Abstract
'-Celes' is an ancient Greek language suffix that means 'tumor,' 'hernia,' 'swelling,' or 'cavity.' There are many '-celes' in the abdomen and pelvis that may be encountered during routine imaging interpretation, including santorinicele, choledochocele, ureterocele, lymphocele, mucocele, rectocele, cystocele, peritoneocele, varicocele, spermatocele, hydrocele, hematocele, pyocele and syringocele. Most '-celes' are detected incidentally at imaging for other clinical indications, but some deserve more attention due to a range of clinical symptoms or functional disorder that can adversely affect patient quality of life. The objective of this article was to address all of the '-celes' that a general radiologist and abdominal radiologist should know and be able to recognize. Imaging characteristics, diagnostic clues, and pitfalls have been provided to improve diagnostic accuracy and patient outcomes.

Abstract
The scrotum may be affected by a plethora of different disorders such as infections, vasculopathies, trauma, and manifestations of primary and secondary malignant masses. In addition to the patient's medical history and clinical examination, ultrasound represents the imaging modality of choice to assess scrotal disorders. Time-consuming contrast-enhanced ultrasound and elastography can provide further information to distinguish between benign and malignant testicular mass lesions. The following invited Special Communication gives a comprehensive overview of differential diagnoses of the scrotum and their corresponding sonomorphologic correlates based on representative cases of the Interdisciplinary Ultrasound Center of the University Hospital Munich.

Abstract
Ultrasonography is the ideal noninvasive imaging modality for evaluation of scrotal abnormalities. It is capable of differentiating the most important etiologies of acute scrotal pain and swelling, including epididymitis and testicular torsion, and is the imaging modality of choice in acute scrotal trauma. In patients presenting with palpable abnormality or scrotal swelling, ultrasonography can detect, locate, and characterize both intratesticular and extratesticular masses and other abnormalities. A 12-17 MHz high frequency linear array transducer provides excellent anatomic detail of the testicles and surrounding structures. In addition, vascular perfusion can be easily assessed using color and spectral Doppler analysis. In most cases of scrotal disease, the combination of clinical history, physical examination, and information obtained with ultrasonography is sufficient for diagnostic decision-making. This review covers the normal scrotal anatomy as well as various testicular and scrotal lesions.

Abstract
Ultrasonography(US) of the scrotum has been demonstrated to be useful in the diagnosis of fluid in the scrotal sac. Grayscale US characterizes the lesions as testicular or extratesticular and, with color Doppler, power Doppler and pulse Doppler, any perfusion can also be assessed. Cystic or encapsulated fluid collections are relatively common benign lesions that usually present as palpable testicular lumps. Most cysts arise in the epidydimis, but all anatomical structures of the scrotum can be the site of their origin. US may suggest a specific diagnosis for a wide variety of intrascrotal cystic and fluid lesions and appropriately guide therapeutic options. The paper reviews the current knowledge of ultrasound in conditions with fluid in the testis and scrotum. The review presents the applications of ultrasonography in the diagnosis of hydrocele, testicular cysts, epididymal cysts, spermatoceles, tubular ectasia, hernia and hematoceles. The aim of this paper is to provide a pictorial review of the common and uncommon presentation of fluid within the scrotal spaces.

Abstract
Sonography is the ideal modality for evaluation and characterization of a scrotal mass. Extratesticular masses are usually benign, whereas intratesticular masses are generally malignant until proved otherwise. However, it is important to recognize the benign intratesticular conditions, thus possibly preventing orchiectomy when unwarranted, while appreciating the more significant findings of extratesticular masses that may warrant further intervention. This article reviews the anatomy and sonographic findings of scrotal masses. Normal anatomy, general imaging techniques, and assessment of intratesticular and extratesticular disorders will be discussed.

Abstract
The widespread use of scrotal ultrasonography (US) has led to increased detection of testicular and extratesticular pathologies. Cystic or encapsulated fluid collections are relatively common benign lesions that usually present as palpable testicular lumps. Most cysts arise in the epidydimis, but all anatomical structures of the scrotum can be the site of their origin. US may suggest a specific diagnosis for a wide variety of intrascrotal cystic and fluid lesions and appropriately guide therapeutic options. US should be used as an adjunctive diagnostic modality after clinical evaluation of a scrotal lesion associated or not with the presence of a lump.

