Overview

Pattern of echogenicity of an adrenal hematoma depends on its age
- Early-stage hematoma appears solid with diffuse or inhomogeneous echogenicity.
- As liquefaction occurs, the mass demonstrates mixed echogenicity with a central hypoechoic region and eventually becomes completely anechoic and cystlike.
- Calcifications may be seen in the walls of the hematoma as early as 1–2 weeks after onset and gradually compact as the blood is absorbed.
Color Doppler and power Doppler imaging allow confirmation of the avascular nature of the mass.
