A 67-year-old male with Eastern Cooperative Oncology Group performance status 1 underwent renal Doppler evaluation for new-onset malignant hypertension. On Doppler imaging, there were incidental fi ndings of right lower pole and left mid-upper pole renal masses measuring 35 9 40 mm and 50 9 45 mm, respectively. The patient had a history of chronic obstructive airway disease, well-controlled type 2 diabetes, ischaemic heart disease post angioplasty, depression, obesity, obstructive sleep apnoea, and new-onset hypertension. Further investigation with MRI con fi rmed a well-circumscribed 35 9 36 9 42 mm mass in the right kidney lower pole with involvement of the pelvic fat but not the collecting system within the renal pelvis. There was a 55 9 48 9 50 mm exophytic mass, centring at the junction of the left mid and lower poles, with extension to the perinephric and pelvic fat (Fig. 1).
