Learning objectives
To learn about the points and pitfalls that may be encountered during the diagnosis of rare external hernias.
Background
An incarcerated external hernia is one of the most common and important diseases encountered in patients with an acute abdomen.
Since this condition affects the indications for surgery,
an accurate diagnosis is necessary.
In addition to physical findings,
computed tomography (CT) examinations are useful during diagnosis.
However,
diagnosis can often be difficult in cases exhibiting uncommon hernia contents,
locations,
or forms.
Several conditions are rare but should be recognizable by radiologists.
Moreover,
many diseases can exhibit similar CT findings,
and this should be kept in...
Findings and procedure details
1.
Hernia containing the appendix: Amyand’s hernia and de Garengeot hernia
Amyand’s hernia
Amyand’s hernia was first described by Claudius Amyand in 1735.
This condition is defined as an incarcerated hernia containing the appendix,
which may be normal or inflamed.
The incidence of Amyand’s hernia is 0.19%-1.7% of reported hernia cases,
with an inflamed appendix present in 0.07%-0.13%.
[1,
2] Amyand’s hernia is 3 times more frequent in children than in adults.
Ultrasonography (US) and CT examinations are useful for detecting the appendix in the...
Conclusion
We have presented diagnostic points and pitfalls for the diagnosis of rare but clinically important external hernias.
