Chapter 2
Video 1
Normal aspect of the terminal ileum, appreciable from the ileocecal valve, for up to 10
cm. Terminal ileum is clearly visible above the ileopsoas muscle and iliac vessels. Note
the normal thickening and stratification of the bowel wall, and the absence of plicae.
Chapter 4
Video 1
Ultrasonographic aspect of reactive mesenteric lymph nodes in a 45 years old patient
with immunoproliferative small intestinal disease (IPSID).
Video 2
Ultrasonographic aspect of reactive mesenteric lymph nodes in a 18-year old patient with
celiac disease.
Video 3
B-mode ultrasound (left side) and e.v. contrast enhanced ultrasound (right side) of a large
lymph node in a patient with B-cell lymphoma. Contrast-enhanced ultrasound shows
aberrant vessels and avascular foci that are absent in benign lymph nodes.
Chapter 7
Video 1
Scan of periumbilical region during cough shows the herniation of bowel into para
umbilical hernia.
Video 2
Scan of umbilical hernia, present at rest and being reduced by compression.
Video 3
Transverse scan of epigastrium below the pancreas shows the whirlpool sign in gray scale
and color Doppler as the transducer is moved down.
Video 4
Oblique scan below and to right of the umbilicus shows the whirlpool sign in gray scale
above a mesenteric cyst with segmental volvulus.
Video 5
Color doppler study showing the whirlpool sign in the same patient as Video 4.
Video 6
Oblique scan in right iliac fossa showing the transient Intussusception and its
disappearance after some time.
Video 7
Real time scan, showing the progress and compete reduction of a ileocolic
Intussusception
Chapter 9
Video 1
Epiploic appendagitis (EA) detected in left iliac fossa as a homogeneous hyperchoic mass
with thin hypoechoic border near the sigmoid colon (S).
Chapter 11
Video 1
Transverse scan of the ileum in a Crohn’s disease patient showing thickened bowel walls
just above the bladder, surrounded by mesenteric hypertrophy.
Video 2
Longitudinal scan of the ileum in a Crohn’s disease patient showing thickened bowel
walls with an entero-mesenteric fistula (asterisk) and a chronic stricture characterized by
large pre-stenotic dilatation with weak peristalsis and liquid and semisolid content.
Video 3
Ultrasonographic appearance of entero-enteric fistulae in Crohn’s disease. The fistulae
are detected at ultrasound as hypoechoic ducts among the intestinal loops
Chapter 15
Video 1
Ultrasonographic features of the bowel wall in Henoch-Shoenlein purpura. Longitudinal
scan of the bowel in a 10-year old male patient showing a slight thickening of the bowel
wall, with an extra-echoic layer, internal to the submucosa.
Chapter 16
Video 1
Infectious ileocecitis due to Yersina enterocolitica in a 21-year old male patient.
Ultrasonographic scan showing wall thickening of the terminal ileum with hypoechoic
echopattern and an adjacent mesenteric mass.
Chapter 19
Video 1
Ultrasonographic scan of right iliac fossa showing a thick walled fluid distended
appendix with motile worms in the lumen.
Chapter 20
Video 1
Sonographic features of the carcinoma of the ascending colon that appears, in a
longitudinal scan, as a segmental thickening with abrupt loss of stratification of the
posterior bowel wall (arrows).
Video 2
Rectal cancer. Transversal sonographic scan showing an increased and irregular
circumferential thickening of the rectal walls, with hypoechoic echopattern.
Chapter 24
Video 1
Sonographic features of intestinal endometriosis in a patient with ileo-pouch-analanastomosis for ulcerative colitis. The lesion appears at transabdominal ultrasound as a
hypoechoic nodule with irregular contours involving the deep layers of the bowel wall
and deforming the intestinal lumen, which is easily detectable for its gaseous content.
Chapter 32
Video 1
Trans-sphincteric fistula detected by a longitudinal transperineal scan. The fistula appears
as hypoechoic tract arising from the posterior side of the anorectal junction and crossing
the external anal sphincter.
Video 2
Complex perianal Crohn’s disease characterised by a large perianal abscess extending
(asterisks) beyond the elevator anii.
