Cystic Disease Flashcards
Most common renal cystic disease in children
Multicystic dysplastic kidneys
Simple renal cortical cysts
Most common type of prostatic cyst found in the transitional zone
Degenerative prostatic cysts
Massively enlarged echogenic kidneys, loss of CM differentiation, macroscopic cysts are occasionally noted
ARPKD
The echogenic layer of a duplication cyst
Mucosal
Extrahepatic cystic structure that may contain sludge/stones
Choledochal cysts
Small, hyperechoic pancrease
Cystic fibrosis
Autosomal dominant polycystic kidney disease (ADPKD)
A congenital prostatic cyst that is associated with no spermatozoa and a thick wall
Müllerian duct cyst
Duplication cyst
Other lab tests that could be abnormal with cysts present
LFT’s and WBC’s
Renal enlargement, multiple bilateral cysts, both cortical and medullary
Autosomal dominant PKD
Affects the spleen and appears as a solitary cystic structure with internal echoes
Primary congenital cysts
Young children - renal abnormalities more prominent
Older children - liver abnormalities more prominent - portal hypertension
ARPKD
The 4 types of ARPKD based on age at onset
Perinatal, neonatal, infantile, juvenile
Bilaterally echogenic pyramids with possible calcifications localized to the pyramids
Medullary sponge kidneys
Fusiform congenital prostatic cyst associated with infertility
Ejaculatory duct cysts
Caroli’s disease
