Abnormal Neck Lymph Nodes
• Heterogeneous echotexture, calcifications, and cystic areas
• Round Lymph node
• Size is less reliable than shape or architecture
• Lymph nodes measuring > 7mm in short axis are suspicious

Figure 6
FIGURE 6. Split-screen long-axis views of a
fat-containing indirect inguinal hernia during
quiet respiration and Valsalva maneuvers. The
left image shows the hernia during quiet
respiration (arrows). The right image, obtained
during a Valsalva maneuver, shows the hernia
contents being forced distally in a horizontal
direction within the inguinal canal (arrows and
dotted arrows).

Figure 7
FIGURE 7. Left image and diagram showing a
typical shape for direct inguinal hernia, a wide
neck in comparison to the fundus. This hernia
shape correlates with complete reducibility.
Right image and diagram show a typical shape
for a an linea alba hernia, a very narrow neck in
comparison to the fundal width. This hernia
shape correlates with nonreducibility and with
an increased risk of strangulation.

Figure 8
FIGURE 8. A, Long-axis view of a moderate-
sized indirect inguinal hernia obtained in the
supine position during a Valsalva maneuver and
showing it to contain only fat. B, Long-axis
view of the same hernia obtained immediately
after the patient was placed in the upright
position. The hernia appears slightly larger than
it was in the previous image but still contains
only fat. C, Delayed imaging in the upright
position now showing that the hernia also
contains fluid. This proves that the hernia
contains intraperitoneal contents not just
preperitoneal contents.

Figure 9
FIGURE 9. Diagram and images of the main
landmark for evaluating the inguinal area, the
inferior epigastric vessels (EIVs). Image 1 is
obtained in a transverse plane about half-way
between the umbilicus and the pubic
symphysis. The inferior epigastric artery and its
paired veins lie along the midlateral posterior
surface of the rectus abdominis muscle. Image
2 is obtained several centimeters inferiorly, and
the EIVs lie more laterally. Image 3 is obtained
at a level where the IEVs (arrow) lie at the
edge of the rectus muscle. (This is the level at
which most spigelian hernias occur.) Image 4
shows that once the origin of the inferior
epigastric artery, the transducer should be
rotated into planes that are parallel and
perpendicular to the inguinal canal-long-axis
and short-axis views.

Figure 10
FIGURE 10. Abdominal and pelvic CT image,
reformatted in the coronal plane, illustrating
the locations of the 4 types of "groin" hernias.
Indirect inguinal hernias arise within the
internal or deep inguinal ring, which lies in the
crotch between the external iliac artery and the
proximal inferior epigastric artery. Direct
inguinal hernias arise through the "conjoined
tendon," which lies inferior and medial to the
origin of the inferior epigastric artery.
Spigelian hernias arise through the spigelian
fascia just lateral to the inferior epigastric
artery where it reaches the lateral margin of the
rectus muscle. Femoral hernias lie within the
femoral canal, inferior to the inguinal canal and
inguinal ligament.
