Acoustic Streaming A Diagnostic Clue to Diagnosing Testicular Teratoma

Abstract

Teratomatous tissue is commonly seen in a variety of malignant testicular tumors, and while the exact determination of testicular tumor subtypes heavily relies on pathologic diagnosis, ultrasound remains the gold standard in the initial evaluation of such entities. The major groups of testicular tumors may demonstrate characteristic features which can point the radiologist toward a more pruned differential diagnosis. While it is important for the interpreting physician to be aware of such features, it is of equal necessity that they are aware of potential visual phenomena, such as acoustic streaming in the diagnosis of testicular tumors. We present a case of a testicular teratoma with acoustic streaming. This testicular tumor was confirmed to be predominantly a teratoma with a minimal element of seminoma on histopathology.
