Abstract
Conventional US is the primary imaging modality for the evaluation of the scrotum, due to its high resolution, availability, cost-effectiveness and absence of ionizing radiation. Grayscale and color Doppler US provide a comprehensive assessment of scrotal diseases. The technique represents the mainstay for imaging of acute scrotum. US is highly accurate in the detection, localization and characterization of scrotal masses. Multiparametric US, including conventional US, contrast-enhanced US and tissue elastography has improved the diagnostic performance of the technique in the assessment of testicular diseases. MRI represents a valuable supplemental imaging tool for the investigation of scrotal pathology, mainly recommended in cases of indeterminate US findings. Recommendations recently issued by the European Society of Urogenital Radiology Scrotal and Penile Imaging Working Group (ESUR-SPIWG) refer to the use of scrotal sonography for the evaluation of pathologic entities, including testicular microlithiasis, small, non-palpable incidentally detected testicular masses, varicocele and scrotal trauma. In this review, the technical specifications for scrotal US and the normal sonographic findings are presented. Grayscale and color Doppler US findings of common acute scrotal diseases and scrotal masses are discussed. The complimentary role of multiparametric US and scrotal MRI is addressed. ESUR-SPIWG's guidelines are also reviewed.

Abstract
Background Testicular adrenal rest tumors (TARTs) are benign neoplasms affecting patients with congenital adrenal hyperplasia (CAH). The prevalence of TART in adult patients with CAH is not well known. Ultrasonography (US) is the main tool for diagnosing TART and the role of contrast-enhanced US (CEUS) is never investigated. The aim of this study was to evaluate the TART prevalence in adults with CAH, by stratifying patients according to disease phenotype and assessing the diagnostic performance of US, color Doppler (CD) US and CEUS. Methods Male patients >16 years old with certain diagnosis of CAH who underwent US for TARTs, between December 2015 and September 2019 were prospectively enrolled. The control group included patients without CAH affected by testicular lesions at US other than TARTs. Results TARTs were identified in 16 of 52 patients (31%), of whom 15 (93.8%) displayed the salt-wasting (SW) form (P<0.001). The prevalence of TARTs in patients with the SW form was 54%. One patient with the non-classic (NC) form (6%) showed TART (likely the first documented case). The mean age of patients upon detection of TARTs was significantly younger compared with the control group (P<0.001); moreover, TARTs were bilateral in 15/16 patients (93.8%; P<0.001) and the largest lesion was more frequent in the medium third of testis in the TART group (87.5%), statistically different from the control group (P=0.013). Conclusions TARTs almost exclusively affected patients with the SW form of CAH. Age at diagnosis and bilateralism are useful factors for achieving a correct diagnosis of TARTs in CAH adult patients.

Abstract
PURPOSE Testicular adrenal rests tumor (TART) is a rare kind of benign tumor in the testis. It usually occurred secondary to congenital adrenal hyperplasia (CAH), a hormonal disorder caused by hydroxylase deficiency. As the first-line examination method, ultrasound provides crucial diagnostic information for TART, although misdiagnosis to malignancy is quite common because of its rare prevalence. We aimed to summarize the sonographic manifestations of TART to improve the diagnostic accuracy and specificity. METHODS Eight CAH patients with TART identified by ultrasound in our medical center were retrospectively reviewed. Clinical and hormonal profile, semen analysis and treatment choices were collected. Sonographic examinations were performed at the first evaluation and interpreted by experienced radiologists individually. All patients received regular follow-up, and 5 patients undertook repeated scrotal ultrasound. A literature review of TART in CAH patients was conducted, with 123 patients from 23 articles since 1990 included. RESULTS A total of 8 patients aged between 4 to 27 years old were enrolled. 7 of 8 (87.5%) patients exhibited bilateral testicular lesions. The sizes of the testicular lesions were between 0.18 ml to 5.68 ml, and all showed a clear boundary. 10/15 (66.7%) lesions were homogenously hypoechoic, 4/15 (26.7%) were heterogeneously iso-hypoechoic, and 1/15 (6.7%) were homogenously isoechoic. 10/15 (66.7%) lesions were hyper-vascular. The longitudinal follow-up of 5 patients showed testicular lesions changed in terms of size, echogenicity, and vascularity after steroid treatment. A potential correlation may exist between ACTH levels and tumor size (p = 0.066). From the literature review, 100/123 (81%) patients got bilateral lesions, and 95% of them were located near the mediastinum. 80/103 (78%) lesions exhibited a clear boundary, and predominant lesions (74%) were hypoechogenic. Vascularity was with great diversity. Seventy-nine lesions of 44 patients were followed-up by scrotal ultrasound, among which 29 (37%) remained unchanged, 29(37%) shrank, and 21(27%) disappeared. CONCLUSIONS Key sonographic characteristics of TART are: resembled lesions on both testes, located near the mediastinum, clear boundary, and changed in size or echogenicity after steroid treatment. These features can help radiologists to make an accurate diagnosis of TART.

Abstract
Background Testicular adrenal rest tumours (TARTs) are benign testicular masses that are found in inadequately treated patients with congenital adrenal hyperplasia (CAH). Recognizing this association and identifying characteristic ultrasound features of TARTs is important so as to avoid misdiagnosing them as malignancies, which can lead to unnecessary interventions. Case Report We describe a case of a 9-year-old boy, with a diagnosis of CAH and precocious puberty, who was referred to our department for an ultrasound evaluation of the abdomen and scrotum. On ultrasound, there were well-defined, heterogeneous, predominantly hypoechoic, round-to-oval masses in both testes. Taking into account the presence of CAH and a typical sonographic appearance of bilateral testicular masses, a diagnosis of testicular adrenal rest tumour was made; biopsy was deferred and hormonal treatment was modified. Conclusions Prompt diagnosis of testicular adrenal rest tumours is essential, as it only indicates inadequate hormonal control. Moreover, it can prevent unnecessary biopsies and orchidectomies, and can maintain fertility. TARTs have a typical imaging appearance that every radiologist must be aware of.

