Apr 8, 2022 · A wide range of benign and malignant processes can affect the spermatic cord (SC). Familiarity with and recognition of the characteristic imaging features of these entities are imperative for accurate diagnosis and optimal clinical care. While some SC diseases are self-limiting, others can result in infertility and potentially life-threatening infection or bleeding if they are left untreated ... Torsion of the testicular appendage is a common cause of acute scrotal pain and may clinically mimic a testicular torsion . At US, an appendix testis with spherical shape and size larger than 5–6 mm with no internal blood flow and increased peri-appendiceal vascular signals is strongly suggestive of the torsion of appendix testis (Fig. 3 a, b) [ 4 ].Clinical palpability of the lesion and testicular atrophy at the baseline ultrasound study, history of previous testicular cancer, and age were not statistically different between patients with malignant lesions and patients with benign lesions. ... Department of Radiology, Memorial Sloan Kettering Cancer Center, 1275 York Ave, …OBJECTIVE. Heterogeneous or mottled testes in middle-aged or elderly men are often encountered on sonography.

Citation, DOI, disclosures and article data. Cryptorchidism refers to an absence of a testis (or testes) in the scrotal sac. It may refer to an undescended testis, ectopic testis, or an atrophic or absent testis. Correct localization of the testes is essential because surgical management varies on location.

These testes probably do not have to be sonographically followed up unless there is a strong risk factor, such as a previous testicular cancer or a known extratesticular malignancy (prostate, lung), which …

Ultrasound. At sonography, it appears as multiple small cystic or tubular anechoic structures that replace and enlarge the testicular mediastinum. The geographic shape, lack of mass effect, and lack of internal vascularity (Doppler flow) are helpful to distinguish this benign condition from a partially cystic tumour.

Orchitis is defined as the inflammation of the testicle unilaterally or bilaterally usually caused by viruses and bacteria. Testes are two oval male reproductive organs situated in the scrotum. They are responsible for the production of male sex hormones and sperm. The testis is innervated by the testicular plexus, which contains …

Case Discussion. Testicular atrophy is the gradual decrease in size of the testicles, it can be bilateral or unilateral. It is mostly associated with orchitis, hormonal imbalance , torsion and varicocele. Clinical symptoms include infertility, reduced muscle mass and lower sex drive. Erectile dysfunction in testicular atrophy patients occur due ...High-frequency ultrasonography (US) with a linear-array transducer is the modality of choice for the initial evaluation of patients with acute scrotal pain after trauma. Testicular trauma is the third most common cause of acute scrotal pain.

Bilateral impalpable undescended testes with ambiguous genitalia may suggest an endocrine abnormality, such as congenital adrenal hyperplasia. Inspect the scrotum for symmetry, size, and colour.Testicular lymphoma is an uncommon testicular malignancy. Lymphoma can involve the testes in three ways: primary site of extranodal disease ( primary testicular lymphoma) secondary involvement of systemic disease. primary manifestation of subclinical systemic disease. This article is concerned with primary testicular lymphoma.

Testicular torsion is a urological emergency caused by the loss of testicular tissue due to ischemic damage. Rapid diagnosis and urgent treatment play a crucial role in the management of testicular torsion. Manual detorsion can be performed at the bedside, thereby reducing the duration of ischemia.

Testicular biopsy can be performed under local and general anaesthesia. Usually, the procedure is performed as day-care surgery in an outpatient clinic setting. For a diagnostic testicular biopsy, a scrotal incision of 2–3 cm could allow enough exposure of the tunica albuginea of the testis.A varicocele is a varicose vein of the testicle and scrotum that may cause pain, testicular atrophy (shrinkage) or fertility problems. Veins contain one-way valves that work to allow blood to flow from the testicles and scrotum back to the heart. When these valves fail, the blood pools and enlarges the veins around the testicle in the scrotum ...In some cases, testicular atrophy may develop secondary to the parenchymal compression . Fig. 20.

Testicular trauma is a common cause of acute scrotal pain. Blunt trauma is the most common mechanism of injury, and is often due to physical assault, motor vehicle accidents, or athletic injuries. Penetrating scrotal injuries are less common, and are potentially due to stab wounds, projectile injuries or bites.This calculator performs multiple quadratic regressions, each quadratic regression centered at the age of interest, spanning relatively short age range (30 data points). Exceptions are made for youngest and oldest age groups, where it not possible to center the regression. Radiology calculators for normal range percentiles, volume, etc.Over time, more than 20% of patients develop testicular atrophy if left untreated. USG is a valuable diagnostic method in the evaluation of testicular volume in these patients. If the volume difference between the two testes with scrotal USG is 2cc (ml) or more, this is not normal and there is testicular damage. Surgery should be performed …Testicular tumors are more frequent in both the undescended and the contralateral testis. It is estimated that the risk is 6.33 times higher than in the general population for the testicle that has been descended and from 1.74 to 2.90 for the contralateral testicle. The further away from the scrotum the testis is, the greater the risk.Atrophy from a prior ischemic or inflammatory event often has reduced flow.
