Pitfall - 2
Take-home massage GGA is a nonspecific finding. When diffuse GGA is observed, radiologists should… I. Pay attention to the additional radiographic findings and clinical features. II. Keep in mind that pulmonary edema is the most common cause of diffuse GGA. III. Also consider the possibility of viral pneumonia when infections are suspected. PCP or CMV pneumonia are the common life-threatening infectious complications in immunocompromised patients.
