Presentation
Complex cyst identified on ultrasound.
Patient Data
Right kidney measures 10.1 x 4.8 cm, normal in size and cortical thickness. A 5.0 x 4.2 cm exophytic solid heterogeneously enhancing mass lesion with cystic areas within is seen arising from mid pole anterolateral cortex. 4.6 x 3.6 cm exophytic simple cortical cyst in lower pole. No local infiltration. Patent renal vein. 23 x 14 mm portal enlarged lymph node. Lower pole caliectasis No calculi or hydronephrosis. Normal corticomedullary differentiation. Normal excretion.
Right ureter is normal in course and caliber.
Left kidney measures 10.4 x 4.8 cm, normal in size and cortical thickness. No calculi or hydronephrosis. Normal corticomedullary differentiation. Normal excretion.
Left ureter is normal in course and caliber.
Annotated positive findings.
Case Discussion
Solid lesion with arterial enhancing areas, with non enhancing areas being more evident on portal-venous phase, is highly likely to turn out to be a malignany neoplasm. Important to rule out any renal vein invasion. Only one large porta hepatis lymph node is identified.
