IgG4-assoziierte Erkrankung des Mediastinums

A case of

IgG4-related anterior mediastinal sclerosing disease coexisting with autoimmune pancreatitis. Anterior mediastinal mass. Chest computed tomography (CT) revealed a 2.5-cm well-defined homogenous mass in the anterior mediastinum at the time of diagnosis with autoimmune pancreatitis (a), and the tumor decreased in size to 2 cm on CT with oral steroid treatment 6 years ago (b). The tumor had regrown to 3 cm at the time of referral to our department on CT (c, d), and positron emission tomography showed a high maximum standardized uptake of 3.6 by the anterior mediastinal mass lesion (e)

Isolated

middle mediastinal mass associated with immunoglobulin G4-related disease. Preoperative imaging. a Chest X-ray showed an abnormal mass in the left mediastinum (yellow arrowheads). b Enhanced computed tomography of lung field (yellow arrowheads). c Enhanced computed tomography of mediastinal field; the left mediastinal mass was a homogenous round-shaped 3.8 × 2.4 cm in diameter (yellow arrowheads)
