Multiparametric ultrasound for the assessment of testicular lesions with negative tumoral markers.

Asian J Androl 2022 Jun 10. Epub 2022 Jun 10.

Department of Ultrasound, Zhongshan Hospital, Fudan University, Institute of Ultrasound in Medicine and Engineering, Shanghai 200032, China.

The purpose of this study was to evaluate the diagnostic performance of multiparametric ultrasound (mpUS; grayscale US, color Doppler US, strain elastography, and contrast-enhanced US) in the assessment of testicular lesions with negative tumoral markers. MpUS imaging data, patient age, serum tumor markers, scrotal pain, cryptorchidism, and related clinical information were retrospectively collected for patients who underwent mpUS examination between January 2013 and December 2019. Histologic results or follow-up examinations were used as the reference standard. Read More

Predicting malignancy in small testicular lesions.

Cent European J Urol 2022 22;75(1):47-51. Epub 2022 Feb 22.

Department of Urology, Pontificate Catholic University, Santiago, Chile.

Introduction: Small testicular lesions ≤20 mm (STL) detected by ultrasound (US), usually non-palpable, have been reported to be benign in up to 80% of cases. Thus, partial orchiectomy with or without frozen section examination and surveillance has been advocated for these kinds of lesions. We seek to report the proportion of benign lesions in testicular tumors ≤20 mm detected by US in our population and explore the predicting factors of malignancy. Read More

ACR Appropriateness Criteria® Staging and Surveillance of Testicular Cancer: 2021 Update.

J Am Coll Radiol 2022 05;19(5S):S194-S207

Specialty Chair, University of Alabama at Birmingham, Birmingham, Alabama; Chair, ACR Appropriateness Committee.

The staging and surveillance of testicular cancer is a complex topic, which integrates clinical, biochemical, and imaging components. The use of imaging for staging and surveillance of testicular cancer is individually tailored to each patient by considering tumor histology and prognosis. This document discusses the rationale for use of imaging by imaging modality during the initial staging of testicular seminoma and nonseminoma tumors and during the planned surveillance of stage IA and IB testicular cancer by histological subtype integrating clinical suspicion for disease recurrence in surveillance protocols.

Metastatic Potential of Small Testicular Germ Cell Tumors: Implications for Surveillance of Small Testicular Masses.

Eur Urol Open Sci 2022 Jun 26;40:16-18. Epub 2022 Apr 26.

Department of Medical Oncology, Cantonal Hospital St. Gallen, St. Gallen, Switzerland.

Incidental detection of urogenital tumors has increased in recent decades owing to the greater use of ultrasonography and cross-sectional imaging. For patients with low-risk prostate cancer or small renal masses, active surveillance represents a valid treatment option. Similarly, for men with small testicular masses <10 mm, active surveillance has been discussed as an alternative to surgery, although little is known regarding the behavior of small testicular germ cell tumors (GCTs).

Elevated HCG and retroperitoneal adenopathy after clomiphene therapy for infertility.

BMJ Case Rep 2022 Apr 26;15(4). Epub 2022 Apr 26.

Division of Urology, University Health Network, Toronto, Ontario, Canada.

In the context of an elevated human chorionic gonadotropin (HCG) with enlarged retroperitoneal nodes and absent testicular tumours, clinicians will consider a diagnosis of extragonadal germ cell tumours. We report the case of a man in his thirties who while on treatment for subfertility with clomiphene citrate was noted to have enlarged retroperitoneal nodes and elevated HCG levels of 75 IU/L. Chemotherapy with bleomycin, etoposide and cisplatin originally planned was deferred when two separate retroperitoneal nodal biopsies returned as benign fibroadipose tissue and HCG levels spontaneously down-trended to 4 IU/L within 4 months of clomiphene citrate discontinuation.

Department of Urology, Medical School of Nanjing University Affiliated Jinling Hospital, Nanjing 210002, China.

Von Hippel-Lindau (VHL) genes are intimately involved in renal cell carcinoma (RCC), including clear cell RCC (ccRCC) pathogenesis. However, the contribution of pathogenic VHL mutations to ccRCC remains poorly understood. We report a xanthoderm with non-obstructive azoospermia (NOA)-associated cystic ccRCC, and the missense VHL mutation (c. Read More

A case of cerebrotendinous xanthomatosis with brain and spinal involvement without tendon xanthomas: Identification of a novel mutation of the CYP27A1 gene.

J Clin Lipidol 2022 May-Jun;16(3):281-285. Epub 2022 Apr 3.

Department of Neurology, 417 Army Share Fund Hospital, 10-12 Monis Petraki Str., PO 11521, Athens, Greece.

Cerebrotendinous xanthomatosis (CTX) is a rare inherited disorder of the alternative pathway of bile acid biosynthesis, due to mutation(s) of the gene CYP27A1, leading to sterol 27-hydroxylase deficiency. The latter results in a systematic deposition of cholestanol and cholesterol to the central nervous system and tendons, premature cataract, as well as the manifestation of systematic symptoms, such as chronic diarrhea, osteoporosis, and premature atherosclerosis. Due to its marked clinical heterogeneity, prompt diagnosis of this disorder is challenging. Read More

Diffusion-Weighted MRI in the Genitourinary System.

J Clin Med 2022 Mar 30;11(7). Epub 2022 Mar 30.

Division of Radiology, Geneva University Hospitals and University of Geneva, 1205 Geneva, Switzerland.

Diffusion weighted imaging (DWI) constitutes a major functional parameter performed in Magnetic Resonance Imaging (MRI). The DW sequence is performed by acquiring a set of native images described by their b-values, each b-value representing the strength of the diffusion MR gradients specific to that sequence. By fitting the data with models describing the motion of water in tissue, an apparent diffusion coefficient (ADC) map is built and allows the assessment of water mobility inside the tissue.

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. Read More

[Follow-up of testicular germ cell tumors-historical aspects and current recommendations].

Urologe A 2022 May 6;61(5):484-494. Epub 2022 Apr 6.

Klinik für Urologie und Kinderurologie, Universitätsklinikum Ulm, Ulm, Deutschland.

Systematic follow-up examinations of patients cured of testicular cancer first gained attention by caregivers in the 1980s only after the management of the disease had significantly been improved by the introduction of cisplatin-based chemotherapy and almost synchronously, by the implementation of computerized tomography (CT) and serum tumor markers. Follow-up involves three aims: early diagnosis of recurrence, detection of treatment-related toxicity, and detection of secondary diseases. As the clinical presentation of testicular cancer is very heterogeneous, there is no uniform follow-up for the disease. Read More

Intravascular Ultrasound for the Evaluation and Management of Retroperitoneal, Genitourinary Malignancies.

Curr Urol Rep 2022 May 14;23(5):67-73. Epub 2022 Mar 14.

Department of Urology, Faculty Office Tower 1107, University of Alabama at Birmingham, 510 20th Street South, Birmingham, AL, USA.

Purpose Of Review: Herein we provide a review of intravascular ultrasound (IVUS) and its ability to assist in the evaluation and surgical management of advanced retroperitoneal, genitourinary tumors.

Recent Findings: Advanced retroperitoneal tumors such as advanced renal cell carcinoma, bulky retroperitoneal lymphadenopathy associated with advanced testicular carcinoma, large adrenal tumors, and retroperitoneal sarcomas can invade, compress, or distort vascular anatomy making surgical resection challenging and high risk. Intravascular ultrasonography is commonly used by vascular and cardiothoracic surgery to provide a real time assessment of vascular invasion, compression, and aberrant anatomy to assist with pre-operative and/or intraoperative decision-making.
