BIOL 171 Lecture Notes - Lecture 32: Polycystic Kidney Disease, Portal Hypertension, Nephronophthisis
Document Summary
Simple renal cyst: no active immediate action taking on simple cysts. Evaluation of a renal mass: renal masses categorized with sonography as cystic, solid or complex, cystic mass, smooth, thin, well-defined border, round or oval shaped, sharp interface between the cyst and renal parenchyma, no internal echoes (anechoic) Irregular borders: poorly defined interface between the mass and kidney. Low-level internal echoes: weak posterior border (because of the increased attenuation of the mass, poor through-transmission, complex mass shows characteristics associated with both cystic and solid lesions, areas of necrosis, hemorrhage, abscess, or calcification within the mass. Medullary cystic disease: congenital disease, congenital hepatic fibrosis, cysts - variants, msk is associated with a variety of disorders, beckwith-wiedemann syndrome, polycystic kidney disease, caroli disease, congenital hepatic fibrosis, medullary cystic disease (nephronophthisis) Juvenile arpkd: portal veins - have echogenic walls, teenager juvenile. Signs and findings with juvenile arpkd: hypertension, renal insufficiency, nephromegaly, hepatic cysts, bile duct proliferation, caroli disease of the liver, periportal fibrosis.
