History of a renal lesion. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology, signal intensity and size. No focal suspicious lesion, biliary ductal dilatation or vascular abnormality. The gallbladder is normally distended.SPLEEN: 3.0 x 2.8 x 2.6 cm T1 hypointense and T2 hyperintense lesion in the superior spleen with multiple internal septations which enhance on postcontrast imaging. No additional splenic lesion.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Left inferior pole exophytic T1 hyperintense and T2 isointense lesion measuring 2.2 x 2.0 cm (series 6/43) demonstrating no definite postcontrast enhancement suggesting a proteinaceous/hemorrhagic cyst. However evaluation for enhancement is limited by lack of subtraction images and the lesions intrinsic T1-weighted hyperintensity. The renal vessels are unremarkable. No regional lymphadenopathy.Left inferior pole parapelvic T1-weighted intermediate and T2-weighted mildly hyperintense lesion measuring 1.1 cm without post-contrast enhancement, compatible with a hemorrhagic/proteinaceous cyst.Bilateral nonenhancing T2 hyperintense and T1 hypointense lesions, the largest on the right measuring 2.6 x 1.9 cm and 1.1 x 1.4 cm on the left compatible with cysts without internal complexity.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Probable complex hemorrhagic/proteinaceous cyst in the lower pole of the left kidney without definite enhancement, although this is limited by lack of subtraction images and its intrinsic T1 hyperintensity. A repeat MRI with subtraction images is recommended to assess for enhancement.2.Left parapelvic hemorrhagic/proteinaceous cyst.3.Multiseptated 3.0 cm splenic lesion without internal enhancement may reflect a complex splenic cyst or lymphangioma.
