male, 23 year(s)
 
 
  • Figure 1
    Ultrasonography of the left testis

    Ultrasonography of the left testis shows multiple small, bright echogenic foci scattered through-out the whole testicular parenchyma, «snow storm» sign, characteristic of testicular microlithiasis.

     
    Area of Interest: unknown; Imaging Technique: Ultrasonography of the left testis;

    Ultrasonography of the right testis

    Ultrasonography of the right testis demonstrates an oval, isoechogenic and slightly inhomogeneous intratesticular space-occupying lesion. The lesion is surrounded by an incomplete hypoechoic rim. Absence of...

    Macroscopic radiograph

    Macroscopic radiograph of the resected right testis shows multiple small calcifications in the testicular parenchyma outside the region of the tumor.

     
    Area of Interest: unknown; Imaging Technique: Macroscopic radiograph;

    Microscopy of the testicular tissue

    Microscopy of the testicular tissue surrounding the tumor shows a calcified collagenous deposit in a seminipherous tubule (arrow). The patient underwent surgical orchiectomy of the right testis. Subsequent histology...

Ultrasonography of the left testis shows multiple small, bright echogenic foci scattered through-out the whole testicular parenchyma, «snow storm» sign, characteristic of testicular microlithiasis.
 
Ultrasonography of the right testis demonstrates an oval, isoechogenic and slightly inhomogeneous intratesticular space-occupying lesion. The lesion is surrounded by an incomplete hypoechoic rim. Absence of microlithiasis in the mass is the most striking difference with the surrounding testicular tissue.
 
Macroscopic radiograph of the resected right testis shows multiple small calcifications in the testicular parenchyma outside the region of the tumor.
 
Microscopy of the testicular tissue surrounding the tumor shows a calcified collagenous deposit in a seminipherous tubule (arrow). The patient underwent surgical orchiectomy of the right testis. Subsequent histology examination revealed a malignant teratoma and multiple calcifications in the normal testicular tissue (arrow).
