Hypoechoeic focus in the left kidney,,may reflect Focal Calietasia Vs a cyst....2.unremarkable right kidney...3..other details as discussed..,thank you
HelloYour findings may indicate small hypoechoic (dark)lesion in upper pole of left kidney. It may be due to simple renal cyst or focally dilated calyx. Both are generally benign findings, and it only requires follow-up ultrasound. Simple renal cysts are generally developmental findings and these are asymptomatic in nature. You may need clinical evaluation. Cyst may cause symptoms if there is infection in cyst or rapid increase in size. As lesion is small in your case, I suggest for follow-up ultrasound only. Intervention is only required in complicated cases. Get well soon. Take Care Chat Doctor.
