Abstract

In this report we describe the magnetic resonance (MR) angiographic features of benign hepatic nodules that developed in a patient with Budd-Chiari syndrome, and present the distinguishing features of benign regenerative nodules from hepatocellular cancer. In a 27-year-old woman with chronic Budd-Chiari syndrome, previously non-existing benign nodules developed in the liver parenchyma during the 10-month period following transjugular intrahepatic portosystemic (TIPS) shunt placement. The liver had been examined with gray-scale and Doppler sonography in addition to the MR imaging and MR angiography. On MR angiography, more hepatic nodules became visible in the portal venous phase compared to that of the arterial phase. Delayed washout of contrast medium in nodules was considered to be due to stasis in hepatic sinusoids. Hypervascularization, appearance after portosystemic shunt creation, multiplicity, small size ( <=2 cm in diameter in our patient), presence of peripheral rim, and high signal intensity on T1-weighted images are important imaging features of benign hepatic nodules that develop in patients with Budd-Chiari syndrome.

Özet

Budd-Chiari sendromunda TIPS şant işlemi sonrasında gelişen benign rejeneratif nodüllerin kontrastlı MR anjiografi ile görüntülenmesi Budd-Chiari sendromu olan bu olguda, karaciğerde gelişen benign rejenerasyon nodüllerin daha önce literatürde tanımlanmayan kontrastlı MR anjiografi bulguları vurgulanmış ve benign nodüllerin hepatosellüler karsinomadan ayırtıcı özellikleri sunulmuştur. Budd-Chiari sendromu tanısı ile TIPS yapılan 27 yaşındaki kadın hastada 10 ay sonra karaciğerde benign rejeneratif nodüller ortaya çıkmıştır. Hastanın karaciğeri, ultrasonografi, renkli Doppler ultrasonografi, MR görüntüleme ve MR anjiografi ile incelenmiştir. MR anjiografide, IV kontrast madde uygulamasını takiben portal venöz evrede, arteriyel evreye göre daha fazla nodül boyanarak görünür hale gelmiştir. Muhtemelen hepatik sinüzoidlerdeki staz nedeniyle, nodüllerin kontrast maddeyi bırakması gecikmiştir. Nodüllerin hipervasküler, çok sayıda ve küçük boyutta (bizim hastamızda 2 cm’den küçük) olmaları, portosistemik şant sonrası ortaya çıkmaları, periferlerinde halkasal sinyal intensite farkı bulunması ve T1 ağırlıklı görüntülerde yüksek sinyal şiddeti göstermeleri Budd-Chiari sendromunda gelişen hepatik benign rejenerasyon nodüllerinin özellikleridir.
