Diagnostic Ultrasound - Abdomen and Pelvis

Hepatic Cavernous Hemangioma
(Left) Transverse US of the
liver shows a high-flow
hemangioma st with a large
draining portal vein ſt. In the
setting of ascites and
underlying cirrhosis, diagnosis
of high-flow hemangioma is
challenging by ultrasound
alone. (Right) Contrastenhanced
CT in the same
patient during late arterial
phase shows the high-flow
hemangioma st follows the
blood pool. This lesion
followed the blood pool on
portal venous and delayed
phase images as well as a
draining portal vein (not
shown).
Diagnoses: Liver
(Left) Longitudinal grayscale
US of the liver shows a
hypoechoic hemangioma st in
the setting of a fatty liver. In
this case, the diagnosis of a
hemangioma was confirmed
with cross-sectional imaging
with contrast (not shown).
(Right) Axial T2-weighted MR
of the liver shows a welldefined,
lobulated,
hyperintense hemangioma st
with a markedly hyperintense
central scar ſt.
(Left) Axial T1-weighted
contrast-enhanced MR in the
same patient during the portal
venous phase shows
peripheral nodular
discontiguous enhancement
ſt of the hemangioma that
follows the blood pool. (Right)
Axial T1-weighted contrastenhanced
MR with fat
saturation shows the same
lesion fills-in st in a
centripetal fashion with
enhancement similar to blood
pool.
