About this document
Hilum Overlay Sign in Chest Imaging by mihaela is a document available to read on EtoBox.
The document discusses the hilum overlay sign seen on chest imaging. This sign occurs when a mass located in the mediastinum causes an abnormal convexity over the hilum while still allowing visualization of the pulmonary arteries through the mass. Common causes include anterior mediastinal masses like thymoma or lymphoma. The document provides examples of the sign on chest x-rays and CT scans and discusses distinguishing features from other similar signs.
