inferior Vena Kava, Uterus ve Överi İnvaze Eden Retroperitoneal Leyomiyosarkom: Radyolojik Bulgular

Abstract

Retroperitoneal leyomiyosarkom nadir bir neoplazmdır. Bu lezyonlar gelişmeleri sırasında sıklıkla asemptomatik oldukları için tümör, tanı anında oldukça büyük olabilir. Leyomiyosarkom-ların yaklaşık üçte ikisi retroperitoneal boşlukta bulunur. Cerrahi rezeksiyon bir tedavi seçeneğidir ve lokal rekürrensi önlemek ve iyi sonuçlar elde etmede en önemli faktör kitlenin tamamen çıkarılmasını başarmaktır. Bununla birlikte, inferiyor vana kava veya renal venleri etkileyen çevre doku invazyonu mevcut ise kitlenin tamamen çıkarılması bazen güç olabilir. Biz burada, 38 yaşındaki bayan hastada histopatolojik olarak retroperitoneal leyomiyosarkom olduğu kanıtlanmış olgunun görüntüleme bulgularını sunmaktayız. Aynı zamanda, farklı görüntüleme modalitelerinin (ultrasonografi, Doppler ve çok kesitli bilgisayarlı tomografi) faydalarını da tartıştık.

Retroperitoneal Leiomyosarcoma Invading the Inferior Vena Cava, Uterus and Ovary: Radiologic Findings: Case Report

Abstract

Retroperitoneal leiomyosarcoma is a rare neoplasm. Because these lesions are often asymptomatic during growth, the tumor can be massive at the time of diagnosis. About two thirds of leiomyosarcomas are found in the retroperitoneal space. Surgical resection is the treatment of choice, and the most important factor in preventing local recurrence and attaining a good outcome is to be able to remove the tumor completely.; however, complete removal is sometimes difficult if there is an invasion of the surrounding tissues, affecting the inferior vena cava or renal veins. In this case report, imaging findings of a histopathologically proven retroperitoneal leiomyosarcoma in a 38-year-old woman are presented. Also, the benefits of different imaging modalities (Ultrasound, Doppler and MDCT) in the diagnosis are discussed. Nilgün IŞIKSALAN ÖZBÜLBÜL, Muharrem TOLA, Tülay TEMUÇİN, Levent IŞIKAY,
