Abstract
Bone marrow transplantation(BMT) is widely used in the treatment of hematologic disorders and some solid tumors in children. A wide variety of complications may occur in BMT recipients and are a major cause of morbidity and death. The gastrointestinal tract is a frequently affected organ after BMT. Gastrointestinal complications include neutropenic colitis, CMV enterocolitis, pseudomembranous colitis, GVHD, pneumatosis intestinalis and post-transplantation lymphoproliferative disease (PTLD). In pediatric age, ultrasonography is used for modality of choice and essential tool for diagnosing these complications in critically ill recipients. We present US features of these many gastrointestinal complications with correlative other abdominal imaging, including plain radiography, contrast studies and enhanced CT scans.
