The “striated” testis

Excerpt

The “striated” testis refers to a specific ultrasound appearance of a pattern of alternating lines of differing echogenicity within the testicular parenchyma (Fig. 1a, b) [1]. These striations are seen along the anatomic distribution of the interlobular septa extending from the mediastinum testis [1], in a pattern likened to the stripes of a zebra’s coat (Fig. 2). This appearance can be unilateral or bilateral and may involve the entire testis or only a portion of it [2]. While initially described in a case of testicular fibrosis, the striated appearance may also be seen in the setting of infection, infarction, trauma, or neoplasm, including non-Hodgkin’s lymphoma [1‐3]. Clinical features and the presence of additional sonographic findings, such as focal mass or abnormal testicular size or vascularity, can help narrow the differential diagnosis [1].
