Objective:
The aim of this study was to compare the computed tomography imaging features of a torsed inguinal testis with nontorsed inguinal testes.
Methods:
Computed tomography scans of patients with undescended testes were retrospectively collected (2011-2016). Imaging features of nontorsed undescended testis were compared with a case of an inguinal torsed testis. Observations included location of the undescended testis, size (length × width) and texture of each testis, peritesticular findings, position of testicular vessels, and enhancement patterns.
Results:
Twelve nontorsed inguinal undescended testes were compared with 1 torsed undescended testicle. Torsed testis was larger than nontorsed (44 × 27 mm vs 32.9 ± 6.1 × 22.9 ± 4.9 mm), surrounded by fat stranding and fluid, with heterogeneous texture, enhancement of its outer layers, and an upward kink of its vessels.
Conclusions:
Because torsed undescended testis can mimic a groin abscess and because torsion is a medical emergency, radiologists should be aware of this entity and its distinguishing imaging features. Color Doppler examination can ascertain absence/reduction of blood flow.

Imaging Studies III: Computed Tomography
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Testes: Gross Anatomy
Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...

Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
