The normal appendix is a wall layered blind-ending, tubular structure that arises from the variably located caecum. The normal appendix visualized without compression can be best seen within free fluid. The arrow indicates the orifice of the appendix.

Video Captions

Benign neuroendocrine pancreatic neoplasia(pNET). B-mode (video 1) and contrast enhanced ultrasound using low mechanical index technique (video 2) are shown (Hitachi Ascendus).

Take Home Message

Endoscopic ultrasound is the method of choice to diagnose and exclude small pancreatic neoplasia. Due to the high spatial resolution provided by EUS small cystic and necrotic areas are easily identified. Typical endosonographic features of pNETs are hypoechogenicity and necrotic areas in B‑mode and arterial hyperenhancement after injection of ultrasound contrast agents.

Dear colleagues,

 

We cordially invite you to Euroson 2020 taking place in Bergen, the gateway to the fjords and mountains of Norway. Bergen is a historic city
beautifully located along the western coastline with a pulsating harbor surrounded by 7 mountains.
The venue of the congress is Grieghallen, named after Norway’s famous composer Edvard Grieg, who was born and lived in Bergen. The congress is organized by the National Centre for Ultrasound in Gastroenterology and Norwegian Society for Diagnostic Ultrasound (NFUD), and this event will be NFUD’s 44th conference.

Euroson 2020 is arranged in collaboration with the Danish (DUDS) and Swedish (SFMU) ultrasound societies, and SonoScandinavia.

The event web site is up and running and you can Register from January 2020 for this exciting event > http://euroson2020.org/

Video and Figure 1

SPN which occurs in young women in the third decade of life has well-defined borders and variable central areas with cystic degeneration, necrosis, or hemorrhage (Figure 1a). Contrast enhanced EUS reveals  in SPN  hypoenhancement in the the arterial and venous phase (Video 1). In contrast, NETs are hyperenhancing lesions. Elastography shows stiffer tissue compared to the surrounding (Figure 1b). Biopsy and immunohistochemical staining were performed for final diagnosis.

Take Home Message

Neuroendocrine tumor (NET) and solid-pseudopapillary neoplasm (SPN) are two types of pancreatic tumor that were sometimes difficult to differentiate. Biopsy and immunohistochemical analysis obtained  by a histological needle biopsy plays a crucial role in differentiating these two tumor types, E-cadherin, chromogranin A, and β-catenin representing the most useful markers which should be employed for differentiating between NET and SPN.

This was a 45-year old man with severe proteinuria. Color Doppler US of the left renal vein (LRV) in transverse plane shows severe compression between abdominal aorta and superior mesenteric artery and bright-colored jetting flow in the inferior vena cava. Measured peak flow velocity was approximately 3 meters per second which is much higher than normal velocity of 40 to 50 cm/sec.

The esophagus can be examined in the cervical region left to the thyroid. During swallowing the moving air within the esophagus can be identified.

Take Home Message

The feasibility of using swallow contrast-enhanced ultrasound (swallow-CEUS) to examine the function of the upper esophagus and to diagnose Zenker diverticulum has been shown.

The left adrenal gland including the adrenal arterial vessels are shown using endoscopic ultrasound color Doppler imaging [Video].

Take Home Message

Endoscopic real-time ultrasound (US) using high-resolution equipment allows visualization of the left adrenal gland as a routine procedure (99 %). Adrenal arteries can be displayed under good circumstances.

Newborn with arterial hypertension and focal renal or adrenal lesion (B-mode ultrasound, 40 mm). Contrast enhanced ultrasound allowed to solve the differential diagnosis. The complete lesion was non-enhancing (contrast injection of Sonovue™, see video). Adrenal hemorrhage is non-enhancing in contrast to adrenal neoplasia.

[Dietrich CF, Buchhorn R]

Take home messages

Contrast enhanced ultrasound (CEUS) allows diagnosis of adrenal hemorrhage and to exclude neoplasia.
CEUS is safe in newborn, children and adults [(1)].
