Answer<\/strong><\/p>\n

The ultrasound image demonstrates a simple cyst located in the cortex of the kidney. The cyst can be described as anechoic, homogenous, with thin and smooth walls, and would be a type I lesion according to the Bosniak classification system (image below). There is no evidence to suggest obstructing hydronephrosis. The Bosniak classification for renal cysts was developed in the 1980s as an attempt to standardize the description and management of complex renal lesions. Based on classification of the renal lesion, the likelihood of malignancy can also\u00a0be predicted. While the Bosniak classification was initially described and validated with CT imaging, newer data suggests that ultrasound may be\u00a0sufficient to follow renal cysts that are minimally complex (Bosniak I & II).<\/p>\n
