Testicular ultrasound underestimates the size of small testicular masses: a radiologic-pathologic correlation study.

World J Urol 2021 Mar 12. Epub 2021 Mar 12.

Department of Urology, The James Buchanan Brady Urological Institute, Johns Hopkins University School of Medicine, 600 North Wolfe Street, Park 213, Baltimore, MD, 21287, USA.

Purpose: Increasing use and resolution of testicular ultrasound imaging has resulted in a greater diagnosis of non-palpable small testicular masses and subsequent over-treatment with orchiectomy. Our aim was to determine the diagnostic accuracy of testicular ultrasound to accurately determine the pathologic size of small testicular masses (SMTMs) and to evaluate the association of various measurements with benign pathology.

Methods: Retrospectively, an institutional testicular cancer database was reviewed to evaluate the patients who underwent an orchiectomy for a testicular mass seen on ultrasound from 2003 to 2017. Read More

Contents of the inguinal canal: identification by different imaging methods.

Radiol Bras 2021 Jan-Feb;54(1):56-61

Universidade Estadual de Campinas (Unicamp), Campinas, SP, Brazil.

Although the correct diagnosis of inguinal hernias can often be made by clinical examination, there are several situations in which imaging methods represent the best option for evaluating such hernias, their content, and the possible complications. In addition, bulging of the inguinal region is not always indicative of a hernia, because other lesions, including tumors, cysts, and hematomas, also affect the region. The objective of this pictorial essay is to demonstrate what can be identified within inguinal hernias. Read More

The potential role of MR based radiomic biomarkers in the characterization of focal testicular lesions.

Sci Rep 2021 Feb 10;11(1):3456. Epub 2021 Feb 10.

Department of Morphology Surgery and Experimental Medicine, University of Ferrara, Via L. Ariosto 34, 44121, Ferrara, Italy.

How to differentiate with MRI-based techniques testicular germ (TGCTs) and testicular non-germ cell tumors (TNGCTs) is still under debate and Radiomics may be the turning key. Our purpose is to investigate the performance of MRI-based Radiomics signatures for the preoperative prediction of testicular neoplasm histology. The aim is twofold: (i), differentiating TGCTs and TNGCTs status and (ii) differentiating seminomas (SGCTs) from non-seminomatous (NSGCTs). Read More

Paraneoplastic limbic encephalitis as initial presentation of testicular neoplasm: A case report.

Clin Imaging 2021 Aug 3;76:61-64. Epub 2021 Feb 3.

Weill Cornell Medicine, Department of Radiology, 525 East 68(th) Street, New York, NY 10065, United States of America.

Paraneoplastic limbic encephalitis (PLE) is an immunopathologic syndrome associated with malignancy and represents a rare remote outcome of tumor on the nervous system. We report a case of PLE caused by a regressed testicular germ cell tumor in an otherwise healthy young man, who presented with acute-onset confusion, memory impairment and anterograde amnesia. Prompt recognition of PLE is critical as it allows early treatment of both the primary tumor and PLE-related neurologic impairments, which can be severe and irreversible if treatment is delayed.

Urology, Sengkang General Hospital, Singapore.

In the context of a post-treatment testicular germ cell tumour, an abdominal lesion found on surveillance CT studies led to a differential diagnosis, including recurrent germ cell tumour. We report the case of a 48-year-old man who was noted to have a new interval soft tissue lesion on a surveillance CT scan, 5 years after initial orchidectomy and chemotherapy. Excision of this lesion and histopathological review revealed an intra-abdominal desmoid. Read More

Clinical and seminal parameters associated with testicular microlithiasis and its severity in males from infertile couples.

Hum Reprod 2021 03;36(4):891-898

Andrology Unit, Department of Life, Health and Environmental Sciences, University of L'Aquila, L'Aquila, Italy.

Study Question: Is there an association of testicular microlithiasis (TM) and its severity with testicular dysfunction in men from infertile couples?

Summary Answer: The presence of ≥5 testis microcalcifications per sonogram at the scrotal ultrasonography (US) of infertile males was associated with a more severe testicular dysfunction as compared to males with limited, or without, TM.

What Is Known Already: TM, representing an incidental finding in the scrotal US, is associated with male infertility and a higher risk for testicular cancer as compared to that in infertile males without TM. Still, there are unresolved questions on the relation between TM severity and testicular dysfunction in infertile men, as well as on the identification of risk factors for TM. Read More
