56-year-old female with history of stage III chronic kidney disease. Evaluate complex cyst in left kidney. ABDOMEN:Lack of intravenous contrast limits evaluation for solid organ pathology.LIVER, BILIARY TRACT: No focal hepatic lesions. Findings suggestive of gallbladder adenomyomatosis at the fundus.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Partially exophytic complex cystic lesion in left kidney mid to inferior pole with multiple internal thin septations measures up to 3.1 x 3.8 x 3.6 cm, slightly increased in size since prior study, though comparison to prior ultrasound is difficult. The lesion demonstrates T1 hyperintensity likely due to hemorrhage and/or proteinaceous debris.Multiple bilateral simple-appearing cysts and additional smaller T2 hyperintense lesions which are too small to characterize but likely due to additional cysts. These are similar to prior study in size, though comparison to prior ultrasound is difficult. Some of these lesions demonstrate T1 hyperintensity likely due to hemorrhage and/or proteinaceous debris.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.
Complex cystic lesion in the left kidney has slightly increased in size, though comparison to prior ultrasound is difficult. Cystic neoplasm is a differential consideration and continued follow-up is recommended.
