Abstract
Graft-versus-host-disease (GVHD) is a common complication of hematopoietic stem-cell transplant with reported incidence of 30% to 50% in HLA-match recipients and up to 50%-70% in unmatched recipients. GVHD can also be seen as a complication of thymus transplantation or blood transfusions in immunocompromised patients. Although it can involve any organ, but commonly involves the skin, liver and gastrointestinal tract. GVHD results from donor T-cells reacting to recipient antigen leading to a cascade of immune-modulated events resulting in damage to involved host-organ(s). There are two forms of the disease: acute GVHD which occurs within first one-hundred days post-transplant or chronic GVHD which occurs after one-hundred days post-transplant. Our exhibit is a case-based review of gastrointestinal tract and hepatobiliary manifestations of GVHD. We will review common clinical presentation, pathophysiology, histology, and demographics of gastrointestinal and hepatobiliary GVHD. There will be special emphasis on imaging (CT, MRI, and endoscopy findings) along with histopathology correlation of the imaging findings. Additionally, there will be extensive case-based discussion on differential diagnostic considerations including: pseudomembranous colitis, typhilitis, cytomegalovirus colitis, radiation enteritis, posttranplantation lymphoproliferative disorder (PTLD), shock-bowel (hypoperfusion complex), viral hepatitis (CMV, HSV, VZV, EBV), thromboembolism, and drug induced (bactrim, itraconzole, chemotherapy agents, etc.). Clinical features, pathophysiology, imaging findings along with histologic correlation, treatment and prognosis of these differential diagnoses will be discussed. By the conclusion of this presentation, the physician should have a better understanding of gastrointestinal and hepatobiliary GVHD and characteristic imaging findings. Although GVHD carries a broad differential diagnosis, it can be narrowed utilizing age, clinical features, imaging (radiologic and endoscopy findings).
