IgG4-related mediastinitis is a rare condition that is characterized by inflammation of the mediastinum, the area between the lungs in the chest. It is caused by an accumulation of IgG4-positive plasma cells and is associated with other IgG4-related diseases. Symptoms may include chest pain, difficulty breathing, and coughing. Treatment typically involves corticosteroids and other immunosuppressive medications.

The most common symptoms of IgG4-related mediastinitis are chest pain, difficulty breathing, coughing, and fever. Other symptoms may include fatigue, night sweats, weight loss, and swollen lymph nodes in the neck or chest.

IgG4-related mediastinitis is an autoimmune disorder caused by an overproduction of IgG4 antibodies. It is believed to be caused by an abnormal immune response to an unknown antigen. Other possible causes include infections, medications, and environmental exposures.

The main treatment for IgG4-related mediastinitis is corticosteroid therapy. This involves taking a high dose of oral corticosteroids for several weeks to reduce inflammation and reduce the size of the mass. Other treatments may include surgery to remove the mass, radiation therapy, or immunosuppressive medications. In some cases, a combination of treatments may be used.
