Renal cyst

A renal cyst is a fluid-filled sac that forms in the kidney, a common finding in abdominal ultrasound examinations. These benign, non-cancerous cysts are typically anechoic (black) on ultrasound, with smooth, thin walls and posterior acoustic enhancement, indicating a clear fluid content. Understanding renal cysts is crucial for medical professionals as they differentiate from solid masses or other kidney pathologies, guiding appropriate patient management.

Often discovered incidentally during routine abdominal scans, simple renal cysts rarely cause symptoms or require intervention. However, atypical cysts may warrant further investigation to exclude complex conditions or malignancy. Ultrasound plays a vital role in their characterization, providing real-time imaging to assess size, number, and features, ensuring accurate diagnosis and follow-up in abdominal imaging.
