OBJECTIVE: The objective of this study is to evaluate the imaging and follow-up findings of renal angiomyolipomas (AML) in terms of tumor size difference and developing complications.
MATERIAL AND METHODS: Changes in tumor size, complications developed during follow-up, and interventional procedures performed were retrospectively reviewed in patients with renal AML.
RESULTS: 149 patients diagnosed as renal AML by abdominal imaging. 41 (18E, 23K) of them had follow-up imaging. The mean age was 58.4 (min-max: 31-81). The mean follow-up period was 28.3 months (min-max: 3-60). Unilateral AML was found in 38 patients (93%) (21 left (51%), 17 right (41%)) and bilateral AML was found in 3 (7%) patients. The mean AML size in initial imaging was 39.2mm (min-max: 5-363). 28 cases (68%) were smaller than 40mm and 13 cases (32%) were larger than 40mm. In 32 cases (78%) the tumor size was stable. There is an increase in tumor size in 5 cases (12%) with a mean increase of 6 mm (min-max: 3-10 mm). In 3 cases (7%) bleeding was observed on follow-up. Three patients underwent arterial embolization and the mean size reduction was 12.5 mm (min-max: 10-15). 1 patient underwent surgical resection.
CONCLUSIONS: The diameter of renal AMLs are usually stable, but 12% of them may increase in size on follow-up. Interventional procedures can be performed to prevent complications such as retroperitoneal hemorrhage, renal damage in symptomatic, large-sized AML patients and progression in size on follow-up.
