Post-traumatic dislocation of the testis into the inguinal canal: a rare case report

Abstract Background Traumatic dislocation of the testis (TDT) represents an uncommon yet clinically important outcome following blunt trauma to the scrotum or perineum after straddle or motorcycle-related. Prompt identification is warranted, as delayed detection can result in testicular ischemia, subsequent atrophy, impaired fertility, or persistent orchialgia. Case presentation A 27-year-old male sustained a straddle injury in a motorcycle accident and presented with pain and swelling in the groin. On imaging, it reveals the left testis in the inguinal canal with preserved vascularity, inflamed epididymis, thickened spermatic cord, mild hematocele, and hematoma formation, without evidence of torsion or rupture, and diagnosis of left testicular dislocation was made. Conclusions Traumatic testicular dislocation, though uncommon, should be considered in high-velocity perineal injuries when the testis is non-palpable. Imaging modalities, particularly Doppler ultrasonography and adjunctive CT, facilitate timely diagnosis, while surgical reduction and orchidopexy aid anatomical restoration and function preservation.
