Mit der zunehmenden Anzahl von CT-Untersuchungen des Thorax steigt auch die Prävalenz
zufällig entdeckter Lungenrundherde. Während das Hauptziel der Abklärung eines inzidentellen
Lungenrundherdes darin besteht, die Dignität des Rundherdes zu bestimmen, müssen die
Risiken
durch unnötige diagnostische Verfahren minimiert werden. Fortschritte und neue Technologien
in
der Bildgebung sowie bei der histologischen Probengewinnung ermöglichen es, diese
Ziele zu
erreichen.
Abstract
As the number of CT examinations of the lungs increases, so does the prevalence of
incidentally discovered pulmonary nodules. While most lung nodules are benign, the
risk of
malignancy significantly rises with the presence of risk factors and specific imaging
features. Upon encountering an incidental nodule, efforts should focus on achieving
an
accurate pathological diagnosis, particularly to ascertain malignancy while minimizing
the
risks associated with unnecessary diagnostic procedures. A comprehensive understanding
of the
typical characteristics and behavior of malignant lung nodules, along with a detailed
patient
history and standardized clinical and imaging risk assessment, is crucial for determining
the
optimal diagnostic approach. Additionally, the decision regarding histologic confirmation
should consider the patient's comorbidities, preferences, and the examiner's expertise.
Emerging sampling technologies provide methods for addressing peripheral lung nodules
with
minimal risk of complications.
