CTICasesPulmonary Infarct (Mucor Infection)
Imaging findings
In a post-lung transplant patient, CT shows narrowing of the left main pulmonary artery at the suture line, a necrotic collection in the left lower lobe, and an abrupt cutoff of the left inferior pulmonary vein. There is also interlobular septal thickening (suggestive of primary graft dysfunction).
Key takeaways
Anastomotic stenosis can lead to complications like pulmonary infarction. In immunosuppressed transplant patients, necrotic areas can easily become infected with opportunistic angioinvasive fungi, such as Mucor.
