[Bilateral intrauterine testicular torsion in a newborn]

A case of bilateral perinatal testicular torsion that presented with unilateral torsion; necessity of contralateral testis exploration

Perinatal testicular torsion is a rare emergency in a neonate that prompts immediate attention. Bilateral testicular torsion is extremely rare. We report a case of bilateral torsion that presented with unilateral scrotal swelling but significant atrophy and dark discoloration of the contralateral testis that was secondary to asynchronous prenatal torsion. There is no consensus about exploration of the contralateral testis when exploring a case with unilateral testicular torsion. Nevertheless, findings in this case report indicate that bilateral exploration is mandatory in each case of perinatal testicular torsion to evaluate the condition of contralateral testis and fix it to prevent development of future torsion that may result in anorchia.

Perspectives in Pediatric Pathology, Chapter 19. Testicular Torsion, Testicular Appendix Torsion, and Other Forms of Testicular Infarction

Among the most frequent specimens at the pediatric surgical pathology bench, orchiectomy performed after testicular torsion deserves significant attention. Multiple implications, including fertility, legal complications, possibility of occult lesion, and others, need to be considered. Furthermore, torsion of testicular and other appendices represents common urological emergencies frequently encountered in surgical pathology. Here we present a review of testicular torsion and infarction, including theories about their pathogenesis and the appropriate handling by the diagnostic pathologist.
