1. Sonographic appearance of renal masses.
Sonographic appearance of renal masses. (A) Simple cyst in the lower pole of a renal allograft (transverse view). Note the round, smooth, and thin wall and absence of internal echoes. The distal enhancement (arrows) indicates that it is fluid-filled. (B) Complex cyst in the left mid-kidney containing echogenic material (transverse view). (C) Solid mass in the right mid-kidney (longitudinal view). Note the echogenicity within the mass and the lack of distal enhancement. (D) Stone in the lower pole of a left kidney (longitudinal view) casting an acoustic shadow (arrows). There is also a simple cyst (C).
