Summary:

Description
  • Radiopaedia case ID: 85004
  • Image ID: 54046269
  • Image stack position: 35/61
  • Plane projection: Sagittal
  • Aux modality: C+ arterial phase
  • Study findings: Findings: Large lobulated exophytic mass lesion measuring 10 x 8.8 x 8.5 cm is seen at the lower pole of the right kidney. Two tiny calcification foci are seen in it. It has an enhancing (non-contrast density=20 HU, Venous phase density=82 HU) peripheral solid component and non-enhancing irregular necrotic center. The mass is grossly extending beyond the renal capsule, has mild perinephric fat stranding. However, it is still confined within Gerota's fascia. Some prominent arteries & veins (neo-vascularity) are seen along the inferior aspect of this mass lesion. A prominent draining vein is seen at the inferior aspect of this mass, which is draining to the inferior vena cava via the right ovarian vein. The mass is compressing the lower pole calyceal system and the renal pelvis; however, no invasion/infiltration of the collecting system or hydronephrosis is seen. No clear signs of the adjacent renal vein or IVC thrombosis. No evidence of local or distant metastasis is seen. A small simple cyst is seen in either kidney.  Multiple focal radiolucent lesions with polka dot sign in the axial images are seen in the T11, T12, L1, and L2 vertebral bodies; these are likely vertebral hemangiomas. Impression: Large heterogeneous right renal mass, suspicious of renal cell carcinoma. Note: This is an old case. Unfortunately the "axial venous phase images" are not available.
  • Modality: CT
  • System: Oncology
  • Findings: A large exophytic lobulated heterogeneous solid mass lesion measuring 7.9 x 8.4 cm is depicted along the mid/lower pole of the right kidney. Small fluid echogenicity areas, likely representing necrosis, are seen within the center of this lesion. Some vascularity is seen in its peripheral part on Doppler ultrasound examination. Impression: Highly suspicious right renal mass lesion.
