Severe pulmonary vein stenosis in association with IgG4 gammopathy: An unusual case.

IgG4-related disease (IgG4-RD)is a multifactorial and systemic immune-mediated disease. Pulmonary vein stenosis related to IgG4 is a rare entity. We report a case of a 57-year-old male who presented with vague symptoms of weakness, easy fatigue, shortness of breathing, chest tightness, and occasional palpitations.

We report a case of a neurilemmoma that arose from the right arytenoid muscle adjacent to the arytenoid cartilage.
