in patients with Myasthenia Gravis. Hence, the answer aligns with evidence suggesting that a significant majority, specifically around 75%, of Myasthenia Gravis patients present this condition.
