A 44 year old lady is admitted with lower limb cellulitis and an AKI. She has a history of T2DM and is overweight. She is treated with IV antibiotics and IV fluids. Owing to her AKI, the admitting team had arranged an ultrasound of her kidneys. This demonstrated a round, smooth-walled anechoic structure in the right kidney. Further characterisation with CT showed it to be smooth and thin-walled, with no contrast enhancement.
