Zusammenfassung
Die organisierende Pneumonie (OP) tritt sowohl idiopathisch auf („kryptogen organisierende
Pneumonie”) als auch als Folge unterschiedlichster Auslöser („sekundär organisierende
Pneumonie”). Häufige Trigger sind Infektionen, Medikamente, Kollagenosen, chronisch
entzündliche Darmerkrankungen, Organtransplantationen und Bestrahlungen im Thorakalbereich.
Die vorliegende Arbeit gibt einen Überblick über die histopathologischen, klinischen
und CT-morphologischen Charakteristika der OP. Hierbei werden sowohl die klassischen,
bildgebenden Zeichen (periphere oder peribronchovaskuläre Konsolidierungen und Milchglastrübungen)
als auch atypische Morphologien (Noduli, Crazy Paving, Linien und Bänder, perilobuläre
Konsolidierungen und das Reversed Halo Zeichen) vorgestellt.
Abstract
Organizing pneumonia (OP) occurs without any identifiable cause (”cryptogenic organizing
pneumonia”) as well as secondary to a multitude of disorders of various origins (”secondary
organizing pneumonia”). Possible triggers are infections, drugs, collagen vascular
disease, inflammatory bowel disease, transplantations, and radiation directed to the
chest. The present manuscript provides an overview of the histopathological, clinical
and CT imaging features of OP. Classic CT morphologies (peripheral and peribronchovascular
consolidations and ground glass opacities) and atypical imaging features (nodules,
crazy paving, lines and bands, perilobular consolidations and the reversed halo sign)
are discussed.
