The normal right paratracheal stripe is a thin < 4 mm soft tissue density line that forms where the soft tissue density right tracheal wall contacts the air density right lung. Malignancy is a common cause of stripe thickening.

Chest X-ray revealed a smooth mass at the right tracheobronchial angle (figure 1). During right heart catheterisation, there was difficulty in negotiating the wire from the IVC to the right atrium. On manipulation, the wire took a course from the IVC to the SVC to the right atrium.

Right paratracheal masses are often the consequence of primary or metastatic malignancies in the region. Paratracheal masses can cause a wide range of symptoms in patients, depending on their size, location, and type. Typical signs might include: Persistent coughing. Breathing difficulties or wheezing. Changes in voice or hoarseness.

2008年9月15日 · A 79-year-old woman was referred to the pulmonary clinic for evaluation of a right paratracheal mass identified on a chest radiograph obtained for cancer monitoring. She was a never-smoker who had been treated 15 years before for early-stage breast cancer without lymph node involvement with a right mastectomy.

2022年12月13日 · Mediastinal tumors include thymomas, lymphomas, germ cell tumors and cysts, among others. They’re masses of cells that appear in the space between your lungs, called the mediastinum. These tumors may be malignant (cancerous), but they’re usually benign (noncancerous). Surgery is the most common treatment.

On chest radiograph, the dilated azygos arch may be misinterpreted as a right paratracheal neoplasm, while the dilated azygos and hemiazygos veins in the paravertebral location may be mistaken for a posterior mediastinal neoplasm.

The presumptive diagnosis for the right paratracheal mass was likely due to a nondeveloped right upper lung with associated scarring and atelectasis. The pathology report later confirmed the finding as there was no indication of malignancy or fungal infection.
