“…It has been reported that SUVmax of 18 F-FDG PET/CT indicates the degree of malignancy in thymic epithelial tumors (5,6), and inflammation such as in abscesses (7). There have been no reports suggesting that the cells present in mediastinal cysts under noninflammatory conditions exhibit glucose uptake.…”

Imaging acquisition and analysis 18 F-FDG PET/CT : Of the 36 patients, 20 underwent 18 F-FDG PET/CT before the surgery. The patients were confirmed to have blood glucose levels !150 mg/dl, and were intravenously injected with 3.7 MBq/kg of 18 F-FDG. One hour after 18 F-FDG injection, the patients were examined using a PET/CT scanner (Aquiduo; Toshiba Medical Systems Corporation, Tochigi, Japan), which was replaced with a new PET/CT scanner (GE Healthcare, Chicago, United States) in April 2015. For examination using the new PET/ CT scanner, patients were intravenously injected with 3.0 MBq/kg of 18 F-FDG. Images from each patient were acquired from the top of the head to the middle of the thigh. CT images were acquired using a 16-slice multi-detector row CT (MDCT) scanner under free breathing conditions, and reconstructed using a slice thickness Table1.

“…In einer anderen Studie zeigten sich ebenfalls höhere SUVmax-Werte bei malignen Thymomen (Schwellenwert 3,4). Zwischen verschiedenen Entitäten zeigten sich allerdings erhebliche Überlappungen der individuellen SUVmax-Werte, sodass im Einzelfall eine eindeutige Zuordnung nicht möglich scheint [23].…”

ZusammenfassungDie Einteilung des Mediastinums erfolgt anhand computertomografischer Aufnahmen in ein ventrales prävaskuläres, mittleres viszerales und dorsales paravertebrales Kompartiment. In den einzelnen Kompartimenten kommen verschiedene Tumorentitäten besonders häufig vor, die entsprechend kurz vorgestellt werden. Im Folgenden werden die typischen bildmorphologischen Zeichen in Röntgen, Sonografie, CT und MRT vorgestellt. Mithilfe der morphologischen Kriterien lassen sich oftmals einzelne Läsionstypen bzw. deren Malignitätsgrad nicht ausreichend abgrenzen. Daher spielen vor allem die funktionellen Informationen im PET und der MRT eine wichtige Rolle zur nicht invasiven Klassifikation. Zur Sicherung einer histologischen Diagnose steht mit den CT-gesteuerten Biopsiemöglichkeiten eine ambulant durchzuführende Option mit hoher diagnostischer Genauigkeit und geringen Komplikationen zur Verfügung.

“…it must be highlighted that also non-malignant conditions, such as teratoma and thymic cysts, have shown to have FdG accumulation in 14% to 42% of cases. [42][43][44] The mediastinum is divided into main three compartments, and this is useful in developing a differential diagnosis when an abnormality is detected: the anterior, middle and posterior compartment. The most common lesions occurring in the anterior mediastinum are represented by thymoma, teratoma/germ cell tumor, lymphoma, and thyroid tissue, whereas in the middle mediastinum is lymphadenopathy, which can be secondary to lymphoma, sarcoid, or metastatic lung cancer.…”

Endobronchial ultrasound (EBUS) has revolutionized the field of bronchoscopy because it allows to observe peribronchial structures and distal peripheral lung lesions. The use of EBUS was first described by Hurte and Hanrath in 1992. EBUS technology exists in two forms: radial and convex transducer probes. The radial EBUS probe has a 20-MHZ (12-30 MHz available) rotating transducer that can be inserted together with or without a guide sheath through the working channel (2.0-2.8 mm) of a standard flexible bronchoscope. The transducer rotates and produces a 360-degree circular image around the central position of the probe. There are two types of radial EBUS probes: "peripheral" probes, used to identify parenchymal lung lesions, and "central" probes, with balloon sheaths, used for the assessment of airway walls and peribronchial lymph nodes.
