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.

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.
