Diagnostic value of ultrasound in the spontaneous rupture of renal angiomyolipoma during pregnancy: A case report

Figure 1 Ultrasound images of a giant nonhomogenous lump in the left kidney area. A: The part of the lump located in the left kidney area was hypoechoic with a strong stripe echo; B: The lump caused the left kidney to move to the middle abdomen. The inner part of the lump near the left kidney was hyperechoic; C: A stripe-shaped echoless zone was seen around the lump (arrow); D: The color Doppler flow image showed some spot-like blood flow signals around the lump.

Figure 2 Computed tomography exhibited a large, mixed-density mass in the left kidney. The density of the area adjacent to the kidney was low (A), and the area far from the kidney showed high density (B).
