Cystic anechoic areas typically refer to fluid-filled lesions in the liver as described by ultrasound. These usually indicate organ cysts, but the specific type depends on the location of the cystic anechoic area, the patient's medical history, and other factors. If the patient has no other abnormalities, these cystic anechoic areas are generally congenital cysts or degenerative changes in the organ. For patients who have undergone surgery, these could also be localized encapsulated fluid collections. In some cases, they might represent vascular malformations. Generally, these cystic anechoic areas are benign. Patients can opt for regular follow-ups or undergo additional imaging studies, such as CT or MRI, for further evaluation.
