76 year-old female with right renal mass. Status post stroke. Hypertension. Suspected right upper pole renal mass seen on the recent ultrasound examination. This examination is limited by the absence of intravenous contrast.ABDOMEN:LUNG BASES: Mild cardiomegaly. No acute infiltrates or effusions. Dense pleural-based posterior calcification at the right lung base appears benign. Precardiac lymph nodes measure up to 1.5 cm in length.LIVER, BILIARY TRACT: No significant abnormality notedSPLEEN: No significant abnormality notedPANCREAS: No significant abnormality notedADRENAL GLANDS: No significant abnormality notedKIDNEYS, URETERS: The kidneys show moderate atrophy bilaterally. In the right midpole region there is a 3-cm diameter cystic lesion with attenuation measuring approximately 11 Hounsfield units, indeterminate. Additional smaller cystic lesions are present in the right kidney. No associated lymphadenopathy. There is a 1.6-cm exophytic mass at the left lower renal pole with attenuation of 58 Hounsfield units. These lesions could be further characterized with dedicated contrast enhanced CT or MRI, but this may not be possible due to the patient's renal failure.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Contiguous thoracic spine bridging osteophytes compatible with diffuse idiopathic skeletal hyperostosis. Degenerative changes.OTHER: Fat containing umbilical hernia. PELVIS:UTERUS, ADNEXA: Atrophic uterus. BLADDER: Bladder is contracted with apparent mild wall thickening.LYMPH NODES: No significant abnormality notedBOWEL, MESENTERY: Diverticulosis. BONES, SOFT TISSUES: Degenerative changes in the lumbosacral spine and pelvis. Old fracture deformity with callous at a right hip intertrochanteric region.OTHER: No significant abnormality noted
Bilateral renal masses. The right midpole mass appears to be an atypical cyst. The left lower pole mass is indeterminate and may be solid.
