Video-assisted thoracoscopic surgery can help enable the complete resection of a mediastinal tumor caused by immunoglobulin G4-related disease and avoid the need for postoperative medication: A case report
Immunoglobulin (Ig) G4-related disease has various clinical signs and symptoms, and steroidal therapy with corticosteroids has been found to be effective for treatment. Few cases of IgG4-related disease associated with paravertebral tumor have been reported, and there have been no reports on complete resection of such a tumor. Here, we report a case of IgG4-related disease associated with a paravertebral tumor that was successfully resected without the need for postoperative medication. An 84-year-old woman was admitted to our hospital with a paravertebral tumor. She underwent thoracoscopic surgery, and pathological examination of the tumor specimen revealed that the tumor resulted from IgG4-related disease. After resection, there was no need for postoperative medication. Our case indicates the rare possibility of a paravertebral tumor associated with IgG4-related disease and the potential for complete resection as a treatment for such a tumor.
