Huge Tracheal Diverticulum in a Patient with Mounier-Kuhn Syndrome

Tracheal diverticulum is a rare benign entity. Tracheobronchomegaly (TBM), also known as Mounier-Kuhn syndrome, is a rare disorder characterized by marked dilation of the trachea and main bronchi, associated with thinning or atrophy of the elastic tissue. Because of the weakened trachea and increased intraluminal pressure related to chronic cough, some patients may develop mucosal herniation leading to tracheal diverticulosis. We report the case of a patient with TBM with a huge tracheal diverticulum, diagnosed by bronchoscopy and computed tomography with three-dimensional reconstruction. To our knowledge this is the largest tracheal diameter described in a patient affected by this syndrome.

Unexpected Complication of a Multinodular Goitre

Multinodular goitre is the most common thyroid gland disorder. It can cause hyperthyroidism and mechanical complaints such as tracheal compression or dysphagia. We report a unique case of a patient with a toxic multinodular goitre presenting with a deep venous thrombosis of the left arm due to direct local compression of blood flow.
