What is left suprahilar infiltrate?

Left suprahilar infiltrate refers to an abnormal accumulation of fluid or cells in the area above the hilum of the left lung, which can be seen on imaging studies like chest X-rays or CT scans. This infiltrate may indicate various conditions, such as pneumonia, pulmonary edema, or malignancy. The hilum is the region where blood vessels and bronchi enter and exit the lungs, and infiltrates in this area can affect lung function and may require further investigation to determine the underlying cause.
