Rupture of small cystic pancreatic neuroendocrine tumor with many microtumors

Figure 3 Findings from EUS and CH-EUS. A: The lesion in the pancreatic tail shows a hypoechoic peripheral rim and nodule. Inside the cyst, no echoic fluid or solid structure is detected; B: A new, 7-mm microtumor in the pancreatic body, apparent only on EUS; C: The rim of the cystic lesion and nodule appear enhanced immediately after injection of contrast medium on CH-EUS; D: The 7-mm microtumor is similarly enhanced on CH-EUS; E: Endoscopic ultrasound-fine needle aspiration to biopsy the 7-mm microtumor. CH-EUS: Contrast-enhanced harmonic-endoscopic ultrasound; EUS: Endoscopic ultrasound.
