 | Media file 1: Renal ultrasonogram obtained in a 12-year-old boy with known tuberous sclerosis. Note the multiple echogenic tumors of varying sizes in both kidneys (see also Images below). This oblique sagittal scan through the left kidney shows a 4-cm echogenic mass (arrow) on the inferior aspect of the kidney that anteriorly displaces the renal sinus (S). |
 | Media file 2: Renal ultrasonogram depicting many tumors in the right kidney. The arrow marks an echogenic 1-cm lesion. (Image above and 2 below were obtained in the same patient.) |
 | Media file 3: Selective right renal angiogram showing multiple avascular tumors. The tumors are small. (Images above and one below were obtained in the same patient.) |
 | Media file 4: Selective left renal angiogram showing 2 tumors, which are larger than those in Image 3. The final diagnosis was multiple renal angiomyolipomas in a patient with tuberous sclerosis. (Images above were obtained in the same patient.) |
 | Media file 5: Computed tomography scan obtained in a 15-year-old boy with tuberous sclerosis (under surveillance). The image shows rapid growth in a right renal lesion with mixed attenuation. The final diagnosis was tuberous sclerosis–associated angiomyolipoma. |
 | Media file 6: Computed tomography (CT) scan obtained in the same patient as in Image above. The image shows the technique of CT scanning-guided biopsy with a Tru-cut needle. |
 | Media file 7: Nonenhanced axial computed tomography scan through the kidneys. The image shows a space-occupying lesion of mixed attenuation interspersed with areas of fat attenuation. The final diagnosis was sporadic angiomyolipoma. |
 | Media file 8: Contrast-enhanced axial computed tomography scan obtained through the kidneys in the same patient as in Image above. The image shows patchy tumor enhancement, with displacement of part of the normal lateral aspect of the renal cortex. |
 | Media file 9: Nonenhanced computed tomography (CT) scan obtained in a 28-year-old pregnant woman (at 26 weeks' gestation) who presented with sudden-onset right upper quadrant abdominal pain and hypotension. An ultrasonogram (not shown) depicted a complex mass that replaced the right kidney; this finding was suggestive of a tumor that had ruptured into the perinephric space and retroperitoneum. This CT scan, obtained through the mid portions of the kidneys, shows a mixed-attenuation mass interspersed with areas of low attenuation (fat) and areas of high attenuation (blood). |
 | Media file 10: Enhanced computed tomography scan obtained in the same patient as in Image 9. The image shows patchy renal cortical enhancement around the tumor. Note the retroperitoneal stranding behind the tumor. The final diagnosis was spontaneous rupture of an angiomyolipoma. |
 | Media file 11: Ultrasonogram obtained in a 48-year-old man who presented with dyspepsia and right upper quadrant discomfort. The patient was referred for a gallbladder ultrasonogram. The gallbladder was normal, but a solid 18-mm mass was present in the upper pole of the right kidney; it was isoechoic relative to the renal sinus. |
 | Media file 12: Part of an intravenous urogram series obtained in the same patient as in Images 11, 13-14. The radiograph shows a hypoattenuating exophytic mass (arrow). |
 | Media file 13: Nonenhanced axial computed tomography scan obtained through the upper pole of the kidneys in the same patient as in Images 11-12 and 14. Image shows a hypoattenuating (15 HU) exophytic mass (arrow). |
 | Media file 14: Axial fat-suppressed magnetic resonance image obtained through the upper poles of the kidneys in the patient in Images 11-13. Image shows a lesion of high signal intensity with tiny areas of intratumoral fat (which had low signal intensity on fat-suppressed images). The final diagnosis was renal cell carcinoma with fatty metamorphosis. |
