New reference charts for testicular volume in Dutch children and adolescents allow the calculation of standard deviation scores

Aim Accurate calculations of testicular volume standard deviation (SD) scores are not currently available. We constructed LMS-smoothed age-reference charts for testicular volume in healthy boys. Methods The LMS method was used to calculate reference data, based on testicular volumes from ultrasonography and Prader orchidometer of 769 healthy...

Prevalence of testicular microlithiasis in males aged 0 to 18 years referred for scrotal sonography

Background: Testicular microlithiasis (TM) is a relatively uncommon and usually asymptomatic condition that is characterized by multiple 1-3 mm nonshadowing echogenic foci within the parenchyma of the testis. Objectives: The prevalence of testicular microlithiasis was assessed retrospectively in males ranging from 0-18 years who had been...

Testicular microlithiasis in two boys with a chromosomal abnormality

A nine and 13-year-old boy, previously diagnosed with 18q syndrome and an 11q deletion, respectively were diagnosed with testicular microlithiasis (TM). Both cases demonstrate that TM occurs in patients with various chromosomal abnormalities.

Testicular microlithiasis in boys and young men with congenital or acquired undescended (ascending) testis

Purpose: We assessed the prevalence of testicular microlithiasis by ultrasound in boys and young men with congenital or acquired undescended (ascending) testis. Materials and Methods: During followup for testicular growth patients with congenital or acquired undescended (ascending) testis were also screened by ultrasound for testicular...

Prevalence of testicular microliathesis in asymptomatic males 0 to 19 years old

Purpose: We assessed the prevalence of testicular microlithiasis via ultrasound in asymptomatic males 0 to 19 years old. Materials and Methods: We studied only patients with 2 scrotal testes at birth and at examination. We excluded boys with a history of undescended testis, hydrocele, varicocele and syndromes associated with testicular...

Ascent of the testis revisited: Fact not fiction

Testiculaire microlithiasis bij jongens [Testicular microlithiasis in boys]

In three boys aged 15, 9, and 10 years respectively scrotal ultrasound revealed testicular microlithiasis (TM). Two boys were free of symptoms and one suffered from testicular pain. TM is characterized by multiple echogenic foci within the seminiferous tubules with no acoustic shadowing. The pathophysiology is largely unknown. In adult men, TM...

Testicular microlithiasis in a 2-year-old boy with pseudoxanthoma elasticum

Pseudoxantoma elasticum (PXE) is a rare chromosomal disorder that results in mineralization of elastic fibers, especially in the skin, eye, and cardiovascular system. Recently, PXE has been associated with testicular microlithiasis (TM),1 which itself might be associated with testicular malignancy.2 Here we report on a 9-year-old boy with PXE...
