Step-by-step explanation:
The 'batwing' pattern described in a radiological report of a chest radiogram is most consistent with pulmonary edema. This distinctive pattern, which resembles the wings of a bat spread out, is typically seen on a chest X-ray and indicates the presence of excess fluid in the air sacs of the lungs.
