The Batwing pattern observed in X-rays indicates which condition?

The Batwing pattern seen in X-rays is a radiological term typically associated with pulmonary edema. This pattern reflects the distribution of fluid in the lungs, particularly in cases such as congestive heart failure. In pulmonary edema, fluid accumulates in the interstitial spaces and alveoli, leading to a characteristic appearance on imaging. The Batwing pattern occurs when there is bilateral opacification of the lung fields that resemble the wings of a bat, usually prominent in the central portions and sparing the peripheral regions of the lungs. This specific pattern helps clinicians identify pulmonary edema as a potential diagnosis and distinguish it from other respiratory conditions that present differently on imaging.
