A Case Report of Nodular Regenerative Hyperplasia and Non-cirrhotic Portal Hypertension Post Oxaliplatin Chemotherapy.

Oxaliplatin is widely used in chemotherapeutic regimens for colorectal carcinoma, its recurrence, and metastasis, and is associated with better outcomes. However, oxaliplatin use is associated with injury to hepatic sinusoidal endothelium and the development of nodular regenerative hyperplasia (NRH) in the liver, which can be differentiated from nodular hyperplasia of cirrhosis by the presence of diffuse micronodular transformation without a fibrous band and the lack of perinuclear collagen tissue. This causes non-cirrhotic portal hypertension (NCPH), which presents with splenomegaly and variceal bleeding and preserved synthetic liver function. Its treatment revolves around managing variceal bleeding with banding, sclerotherapy, and beta blockers. Some patients may end up requiring liver transplantation because of recurrent variceal bleeding. We present the case of a 46 years old female who presented with recurrent variceal bleeding due to NCPH and NRH six years after treatment of colon carcinoma with oxaliplatin.
