These findings are characteristic of angiomyolipomata. Small lesions of fatty density are also noted within the liver on coronal images, which may indicate associated hepatic angiomyolipomas.\u003c/p\u003e\u003cp\u003eThe presence of bilateral renal\u0026nbsp;angiomyolipomas, as well as hepatic angiomyolipomas and the history of seizures, is suspicious\u0026nbsp;tuberous sclerosis, which was confirmed in this case. Tubers were identified on cerebral MRI and thoracic CT scan identified cystic lesions in both lower lobes in relation to lymphangioleiomyomatosis, all within the spectrum of tuberous sclerosis.\u003c/p\u003e\u003cp\u003ePolycystic kidney disease would be observed as cystic lesions. On the other hand, both renal and urothelial carcinoma would not have a macroscopic fat component, and bilaterality would be a rare presentation.\u0026nbsp;\u003c/p\u003e","id":1621,"imageUrl":"https://prod-images-static.radiopaedia.org/multiple_choice_questions/149/AML_RP_big_gallery.jpeg","imageAttribution":{"kind":"own","user_id":45033,"user_param":"edlomar","user_name":"Edgar Lorente"},"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2003","nextQuestionPath":"/articles/renal-angiomyolipoma/questions/1546","relatedArticles":[{"id":2224,"title":"Tuberous sclerosis","link":"/articles/tuberous-sclerosis?lang=us"},{"id":7534,"title":"Renal cell carcinoma","link":"/articles/renal-cell-carcinoma-1?lang=us"},{"id":4950,"title":"Autosomal recessive polycystic kidney disease","link":"/articles/autosomal-recessive-polycystic-kidney-disease?lang=us"},{"id":10257,"title":"Autosomal dominant polycystic kidney disease","link":"/articles/autosomal-dominant-polycystic-kidney-disease-1?lang=us"},{"id":9813,"title":"Transitional cell carcinoma (urinary tract)","link":"/articles/transitional-cell-carcinoma-urinary-tract?lang=us"}],"alsoUsedIn":[],"stem":"\u003cp\u003eThis 35-year-old woman presented with abdominal pain and a prior history of seizures.
