Abstract:
Graft-vs-host disease (GVHD) is a common, life-threatening complication of bone marrow transplantation that frequently involves the gastrointestinal tract. Since symptoms are typically nonspecific, radiologic examination is often performed to reach a diagnosis. To the best of our knowledge, this is the first reported radiologic description of a case of rectal involvement as the first manifestation of GVHD. The differential diagnosis of segmental rectal wall thickening in a patient following bone marrow transplantation should include GVHD.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
