Benigne fokale Leberläsionen

A profound knowledge of the various benign focal hepatic lesions and selection of the most suitable radiological examination modality is essential for achieving an accurate characterization of a hepatic lesion and in turn will determine the further patient management. This will avoid unnecessary agitation to both patient and the referring clinician and limits time-consuming, costly and risky biopsies to an absolute minimum. The following article will discuss the typical and atypical appearances of the most frequent and clinically relevant benign focal hepatic lesions with ultrasound, computed tomography and magnetic resonance imaging.ZusammenfassungEine genaue Kenntnis des breiten Spektrums benigner fokaler Leberläsionen und der geeigneten radiologischen Untersuchungsmethode ist essenziell, um eine sichere Diagnose bzgl. der Dignität und damit das weitere Vorgehen bestimmen zu können. Damit wird eine unnötige Verunsicherung des Patienten und des behandelnden Arztes vermieden, und invasive, eventuell mit Komplikationen assoziierte Biopsien sowie zeit- und kostenintensive Verlaufskontrollen können reduziert werden.Der folgende Artikel erläutert die häufigsten und klinisch wichtigsten benignen fokalen Leberläsionen und deren typisches und atypisches Erscheinen in den 3 häufig verwendeten bildgebenden Verfahren Sonographie, Computertomographie und Magnetresonanztomographie.AbstractA profound knowledge of the various benign focal hepatic lesions and selection of the most suitable radiological examination modality is essential for achieving an accurate characterization of a hepatic lesion and in turn will determine the further patient management.

Peritoneum and mesenterium. Radiological anatomy and extent of peritoneal diseases

The abdominal cavity is subdivided into the peritoneal cavity, lined by the parietal peritoneum, and the extraperitoneal space. It extends from the diaphragm to the pelvic floor. The visceral peritoneum covers the intraperitoneal organs and part of the pelvic organs. The parietal and visceral layers of the peritoneum are in sliding contact; the potential space between them is called the peritoneal cavity and is a part of the embryologic abdominal cavity or primitive coelomic duct. To understand the complex anatomical construction of the different variants of plicae and recesses of the peritoneum, an appreciation of the embryologic development of the peritoneal cavity is crucial. This knowledge reflects the understanding of the peritoneal anatomy, deep knowledge of which is very important in determining the cause and extent of peritoneal diseases as well as in decision making when choosing the appropriate therapeutic approach, whether surgery, conservative treatment, or interventional radiology.ZusammenfassungDie Bauchhöhle wird in die von Bauchfell (Peritoneum parietale) ausgekleidete Peritonealhöhle und den extraperitonealen Raum unterteilt. Topographisch unterscheidet man den eigentlichen Bauchraum, das Abdomen und die Beckenhöhle. Das Peritoneum überzieht mit einem viszeralen Blatt, Peritoneum viscerale, die intraperitonealen Bauch- und Teile der Beckenorgane. Zwischen Peritoneum parietale und viscerale liegt die als Teil der embryonalen Leibeshöhle entstandene Bauchhöhle. Zum Verständnis des Bauchfellverlaufs müssen die Entwicklungsvorgänge in der Bauchhöhle bekannt sein. Eine profunde Kenntnis dieser unterschiedlichen Räume und deren Begrenzungen ist wichtig, um die Ausbreitung von Infektionen und Neoplasien bzw. die Genese verschiedener Erkrankungen zu verstehen. Sie ermöglich es dem Radiologen, im Zusammenhang mit der klinischen Anamnese und den charakteristischen Bildgebungsmerkmalen die Differenzialdiagnose möglicher Ursachen zu finden und die richtige Diagnose zu stellen – mit entsprechender therapeutischer RelevanzAbstractThe abdominal cavity is subdivided into the peritoneal cavity, lined by the parietal peritoneum, and the extraperitoneal space.

Diseases of the peritoneum and mesenterium

Peritoneal diseases can be seen in the different imaging modalities either as fluid collections or solid tumors along the ligaments, mesenteries, and spaces of the peritoneal cavity. The broad spectrum of different abnormalities includes inflammatory, infectious, traumatic, and neoplastic diseases. In this article, a large variety of peritoneal abnormalities such as ascites, peritonitis, intraperitoneal hemorrhage, and both primary and secondary peritoneal tumors are discussed. The different imaging modalities, characteristic radiological features, and typical pathways of anatomic spread are explained.
