It begins at the base of the skull and terminates in the superior mediastinum
A method for inspection and tissue biopsy in the superior mediastinum
For example, thymic extension into the superior mediastinum
in patients with thymic hyperplasia and neurofibromas can both show FDG-avidity on the PET scan (Figure 18).

with compression of the left main bronchus.
However, additional parathyroid glands may be located elsewhere such as in the neck or within the thymus in the superior mediastinum
A contrast-enhanced computed tomographic (CT) scan of the neck and chest showed cervical subcutaneous emphysema, pneumomediastinum, and multiple pockets of accumulated turbid fluid over the neck, superior mediastinum
, and bilateral pleural spaces (Fig.
Contrast-enhanced computed tomography (CT) demonstrated a low-attenuation mass arising from the floor of the neck and tracking into the superior mediastinum
