Testicular sonogram.

Precise localization, detection, and recognition of minor changes in testicular lesions are important because teratocarcinoma is notorious for manifesting as secondaries at the time the primary site is obvious to the clinician. In the past, questionable enlargement of the testis due to significant pathology required numerous radiographic invasive special procedures to provide a correct diagnosis. Due to the advent of the sophisticated digital ultrasound imager with high frequency quarter wave transducer, it is possible to detect minor changes in the tissue character of the testis, thus enabling the physician to tackle primary neoplasms prior to distant spread.In our case we were able to detect the abnormality in the testis, but unfortunately a large secondary abnormal mass was present. Even at that stage we were able to map out the extent of the lesion which was beneficial to the surgeon and the patient. Ultrasound studies were utilized in serial follow-up studies.
