Diagnostic Ultrasound - Abdomen and Pelvis

Cystic Renal Mass
Multicystic Dysplastic Kidney
Cystic Renal Cell Carcinoma
(Left) Longitudinal ultrasound
of the kidney in an infant
shows multiple
noncommunicating cysts ſt
with no normal intervening
parenchyma. (Right)
Longitudinal ultrasound of a
failing renal transplant is
shown. A thick-walled cystic
lesion ſt in the lower pole
contains a solid nodule st
with internal color Doppler
flow (not shown). Enhanced
CT confirmed that this was
enhancing and nephrectomy
was performed.
Differential Diagnoses: Kidney
Renal Abscess
von Hippel-Lindau Disease
(Left) Transverse ultrasound of
the left kidney in a patient
with fever, chills and
bacteruria is shown. A cystic
lesion ſt with internal debris
st represents an abscess.
Knowledge of the clinical
picture is essential for
diagnosis. (Right) Longitudinal
ultrasound shows an exophytic
upper pole simple cyst ſt and
a mid pole exophytic renal
carcinoma st with internal
color Doppler flow.
Arteriovenous Fistula/Malformation;
Intrarenal Aneurysm
Arteriovenous Fistula/Malformation;
Intrarenal Aneurysm
(Left) Transverse ultrasound of
a renal transplant shows a
tubular, serpiginous, fluidfilled
structure ſt extending
from sinus to cortex
representing a large, postbiopsy
arteriovenous fistula.
Color Doppler should be used
to evaluate all cystic lesions.
(Right) Transverse Doppler
ultrasound of the same
patient shows high-velocity
turbulent flow ſt in the
arteriovenous fistula st.
