Adjunctive Role of Pulmonary Angiography in Differentiating Invasive Mold Pneumonia from Bacterial Pneumonia.

In this retrospective study over eight years involving 25 immunocompromised adults, computed tomography pulmonary angiography (CTPA) demonstrated vascular invasion sign in 80% of proven or probable invasive mold pneumonia (IMP) cases (12/15), while absent in all bacterial pneumonia cases (0/10). These findings suggest that angioinvasion-related features on CTPA may serve as a valuable diagnostic adjunct in differentiating IMP from bacterial pneumonia in high-risk population.
