Magnetic resonance imaging findings of primary hepatic lymphoma

Öz

Primary hepatic lymphoma is a very rare entity and ac­counts for less than 1% of all extranodal lymphomas. A higher incidence is seen in patients that are immunocom­promised, such as transplant recipients and patients with increased exposure to viruses such as Epstein- Barr vi­rus, human immunodeficency (HIV), or hepatitis viruses. The majority are large B-cell lymphomas. The differential diagnosis for primary hepatic lymphoma is quite broad, including other primary and secondary hepatic malignan­cies, as well as infectious and inflammatory processes. In this study, a case of man with solitary primary hepatic lymphoma is presented magnetic resonance imaging findings.

Primer hepatik lenfomanın manyetik rezonans görüntüleme bulguları

Öz

Primer hepatik lenfoma oldukça nadir görülen bir antite olup tüm ekstranodal lenfomaların %1\'inden azını oluş­turur. Primer hepatik lenfoma, Epstein–Barr virus, human immunodeficency virüs (HIV) yada hepatit virüslerine ma­ruz kalmış transplantasyon hastaları gibi immün sistemi baskılanmış hastalarda daha yüksek insidansta görülür. Büyük çoğunluğu B hücreli lenfomalardan oluşur. Ayırı­cı tanısı infeksiyöz ve inflamatuar süreçler ile karaciğerin primer ve sekonder tümörlerine kadar geniş bir yelpazeyi içermektedir. Bu çalışmada soliter primer hepatik lenfo­malı bir olgunun manyetik rezonans görüntüleme bulgu­ları sunulmaktadır.
