sult from aberrant budding from the ventral diverticulum, and are usually discovered in the posterior part of the mediastinum, along the right paratracheal wall (1, 2). Cysts that develop below the diaphragm, especially in the retroperitoneal region, are extremely rare (3, 4), and fewer than 50 cases have been reported in English language clinical literature to date. To the best of our knowledg...

INTRODUCTION Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen). So far, 70 cases of cervical localization of bronchog...

BACKGROUND A mediastinal air cyst is a rare computed tomography (CT) finding. Once the lesion is identified, it is difficult to diagnose and treat. Meanwhile, bronchial diverticula have been reported as a CT finding observed in certain pulmonary pathologic conditions. We encountered the case of an enlarged mediastinal air cyst accompanied with bronchial diverticula and upper lobe-dominant fibro...

OBJECTIVE To analyze patterns of central lymph node (LN) metastasis to specific compartments in the neck and predictive factors of contralateral paratracheal LN metastasis in patients who underwent prophylactic bilateral central LN dissection for papillary thyroid cancer (PTC). STUDY DESIGN Prospective study. SETTING Multitertiary centers. SUBJECTS AND METHODS One hundred forty consecutiv...

IMPORTANCE Central neck dissection (CND) is considered an imperative part of the treatment of patients with high-risk, well-differentiated thyroid carcinoma. OBJECTIVE To examine the presence of lymphatic tissue and/or metastatic nodes in the upper part of the paratracheal region to determine the need to dissect this region as part of a paratracheal neck dissection. DESIGN, SETTING, AND PAR...
