Learning objectives
The purpose of this poster is to describe the imaging features and diagnostic clues of different pathology affecting the inguinal canal.
In addition,
the anatomy of the inguinal canal is reviewed in detail.
Background
The inguinal region is a complex area,
intersecting multiple structures that form a short and narrow passage in the lower abdominal wall,
lined by the aponeuroses of the external oblique,
internal oblique and transversus abdominis muscles.
The structures that cross the inguinal canal are different depending on gender,
so some pathologies are specific and should be suspected,
when in the proper clinical context.
A variety of nonneoplastic and neoplastic masses can be found in the inguinal region,
and the identification of certain characteristic imaging features,...
Findings and procedure details
The initial evaluation of inguinal canal (IC) after physical examination,
usually begins with ultrasound,
since IC is superficial and easy to study by this method.
Ultrasonography allows imaging in real time,
at rest or using dynamic patient maneuvers that can be optimized based on the suspected pathology.
So,
it is essential to know the types of probe to be used (usually high-frequency linear transducers) and the correct positioning of the probe to obtain the appropriate plans,
based on the anatomical points of reference.

Conclusion
Familiarity with normal imaging features of inguinal canal helps the assessment of various inguinal pathology.
A combination of clinical and laboratory findings is crucial in patient assessment,
facilitating improved accuracy in the interpretation of imaging findings and allowing not only precise diagnosis but also the best decision about the treatment.
