Comparison of MRI findings of hypothalamic-optic chiasmatic gliomas and craniopharyngiomas.

Background: Differential diagnosis of hypothalamic-optic chiasmatic gliomas (HOCGs) and craniopharyngiomas on magnetic resonance imaging (MRI) can be quite challenging.

Purpose: To compare the MRI features of HOCGs and cranipharyngiomas.

Material And Methods: Patients diagnosed with HOCG or craniopharyngioma in histopathological evaluation between 2012 and 2022 and who underwent preoperative contrast-enhanced brain MRI were included.

Tracheobronchial Amyloidosis: A Case Report.

We report a case of an incidentally found tracheobronchial amyloidosis in an asymptomatic patient. A elderly male was admitted to the hospital for an aortic valve repair workup, and was incidentally found to have tracheobronchial abnormalities on chest CT. The diagnosis of tracheobronchial amyloidosis was confirmed by histopathological exam.
