HELPING THE UROLOGIST S261 Imaging of Groin Masses: Inguinal Anat- omy and Pathologic Conditions Revisited 1 Clair L. Shadbolt, MB,ChB ● Stefan B. J. Heinze, MB,BS ● Rosalind B. Dietrich, MB,ChB The groin region is subdivided into two distinct anatomic areas: the inguinal canal and the femoral triangle. A series of cross-sectional im- aging cases illustrate that a good understanding of the local anatomic characteristics of the groin allows confident characterization of groin pathologic conditions. Such conditions can be classified into five major groups: congenital abnormalities, noncongenital hernias, vascular con- ditions, infectious or inflammatory processes, and neoplasms. Con- genital entities include hernias, cysts, undescended testis, and retractile testes. Ultrasound (US) is useful in depicting these conditions. In the second group, noncongenital hernias, US allows visualization of bowel loops in peristalsis within the hernia. Herniography, computed tomog- raphy (CT), and magnetic resonance (MR) imaging are also helpful in diagnosis. Among vascular conditions, false aneurysms may be de- tected from the turbulent flow through the tract at Doppler US. The characteristic venou...
