Diagnostic Ultrasound - Abdomen and Pelvis

Leiomyoma
(Left) Transverse
transabdominal ultrasound
demonstrates a mixed
echogenicity mass with areas
of internal cystic change ſt,
suggestive of a degenerating
leiomyoma. (Right) Sagittal
T2WI in the same patient
demonstrates a heterogenous
appearance of the large
intramural leiomyoma, with
large areas of increased T2
signal ſt consistent with
cystic degeneration.
Diagnoses: Female Pelvis
(Left) Transabdominal
ultrasound after uterine artery
embolization (UAE)
demonstrates a large region of
increased echogenicity with
poor acoustic penetration and
incomplete "dirty shadowing"
ſt consistent with gas. (Right)
Axial CECT on the same
patient demonstrates
extensive gas ſt throughout
the nonenhancing leiomyoma,
consistent with
postembolization necrosis and
infection, as the patient had
fever and leucocytosis.
(Left) Longitudinal
transvaginal ultrasound
demonstrates an echogenic
circumscribed mass in the
posterior uterus ſt without
shadowing, suggestive of a
fat-containing lesion. Close
attention should be made to
the location of the mass to
avoid confusion with an
ovarian dermoid. (Right) Axial
CECT of the same patient
confirms a low-attenuation,
fat-containing mass in the
posterior aspect of the uterus
ſt, consistent with a
lipoleiomyoma.
