MRI Diagnosis of Giant Renal Hamartoma With Renal Venous Tumor Thrombus: Report of One Case and Literature Review.

This paper reported a case of giant renal hamartoma complicated with renal venous tumor thrombus.MRI was used for diagnosis and renal function evaluation on the affected side before surgery,and the patient underwent robot-assisted laparoscopic radical resection of the left kidney and left renal venous tumor thrombus embolectomy.The operation was successfully completed,and there were no complication or tumor recurrence during the 20-month follow-up after surgery.This case,combined with the literature review,suggests that MRI has important guiding significance in the preoperative evaluation and surgical modality selection of giant renal hamartoma.
