Rare primary mature teratoma of the liver: A case report.

Background: Primary liver teratoma is an extremely rare tumor usually affecting children under the age of 3 years. Specific signs of teratoma on ultrasound, computed tomography (CT) or magnetic resonance imaging are lacking, which makes morphology the only diagnostic tool. Misdiagnosis of a mature teratoma may lead to excessive liver resection, whereas misdiagnosis of an immature teratoma may result in spread, causing a life-threatening condition.

Spleen-preserving distal pancreatectomy with resection of the splenic vessels. Should one rely on the short gastric arteries?

Context: Knowing the collaterals is essential for a spleen-preserving distal pancreatectomy with resection of the splenic vessels.

Objective: To ascertain the sources of the blood supply to the spleen after a spleen-preserving distal pancreatectomy with resection of the splenic vessels.

Methods: Perfusion of the cadaveric left gastric and right gastroepiploic arteries with methylene blue after occlusion of all the arteries except the short gastric arteries (n=10).
