What is hilum overlay sign?

The hilum overlay sign is a radiological sign observed on chest X-rays or CT scans, indicating that a lung mass is located in the hilum or is adjacent to it. This sign is characterized by the visibility of the vascular structures at the hilum, which helps differentiate between a true hilar mass and an adjacent lesion. When the hilum structures remain visible, it suggests that the mass is likely separate from the hilum itself, aiding in the diagnosis of lung pathology.
