What are the characteristics of an anechoic cyst, reticular/lacy/fish net appearance, and ground glass appearance in ultrasound?
Understand the Problem
The image provides ultrasound (US) findings related to different types of cysts and appearances. It describes specific characteristics of the findings, such as anechoic cysts, and their relationship with T1 and T2 MRI sequences.
Answer
Anechoic: fluid-filled, acoustic enhancement. Reticular: hemorrhagic. Ground glass: endometrioma.
Anechoic cysts are fluid-filled with posterior acoustic enhancement. Reticular/lacy pattern may indicate a hemorrhagic cyst. Ground glass appearance is typical for endometriomas, showing diffuse low-level echoes.
Answer for screen readers
Anechoic cysts are fluid-filled with posterior acoustic enhancement. Reticular/lacy pattern may indicate a hemorrhagic cyst. Ground glass appearance is typical for endometriomas, showing diffuse low-level echoes.
More Information
Anechoic cysts appear black on ultrasound due to being filled with fluid, causing sound waves to pass through, creating posterior enhancement. Reticular patterns often result from blood clots or fibrin strands in hemorrhagic cysts. Ground glass appearance in endometriomas results from compacted blood or endometrial tissue.
Tips
Confusing the appearance of different cysts during ultrasound interpretation can lead to misdiagnosis. Ensure clear understanding of acoustic characteristics.
