RENAL ANJİOMYOLİPOM OLGULARININ 5 YILA KADAR TAKİP GÖRÜNTÜLEME BULGULARI

Öz

AMAÇ: Bu çalışmanın amacı takip görüntülemeleri olan renal anjiomyolipom (AML) olgularını tümör boyut değişikliği ve gelişen komplikasyonlar açısından değerlendirmektir.

GEREÇ VE YÖNTEM: Görüntüleme tetkikleri ile renal AML tanısı konan ve takip görüntülemeleri bulunan olguların tümör boyutundaki değişiklikler, takipte gelişen komplikasyonlar ve yapılan girişimsel işlemler retrospektif olarak incelenmiştir.

BULGULAR: Abdominal görüntüleme ile tanısı konan 149 renal AML olgusunun 41’ ine (18E, 23K) takip görüntüleme yapıldığı saptanmıştır. Ortalama yaş 58.4 (min-maks: 31-81)’ dür. Takip süresi ortalama 28.3 ay (min-maks: 3-60)’ dır. 38 olguda (%93) tek taraflı (21 sol (%51), 17 sağ (%41)), 3 olguda (%7) çift taraflı AML saptanmıştır. İlk görüntülemede ortalama AML boyutu 39.2mm (min-maks: 5-363)’ dir. 28 olguda (%68) AML boyutu 40mm’ den küçük, 13 olguda (%32) ise 40mm’ den büyüktür. 32 olguda (%78) tümör boyutu değişmemiştir. 5 olguda (%12) tümör boyutunda artış mevcut olup ortalama artış 6 mm (min-maks: 3-10 mm)’ dir. 3 olguda (%7) takipte kanama görülmüştür. 3 olguya arteryel embolizasyon işlemi yapılmış, takipte ortalama boyut azalması 12.5 mm (min-maks: 10-15)’ dir. 1 olguya cerrahi rezeksiyon yapılmıştır.

SONUÇ: Renal AML’ ların boyutu genel olarak değişmemekle birlikte %12 olguda boyut artışı görülebilir. Semptomatik, büyük boyutlu ve takipte boyut artışı gösteren AML olgularında retroperitoneal kanama ve renal hasar gibi komplikasyonlardan korunmak için girişimsel işlemler yapılabilir.

FOLLOW-UP IMAGING FINDINGS OF RENAL ANGIOMYOLIPOMA UP TO 5 YEARS

Öz

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.
