Diagnostic Ultrasound - Abdomen and Pelvis

Renal Cell Carcinoma
(Left) Longitudinal US shows
exophytic, heterogeneous
clear cell renal carcinoma st.
There is some posterior
acoustic enhancement from
internal cystic/necrotic
components ſt. (Right) Color
Doppler US in the same
patient with exophytic
heterogeneous renal
carcinoma st shows
prominent internal and
peripheral color flow.
Diagnoses: Urinary Tract
(Left) Longitudinal color
Doppler ultrasound in a
patient with clear cell RCC
shows prominent peripheral
ſt and internal vascularity
within a solid mass. (Right)
Coronal CECT of the same
patient shows a lobulated,
well-defined, enhancing
intrarenal RCC . Note the
hypodense rim st.
(Left) Longitudinal ultrasound
shows a small, hyperechoic,
partly exophytic clear cell RCC
, which may be mistaken for
an angiomyolipoma. These can
be distinguished by confirming
the presence of macroscopic
fat with CT or MR. (Right)
Longitudinal ultrasound in a
patient with angiomyolipoma
shows a small, cortical,
hyperechoic lesion .
Echogenicity was higher than
the preceding RCC. No color
flow was detected. CT or MR
can confirm the diagnosis.
