What is a suprahilar nodule?

A suprahilar nodule is a small, abnormal growth or mass located above the hilum of the lung, which is the area where blood vessels and airways enter and exit the lungs. These nodules can be detected through imaging studies like chest X-rays or CT scans and may indicate various conditions, including infections, inflammatory processes, or malignancies. The clinical significance of a suprahilar nodule often depends on its size, characteristics, and the patient's medical history, necessitating further evaluation for accurate diagnosis.
