FIG. 7.53 Hemorrhagic Pseudocyst in Pancreatic Body. Chronic
pancreatitis–associated debris-illed pseudocyst; it may be dificult or
impossible to distinguish a hemorrhagic pseudocyst from a debris-illed
nonhemorrhagic pseudocyst.
FIG. 7.54 Splenic Vein Clot With Left-Sided (“Sinistral”) Portal
Hypertension. This can result in isolated gastric varices (green arrow),
which can cause life-threatening gastrointestinal bleeding. The hepatopetal
pathway to bypass the splenic vein clot (purple arrow) includes short
gastric collaterals (orange arrow). Long black arrow indicates direction
of blood low.
