A 16-year-old male presented with a painless right testicular mass, known for the past 2 years and that had recently increased in size. Physical examination confirmed a hard testicular mass and no evidence of lymphadenopathy or of gynecomastia. Laboratory results, including tumor markers, were normal. Ultrasound (US) revealed a solid mass in the upper pole of the right testis that was well circumscribed, avascular, and displayed the onionskin appearance suggestive of testicular epidermoid cyst (1,2) ( Figure-1).Magnetic resonance (MR) confirmed the well-circumscribed intra-testicular mass with a A B

High-frequency ultrasonography is the first modality of choice for the evaluation of scrotal pathology. The use of high-frequency ultrasound is increasing, allowing detection and better characterization of many benign intrascrotal lesions that can be treated with non-surgical management or testicular-sparing surgery.This pictorial essay presents gray-scale and color-flow Doppler features of non-neoplastic intratesticular masses. For ease of understanding, the review is organized into three major categories: cystic, vascular, and solid non-neoplastic masses. Table summarizes the key sonographic features, each with recommended management. Sonographic anatomy of the testisThe normal adult testes in each hemi scrotum are symmetric in size and measure approximately 5x3x2 cm. On ultrasound, a normal testis is identified by the presence of homogeneous, medium-level echoes and is contained by a fibrous sheath called the tunica albuginea. The tunica albuginea is identified on ultrasound as a thin echogenic line around the testis and is externally covered by the tunica vaginalis. The tunica vaginalis consists of visceral and parietal layers that are normally separated by a few milliliters (2-3 mL) of fluid. The tunica attaches to the scrotal wall at the posterolateral aspect of the testis. From the posterior aspect of the testis, the tunica albuginea invaginates within the testis to form an incomplete septum, called the mediastinum testis. Sonographically, the mediastinum testis appears as an echogenic band of variable thickness that extends across the testis in the longitudinal axis (Fig. 1). Multiple fibrous septa extend from the mediastinum into the testis, dividing it into 250 to 400 lobules. Spermatogenesis occurs within the seminiferous tubules contained within these lobules. The seminiferous tubules open into dilated spaces called the rete testis within the mediastinum via the tubuli recti. The normal rete testis can be seen on high-frequency US in 18% of patients. (1). The rete testis drains into the epididymis via 10 to 15 efferent ductules.There are four testicular appendages (remnants of the mesonephric and paramesonephric ducts): the appendix testis (hydatid of Morgagni), the appendix epididymis, the vas aberrans, and the paradidymis. The appendix testis and the appendix epididymis are commonly seen on scrotal US. The appendix testis is a small ovoid structure usually at the upper pole of the testis in the groove between the testis and the epididymis, better seen by the presence of fluid around the testis.The testes are supplied by testicular arteries that arise from the abdominal aorta. The testicular arteries enter the spermatic cord at the deep inguinal ring and continue along the posterior surface of the testis, penetrating the tunica albuginea and forming the capsular arteries that course through the tunica vasculosa, which underlies the tunica ABDOMINAL IMAGING PICTORIAL ESSAY Imaging of non-neoplastic intratesticular massesShweta Bhatt, Syed Zafar H.

Intra-testicular epidermoid cyst: a rare case report with clinico-radiological dilemma

et al. 2017

View full text Add to dashboard Cite

Intra-testicular epidermoid cyst of testis is a benign tumour and accounts for 1-2% of all testicular neoplasms. It is a benign lesion, and should be distinguished from dermoid cyst or teratoma, which have a considerable malignant potential. We describe a rare case of testicular epidermoid cyst in an elderly male presenting with gradually increasing testicular mass since 8 months. Local examination revealed a non-tender, irregular, hard mass in the right testis. All routine laboratory investigations along with tumour markers were within normal limits. Ultrasound showed features of a testicular neoplasm following which orchidectomy was performed. Grossly, cut surface of testis showed a cyst measuring 4x2x1cm and microscopic examination revealed features of an epidermoid cyst. Extesive sampling excluded the possibility of a teratomatous focus. This case is described owing to the rarity of this neoplasm and the unusual clinico-radiological presentation. The pre-operative diagnosis of this tumour can be made if characteristic sonographic and MRI findings are obtained in the absence of which these masquerade neoplastic lesions. Histopathological examination thus is vital for a decisive diagnosis.