The role of ultrasonography in the differentiation of the various types of filaricele due to bancroftian filariasis. Acta Trop 2011; 120 Suppl 1:S23-32.

Abstract
OBJECTIVE (i) To determine the frequencies of urogenital pathologies in men infected with bancroftian filariasis, and (ii) to evaluate the role of ultrasonography (USG) as a diagnostic tool to differentiate between diverse pathologies with different clinical implications. To date, all types of scrotal enlargement resulting from lymphatic filariasis (LF) have been summarized under one term: "filaricele". PATIENTS AND METHODS Data were compiled from recruitment phases for field trials in an endemic area for LF in Ghana. 1453 men aged 18 years and above underwent ultrasound examinations of the scrotum. Observation parameters were: Filaria Dance Sign (FDS), dilation of supratesticular lymphatic vessels, thickness of scrotal skin, occurrence and amount of fluid accumulation, echogenicity of the fluid between the layers of the tunica vaginalis, as well as position and homogenicity of testis, epididymis and spermatic cord. In 1132 men, blood samples were taken for parasitological analysis. RESULTS In 56% of examined patients, fluid accumulation around the testis was detected (38% subclinical-, 18% clinical stages). Differentiation of the echogenicity of the fluid revealed echo-free hydrocele (EFH) in 47% and echo-dense hydrocele (EDH) in 9%. Patients without hydrocele and subclinical stages had a thinner scrotal skin than those in clinical stages or with lymphscrotum (P < 0.001). In the EDH group the scrotal skin was thicker than in the EFH group (P < 0.001). 1.4% had a lymphscrotum. FDS was detected in 24% of all 1453 volunteers who underwent USG. The number of worm nests correlated with microfilarial load and levels of circulating filarial antigen (P < 0.001; 20% microfilaremic, 48% antigen positive). CONCLUSION In an unexpected high number of men (56%) fluid accumulation around the testis was detected by USG of which more than one third (38%) presented with subclinical stages. The study showed that echo-dense and echo-free fluid could be differentiated and that a considerable number of cases had EDH (9%) posing a risk to develop necrotic testis and infertility and therefore requiring immediate surgical intervention. USG thus turned out to be a useful diagnostic technique to differentiate between those cases requiring immediate surgical intervention from those that can be treated with (anti-wolbachial and hyperpermeability reducing) drugs that ameliorate or halt progression of the disease.

Abstract
Extratesticular lesions are common incidental findings at ultrasonography (US) among men and boys. Most lesions originate from or depend on the tunica vaginalis, a mesothelium-lined sac with a visceral layer and a parietal layer. The tunica vaginalis is formed when the superior portion of the processus vaginalis closes during embryologic development. Abnormal closure of the processus vaginalis leads to congenital anomalies of the tunica vaginalis, such as complete or partial patency of the processus vaginalis, spermatic cord hydrocele, and inguinoscrotal hernia. The proximity of the visceral layer to the testis explains the reactive involvement seen in epididymo-orchitis, with resultant pyocele or abscess formation. The tunica vaginalis also may be affected by inflammatory and traumatic disorders such as scrotal calculi, fibrous pseudotumor, or hematocele. These lesions manifest as solid or heterogeneous tumorlike masses. Lesions of mesothelial origin, such as adenomatoid tumor, tunica cyst, and mesothelioma, may involve the tunica vaginalis. Entrapped mesenchymal cells can lead to lipoma, leiomyoma, or sarcoma, although these tumors are uncommon in the tunica vaginalis. US is not useful for differentiating between benign and malignant tumors; however, some characteristic findings may help in planning the best surgical approach. Knowledge of the embryologic development, anatomic relationships, and pathologic disorders of the tunica vaginalis is essential to narrow the differential diagnosis of an extratesticular lesion. In most cases, US findings in combination with clinical assessment can indicate whether nonsurgical management or testis-sparing surgery is warranted.

