Diagnostic Ultrasound - Abdomen and Pelvis

Biliary Hamartoma
(Left) Ultrasound of the liver
shows numerous tiny
echogenic foci ſt and several
cystic lesions st,
corresponding to biliary
hamartomas. Parenchymal
echotexture is heterogeneous
due to biliary hamartomas.
(Right) Ultrasound shows
heterogeneous liver
echotexture due to multiple
biliary hamartomas st that
are too small to resolve. Other
slightly larger cystic lesions
with posterior enhancement
ſt represent biliary
hamartomas in which the
internal content can be
resolved.
Diagnoses: Liver
(Left) Ultrasound shows
heterogeneous liver
parenchymal echotexture due
to multiple biliary
hamartomas that are too
small to resolve. A small,
cystic, slightly larger biliary
hamartoma ſt is seen in
which the internal cystic
content is resolved. (Right)
Ultrasound of the liver shows
coarse parenchymal
echotexture with multiple tiny
echogenic foci ſt throughout
the liver due to the presence
of multiple small biliary
hamartomas.
(Left) Arterial phase of
contrast-enhanced CT shows
multiple tiny cystic lesions in
the liver ſt, which represent
biliary hamartomas. (Right) In
the venous phase of a
contrast-enhanced T1-
weighted MR in the same
patient, the same tiny biliary
hamartomas ſt are seen to a
slightly better advantage as
nonenhancing, tiny rounded
foci throughout the liver.
