What are possible differentials?
These appearances are nonspecific and have a broad differential, which would include atypical infections (such as tuberculosis), sarcoidosis, and metastatic disease. The sellar mass requires further assessment with MRI.
Apart from prominent and nonspecific submandibular lymph nodes, the remainder of the neck lymph nodes are not abnormally enlarged and do not have suspicious imaging features.
There are prominent mediastinal and bilateral hilar lymph nodes, as well as a few scattered pulmonary centrilobular nodules. There are no features of interstitial involvement.
There is an enhancing mass involving the sella and suprasellar region.
