14Cystic lesion
- simple hepatic cysts (congenital hepatic cysts)
- Traumatic cysts
- parasitic cysts
- inflammatory cysts
- polycystic disease
- pseudo-cysts
15Simple Hepatic Cysts
- Ultrasound findings
- The cyst walls are thin with well-defined
- borders
- anechoic in the cyst
- distal posterior enhancement
- Sometimes cysts contain fine linear
- internal septal.

17Hepatic Abscess
- Ultrasound findings
- Round or ovoid shape with thick wall
- Hypoechoic , complex , may be have a fluid
level - (with some debris along the posterior margin)
- hyperechoic with dirty shasowing (if gas is
present) - posterior enhancement
-
18Cavernous Hemangioma
- ultrasound findings
- round , oval, or lobulated shape with well-
- defined borders
- hyperechoic, anechoic, mixed pattern
- posterior enhancement
