The ultrasound at the age of 17 years showed no changes when compared with the previous study at the age of 4. From Wikipedia, the free encyclopedia. It is interesting to note tesyicular among the germ cell tumours there is also stratification according to age, with some tumours being more common in some age groups than others:. Recently published guidelines from the European Association of Urology do not recommend surveillance ultrasound, testicular biopsy, routine use of tumor serum markers or CT scans for patients with isolated TM without associated risk factors, but do recommend regular self-examination 5.
Loading Stack — 0 images remaining. Testicular microlithiasis predicts concurrent testicular germ cell tumors and intratubular germ cell neoplasia of unclassified type in adults: The study revealed that both scrotal testes were heterogeneous due to the texticular of multiple echogenic spots compatible with diffuse testicular microcalcifications. It is also unclear whether early detection confers any benefit over self-exam.
However the available information is not sufficient to propose guidelines for the management of these patients. You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Metastases from testicular tumours most commonly occur to the lymphatic system followed by lung, liver and bone, and other visceral sites. Articles Cases Courses Quiz. Possible causes 2 include: The last evaluation was at 17 years of age: European Association of Urology.
Testicular microlithiasis per se is asymptomatic and is usually found incidentally when the scrotal content is examined with ultrasound, or found in association with symptomatic conditions.
Classic testicular microlithiasis is defined as five or more echogenic foci per view in either or both testes, and limited testicular microlithiasis defined as one or more echogenic foci that do not satisfy the criteria for classic testicular microlithiasis.
Support Radiopaedia and see fewer ads. There is no cure or treatment for testicular microlithiasis, however, patients may be monitored via ultrasound to make sure that other conditions do not develop. The patient was evaluated by the pediatric urologyst and a yearly ultrasound study was proposed.
Men with TM reported significantly less physical exercise than men without microliths The authors also suggest some discrepancies in food intake. Men with TM consumed more crisps and popcorn than men without TM Crisps and popcorn contain acrylamide, which is known for its potential health hazards, but according to the American Cancer Society, it is not clear whether acrylamide consumption increases the risk of developing cancer [ 12 ].
Mothers smoking during pregnancy have been associated with testicular cancer in the male offspring [ 13 ]. Pederson et al. Another potential analysed factor of TM is men's height known risk factor of testicular cancer.
There exists an interesting piece of research concerning TM and its relation to ethnicity and socioeconomic status. Based on the Pederson et al. In recent years, numerous studies have reported a relationship between TM and the risk of testicular cancer but provided ambiguous results. Currently, the most reliable data is reported by Wang et al. The meta-analyses were based on data from 12 cohort studies and 2 case-control studies involving participants. On the other hand, data published as part of a follow-up program showed controversial results.
DeCastro et al. Patel et al. In the follow-up period only 2 men 0. Afterwards, Pederson et al. In , Sharmeen et al. The foregoing studies had not found elevated tumor markers in those with incidental TM, hence monitoring serum tumor markers in follow-up is not appropriate [ 14 ]. TM association with male infertility is still debated. Evidence showed that TM was a testicular dysgenesis syndrome, which was postulated to underpin abnormalities related to male reproductive disorders [ 21 ].
The obstruction of seminiferous tubules may cause secondary inflammation, increased intraseminiferous pressure and change the blood supply of testicles. Inflammation and calcification in the seminiferous tubules area bring about deterioration in sperm quality and cause subinfertility [ 22 ]. Thomas et al.
Xu et al. TM is associated with worse semen parameters in adult men with infertility. TM was reported to be more prevalent in patients with spermatogenic defects such as severe oligospermia and reduced testicular volume [ 22 ]. Subfertility is reported to be a risk factor for a testicular tumor.
Bilateral testicular microlithiasis is indicative of CIS carcinoma in situ in subfertile men. De Gouveia Brazao et al. Therefore, the prevalence of CIS in subfertile men with bilateral testicular microlithiasis is significantly higher than in patients without testicular microlithiasis 0. An assessment of testicular microlithiasis is a valuable tool for the early diagnosis of this disease.
Those patients have an increased risk ratio of 8. Based on European data on the incidence of testicular cancer by age in the male population, follow-up for patients with TM is recommended up to the age of 55 years [ 25 ]. The presence of TM alone without any coexistence risk factors is not an indication for a regular scrotal ultrasound, it does not require biopsy or further ultrasound screening [ 26 , 27 ].
When TM is detected in conjunction with any risk factors regardless of whether it is unilateral or bilateral and provided that there is no focal mass within either testis, annual follow-up with ultrasound and monthly self-examination should be advised [ 7 ]. Recommendation for testicular biopsy in TM is still a hotly debated topic.
Patients with small or atrophic testes with microliths are at increased risk of CIS [ 30 ]. At orchidectomy in patients with germ cell tumor, if there is TM in the contralateral testis, or if the contralateral testis is atrophic, biopsy of contralateral testis may be recommended in order to look for CIS [ 7 ]. TM — testicular microlithiasis; GCT — germ cell tumor. A link between TM and testicular cancer as well as male infertility has been reported.
The clinical consequences of TM depend on the co-occurrence of specific risk factors. The presence of TM alone in the absence of risk factors is not an indication for further investigation.
Follow-up is only recommended where risk factors of testicular cancer other than TM are present. National Center for Biotechnology Information , U. Cent European J Urol. Published online Aug Author information Article notes Copyright and License information Disclaimer.
