Clinical imaging plays a crucial role in early detection and diagnosis of invasive fungal diseases (IFD). Volumetric high-resolution computed tomography (CT) is the preferred method for lung imaging, providing valuable diagnostic information. Certain radiologic patterns, such as the halo sign and reversed halo sign, can help differentiate between invasive pulmonary aspergillosis and pulmonary mucormycosis.
Background. Clinical imaging in suspected invasive fungal disease (IFD) has a significant role in early detection of disease and helps direct further testing and treatment. Revised definitions of IFD from the EORTC/MSGERC were recently published and provide clarity on the role of imaging for the definition of 'PD. Here, we provide evidence to support these revised diagnostic guidelines. Methods. We reviewed data on imaging modalities and techniques used to characterize IFDs. Results. Volumetric high-resolution computed tomography (CT) is the method of choice for lung imaging. Although no CT radiologic pattern is pathognomonic of IFD, the halo sign, in the appropriate clinical setting, is highly suggestive of invasive pulmonary aspergillosis (IPA) and associated with specific stages of the disease. The ACS is not specific for IFD and occurs in the later stages of infection. By contrast, the reversed halo sign and the hypodense sign are typical of pulmonary mucormycosis but occur less frequently. In noncancer populations, both invasive pulmonary aspergillosis and mucormycosis are associated with atypical nonnodular presentations, including consolidation and ground-glass opacities. Conclusions. A uniform definition of IFD could improve the quality of clinical studies and aid in differentiating IFD from other pathology in clinical practice. Radiologic assessment of the lung is an important component of the diagnostic work-up and management of IFD. Periodic review of imaging studies that characterize findings in patients with IFD will inform future diagnostic guidelines.
