Diagnostic Ultrasound - Abdomen and Pelvis

Biliary Hamartoma
Diagnoses: Liver
(Left) Grayscale ultrasound of
the liver shows
inhomogeneous liver
parenchymal echotexture due
to multiple biliary
hamartomas that are too
small to resolve. Other small,
cystic lesions ſt represent
slightly larger biliary
hamartomas in which the
internal cystic content can be
resolved. (Right) On a color
Doppler ultrasound, the cystic
space is confirmed to be
avascular ſt in this patient
with numerous biliary
hamartomas.
(Left) Axial CECT in the same
patient shows multiple tiny,
low-density biliary
hamartomas randomly
distributed in the liver
parenchyma . (Right)
Grayscale ultrasound of the
liver shows multiple tiny,
echogenic foci with associated
"comet tail" artifacts ſt in
this patient with multiple
biliary hamartomas.
(Left) Grayscale ultrasound of
liver shows multiple tiny,
echogenic foci with "comet
tail" artifacts from biliary
hamartomas. (Right) Axial T2
FS MR of the liver shows
innumerable high signal
intensity foci ſt consistent
with biliary hamartomas.