Abstract
Ultrasound is a vital adjunct to clinical examination in diagnosing scrotal disease, as a number of different processes may present similarly. Potential applications range from the acute emergency to long-term screening as well as cases in which a distinct scrotal abnormality may or may not be palpable. Differentiating acute epididymitis/epididymoorchitis from testicular torsion is possible sonographically, thereby guiding appropriate medical or surgical management. Distinguishing between cystic, solid, or complex scrotal masses is readily performed with this modality. It clearly depicts simple versus complex hydroceles and determines the presence of underlying testicular or epididymal disease. Not only is ultrasound the best imaging modality for longitudinal screening in patients (testicular microlithiasis, cryptorchidism) at risk for testicular tumors, it also provides valuable information in the infertile male by documenting the presence or absence of a varicocele.

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 is the preferred technique when imaging the scrotal contents. Although appearances of many of the more common abnormalities present the examiner with no diagnostic difficulty, the more unusual conditions may present a considerable challenge. Many normal variants, unusual and rare abnormalities may be instantly recognized once seen. The current review highlights the more unusual and rare conditions affecting the scrotal contents in order to allow the reader the opportunity to gain knowledge of their existence and to aid future interpretation of the difficult examination.

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.

Abstract
Ultrasonography (US) is well suited to the study of pathologic conditions of the scrotum in children. US provides excellent anatomic detail; when color Doppler and power Doppler imaging are added, testicular perfusion can be assessed. Gray-scale, color Doppler, and power Doppler US were used to study a spectrum of scrotal disorders in 750 boys aged 1 day to 17 years. The entities studied included processus vaginalis-related disorders (cryptorchidism, inguinal-scrotal hernia, and hydrocele); varicocele; acute scrotum (epididymo-orchitis, torsion of the testicular appendages, and testicular torsion); scrotal tumors; testicular microlithiasis; scrotal trauma; and systemic diseases with scrotal involvement. When combined with the results of clinical and physical examination, the information obtained with US is sufficient to enable diagnosis in most cases of scrotal disease. Moreover, color Doppler imaging is essential for differentiation between processes such as epididymo-orchitis or torsion of the testicular appendages and testicular torsion, which have similar clinical manifestations (pain, swelling, and redness) but are managed differently.

Abstract
PURPOSE We summarize important clinical, pathological and diagnostic features of benign intrascrotal lesions, including paratesticular lesions (adenomatoid tumors, fibrous pseudotumors, cystadenomas, spermatoceles, hydroceles, varicoceles and hernias) and intratesticular lesions (tunica albuginea cysts, testicular simple cysts, epidermoid cysts, cystic ectasia of the rete testis, intratesticular varicocele, adrenal rest tumors and splenogonadal fusion). This review provides the reader with a better understanding of benign lesions that occur in the scrotum. MATERIALS AND METHODS A directed MEDLINE literature review of benign scrotal lesions and of each individual lesion was performed. This information was enhanced with relevant information from select journals and texts. Particular emphasis was placed on clinical, pathological and diagnostic features. RESULTS Intrascrotal lesions continue to provide a diagnostic challenge for physicians. A diagnosis can be made with a thorough history, physical examination and understanding of the pathophysiological processes of the structures contained within the scrotum. Lesions that are suspicious for malignancy should prompt urological consultation and radiological imaging. Ultrasound aids in the diagnosis in instances of uncertainty. Ultimately surgery may be necessary to make a histological diagnosis. CONCLUSIONS Clinical assessment, physical examination and an understanding of benign intrascrotal processes are key to making a diagnosis. Ultrasound has an important role and adds essential information. If surgery is necessary and a benign process is recognized, a testis sparing procedure should be performed.

Abstract
Ultrasonography (US) with a high-frequency (7.5-10-MHz) transducer has become the imaging modality of choice for examination of the scrotum. US examination can provide information valuable for the differential diagnosis of a variety of disease processes involving the scrotum that have similar clinical manifestations (eg, pain, swelling, or presence of mass). The pathologic condition that may be at the origin of such symptoms can vary from testicular torsion to infection to malignancy. The ability of color and power Doppler US to demonstrate testicular perfusion aids in reaching a specific diagnosis in patients with acute scrotal pain. This review covers the anatomy of the scrotum and the scanning protocol for scrotal US, as well as detailed descriptions of disease processes and their US appearances. Newly described conditions such as intratesticular varicoceles and other benign intratesticular cystic lesions are also discussed.
