A 43-year-old male underwent ultrasound examination of the abdominal cavity, which revealed a presence of well demarcated, hypoechogenic, somewhat heterogeneous solid mass, 9 cm in diameter (Figure 1).
Abdominal CT with contrast. Coronal multiplanar reconstructed CT image. Unenhanced CT scan of the abdomen shows a well defined, hypodense, homogeneous mass with density of 20HU.Unenhanced CT scan shows homogeneous.

Discrete, linear areas of contrast enhancement were visible in the late phase, about 10 min. after administration of contrast agent (Figure 3).
Coronal T1-weighted image shows a homogenous mass with homogeneously low signal intensity.