Abstract
The aim of this study was to evaluate the imaging features of testicular adrenal rest tumors (TARTs) on baseline ultrasound (BUS).The imaging features of 30 TART lesions pathologically or clinically confirmed in 15 patients who had undergone BUS were evaluated, and the sonographic characteristics of the lesions were analyzed.All 15 cases were bilateral and located near the testicular mediastinum. Approximately 56.7% (17/30) of the TART lesions exhibited homogeneous hypoechogenicity, 36.7% (11/30) of the lesions exhibited heterogeneous hypoechogenicity, and 6.6% (2/30) of the lesions exhibited heterogeneous isoechogenicity. In addition, 76.7% (23/30) of the lesions exhibited a rich blood supply, whereas 23.3% (7/30) of the lesions exhibited a scarce blood supply.The sonographic characteristics of the TARTs were bilateral growth, location adjacent to the testicular mediastinum, hypoechogenicity, and rich blood supply, which may play important roles in early clinical diagnosis.

Abstract
Assessment of the neonatal reproductive tract requires an understanding of embryology, awareness of common clinical presentations, and familiarity with normal newborn variation. This review of the neonatal reproductive tract emphasizes the use of sonography in the evaluation of developmental, acquired, and neoplastic conditions in male and female newborns. Anchored in embryologic origins, the discussion also includes descriptions of findings that may be encountered in prenatal imaging. Comments on clinical correlation are included to guide appropriate triaging of these complex cases. Imaging pearls and pitfalls are incorporated into this review, including the recognized effects of maternal hormones in female infants.

Abstract
OBJECTIVES Several cases of testicular adrenal rest tumours have been reported in men with congenital adrenal hyperplasia (CAH) due to the classical form of 21-hydroxylase deficiency but the prevalence has not been established. The aims of this report were to evaluate the frequency of testicular adrenal rest tissue in this population in a retrospective multicentre study involving eight endocrinology centres, and to determine whether treatment or genetic background had an impact on the occurrence of adrenal rest tissue. MATERIAL AND METHODS Testicular adrenal rest tissue (TART) was sought clinically and with ultrasound examination in forty-five males with CAH due to the classical form of 21-hydroxylase deficiency. When the diagnosis of testicular adrenal rest tumours was sought, good observance of treatment was judged on biological concentrations of 17-hydroxyprogesterone (17OHP), delta4-androstenedione, active renin and testosterone. The results of affected and non-affected subjects were compared. RESULTS TART was detected in none of the 18 subjects aged 1 to 15years but was detected in 14 of the 27 subjects aged more than 15years. Five patients with an abnormal echography result had no clinical signs. Therapeutic control evaluated at diagnosis of TART seemed less effective when diagnosis was made in patients with adrenal rest tissue compared to TART-free subjects. Various genotypes were observed in patients with or without TART. CONCLUSION Due to the high prevalence of TART in classical CAH and the delayed clinical diagnosis, testicular ultrasonography must be performed before puberty and thereafter regularly during adulthood even if the clinical examination is normal.

Abstract
Intratesticular haematoma is not well described in the ultrasound literature and may be mistaken for a primary testicular malignancy if a detailed clinical history and careful ultrasound examination are not performed. We report two cases of intratesticular haematoma (one complicated by the presence of microlithiasis), describe the ultrasound appearances and document the natural history of the haematomas. A clinical history coupled with Doppler ultrasound features is crucial for conservative management.

Abstract
Testicular adrenal rests are encountered in ACTH hypersecretion syndromes, most often in congenital adrenal hyperplasia attributable to a deficit in 21-hydroxylase. They are discovered clinically or on systematic sonography, generally in the young adult. On sonography, they appear as confluent hypoechogenic masses, often bilateral, that have developed in the region of the testicular hilum. At a late stage, they take on a highly suggestive attenuating aspect. In color Doppler, they have a regular vascular architecture. They generally regress or stabilize with replacement glucocorticosteroid treatment. They can sometimes progress, which then poses the problem of the type of lesion. Biopsy or spermatic vein samples are not reliable. MRI contributes very little more than sonography. Diagnosis comes with follow-up or, as a last resort, orchidectomy.

Abstract
Sonography is the preferred imaging method for the evaluation of pediatric scrotal swelling. By identifying the site of origin and whether a mass is solid or cystic, the diagnosis is usually readily made, making ultrasound especially valuable in patient management. Scrotal pathology differs in pediatric patients, especially prior to puberty, making understanding of pediatric conditions essential. This article reviews the common intra- and extratesticular causes of pediatric scrotal swelling and their sonographic appearances.

Abstract
Ultrasound plays an important role and adds essential information in diagnosing benign intrascrotal lesions. Characterization of benign intrascrotal lesions with sonography, in combination with clinical assessment, can lead to nonsurgical management or testicular sparing surgery. We present important sonographic features of benign intrascrotal lesions, including extratesticular lesions: adenomatoid tumors, papillary cystadenomas, spermatoceles, hydroceles, varicoceles, hernias; and intratesticular lesions: tunica albuginea cysts, testicular simple cysts, epidermoid cysts, tubular ectasia of the rete testis, intratesticular varicoceles, adrenal rest tumors, and splenogonadal fusion. The goal of this review is to provide the radiologist with a better understanding of benign lesions that occur in the scrotum.
