Lesions Without Borders: Scrotal Lesions That Involve Both the Intratesticular and Extratesticular Regions

OBJECTIVE: Differentiation of scrotal lesions is often dictated by whether they are intraor extratesticular. However, these regions are not entirely isolated, and disease processes can span both spaces. We review a variety of lesions that can involve both regions, describe the relevant anatomy, and illustrate their imaging appearances. CONCLUSION: Identification of involvement of both intra- and extratesticular regions by a single process can narrow the differential considerations and help arrive at the correct diagnosis.
