CTICasesPost-Lobectomy Right Middle Lobe Syndrome
Imaging findings
CT chest post-right upper lobectomy shows complete collapse of the right middle lobe with thready pulmonary vessels and a thready, but open, right middle lobe bronchus containing secretions.
Key takeaways
Right middle lobe syndrome (chronic atelectasis) is a known complication post-right upper lobectomy. Altered anatomical relationships can cause stretching, narrowing, and mucous plugging of the middle lobe bronchus. It is typically managed conservatively if the bronchus is patent and the lobe is not infarcted/torsed.
