CTICasesPulmonary Mucormycosis with Pulmonary Artery Invasion
Imaging findings
Chest radiograph reveals a new left apical nodule. CT demonstrates a dense focal nodule with a surrounding ground-glass halo, adjacent septal edema, and an irregular deformity of the adjacent left pulmonary artery indicating direct erosion and invasion.
Key takeaways
Mucormycosis is a highly aggressive, angioinvasive fungal infection that occurs in immunocompromised hosts, such as neutropenic patients with hematologic malignancies. Direct invasion of major vascular structures like the pulmonary artery is a critical prognostic finding that often precludes surgical resection due to high risk and anatomical complexity.
