Abstract
Background Multiparametric MRI (mpMRI) of the scrotum has been established as a useful second‐line diagnostic tool for the investigation of scrotal diseases. Recently, recommendations on clinical indications for scrotal MRI were issued by the Scrotal and Penile Imaging Working Group of the European Society of Urogenital Radiology. Objective To update current research on when to ask for an MRI of the scrotum. Methods PubMed database was searched for original articles and reviews published during 2010–2021. Results Eighty‐three articles fulfilled the search criteria. Scrotal MRI is mainly recommended after inconclusive US findings or inconsistent with the clinical examination and should be asked in the following cases: differentiation between intratesticular and paratesticular lesions (in rare cases of uncertain US findings), characterization of paratesticular and intratesticular lesions (when US findings are indeterminate), discrimination between germ cell and sex cord‐stromal testicular tumors, local staging of testicular malignancies (in patients planned for testis‐sparing surgery), differentiation between seminomas and non‐seminomatous tumors (when immediate chemotherapy is planned and orchiectomy is delayed), assessment of acute scrotum and scrotal trauma (rarely needed, in cases of non‐diagnostic US findings) and detection and localization of undescended testes (in cases of inconlusive US findings). Although preliminary data show promising results in the evaluation of male infertility, no established role for mpMRI still exists. Conclusion Multiparametric MRI of the scrotum, by assessing morphologic and functional data represents a valuable problem‐solving tool, helping to improve our understanding on the nature of scrotal pathology and the process of spermatogenesis. The technique may improve patient care and reduce the number of unnecessary surgical procedures.

Abstract
Magnetic resonance imaging (MRI) of the scrotum represents a useful supplemental imaging technique in the characterization of scrotal masses, particularly recommended in cases of nondiagnostic ultrasonographic findings. An accurate characterization of the benign nature of scrotal masses, including both intratesticular and paratesticular ones may improve patient management and decrease the number of unnecessary radical surgical procedures. Alternative treatment strategies, including follow-up, lesion biopsy, tumor enucleation, or organ sparing surgery may be recommended. The aim of this pictorial review is to present how MRI helps in the characterization of sonographically indeterminate scrotal masses and to emphasize the key MRI features of benign scrotal masses.

Abstract
Polyorchidism is defined as the presence of more than two testes. This rare congenital anomaly has been reported with only 140 pathologically proven cases in the published literature to date. While triorchidism is the most common variation and generally affects the left side, bilateral polyorchidism is even rare and only seven cases of patients with four testes have been reported in the literature. There is no consensus in the literature regarding the management of supernumerary testis due to its rareness. We report such a rare case of a 20-year-old male patient, who was presented with left-sided scrotal mass and right inguinal swelling and, diagnosed as polyorchidism including four distinct testes, with two of them in left hemiscrotum and the other two testes in the right inguinal canal. The patient underwent orchiopexy for the normal looking right-sided testis, and orchiectomy for the right-sided supernumerary testis being dysmorphic and potential malignancy risk. Histopathological examination confirmed the excised tissue to be severely atrophic testicle. The patient is still following with regular self-examination and scrotal ultrasonography. Polyorchidism should be keep in mind especially for the differential diagnosis of extratesticular and paratesticular masses. Physical examination may not be sufficient, and radiologic examination can provide accurate diagnosis. Conservative, extirpative or reconstructive approaches could be performed based on individual basis by reproductive potential and location of supernumerary testis, coexistence of other disorders and suspicion of malignancy.

Abstract
Supernumerary testis or polyorchidism is a rare congenital anomaly with about 200 reported cases in the literature. It may be associated with cryptorchidism, testicular torsion and neoplasms. Ultrasonography and magnetic resonance imaging are effective noninvasive methods of accurately detecting polyorchidism. In most cases, ultrasonography is diagnostic and magnetic resonance imaging plays confirmatory role by providing additional information if complicated with neoplasia. We report a case of 16-year-old man with right supernumerary testis associated with adenomatous hyperplasia of the rete testis, its sonographic and magnetic resonance imaging findings and management.

Abstract
Polyorchidism is a rare congenital anomaly, readily diagnosed on ultrasound. Testicular microlithiasis is a condition increasingly recognized and with a possible association with primary testicular malignancy. Rete testis has a variable appearance and is an unusual finding in the young patient. We describe the ultrasound appearances of the combination of polyorchidism, rete testis and microlithiasis, a combination that has not been previously reported.

Abstract
OBJECTIVE To describe the embryologic, clinical, sonographic, and magnetic resonance imaging features of polyorchidism and to review the literature on similar cases. METHODS Over a 5-year period, we encountered 3 patients who were found to have polyorchidism on scrotal sonography. All 3 patients had a painless scrotal mass. Two patients also had magnetic resonance imaging of the scrotum, and the results were correlated with the sonograms. We also performed a literature search for other reports of polyorchidism. RESULTS One patient had 2 right testicles and a single left testicle. The second patient had 3 left testicles and 1 right testicle. In the third patient, who had 2 left testicles and 1 right testicle, microlithiasis was found in all 3 testes. The supernumerary testes were within the scrotum in all cases. All testicles were identified by sonography. Magnetic resonance imaging in 2 cases provided confirmatory data regarding the presence of an extra testicle but did not add other relevant information. Conservative treatment was chosen in all cases. CONCLUSIONS Polyorchidism is a rare congenital anomaly. There are characteristic sonographic features of polyorchidism, and the diagnosis is often made on the basis of sonography. Magnetic resonance imaging can be used for confirmation but may be more helpful in cases complicated by cryptorchism or neoplasia. Conservative treatment is advised in uncomplicated cases.

Abstract
The extratesticular scrotal contents consist of the epididymis, spermatic cord, and fascia derived from the embryologic descent of the testis through the abdominal wall. As opposed to intratesticular masses, most extratesticular masses are benign. Cystic masses (including hydroceles, epididymal cysts, and varicoceles) are easily diagnosed with ultrasonography (US) and are benign. Epididymitis is a common extratesticular lesion as well as the most frequent cause of an acute scrotum. It may be either acute or chronic and can be potentially complicated by epididymo-orchitis or scrotal abscess. Findings include epididymal enlargement, skin thickening, hydroceles, and hyperemia. The epididymis can also be affected by sarcoidosis, a noninfectious granulomatous disorder. The most common extratesticular neoplasms are lipomas (most often arising from the spermatic cord) and adenomatoid tumors (most often found in the epididymis). Despite their relative rarity, malignant neoplasms do occur and include rhabdomyosarcoma, liposarcoma, leiomyosarcoma, malignant fibrous histiocytoma, mesothelioma, and lymphoma. These tumors are often large at the time of presentation. The US findings of solid masses are often nonspecific. Magnetic resonance imaging can be very helpful in the evaluation of some of these disorders, allowing for a more specific diagnosis in cases of lipoma, fibrous pseudotumor, and polyorchidism.
