Abstract:
A woman in her thirties was diagnosed as Takayasu's arteritis (TAK) by dilatation, wall thickness of her abdominal aorta in contrast-enhanced computed tomography. Although she didn't have any subjective bowel symptoms, fluorodeoxyglucose (FDG)-positron emission tomography (PET) also revealed uptake of FDG in descending colon, and colonoscopy revealed aphthous colitis. After the start of steroid therapy, both arteritis and colitis were improved. FDG-PET can detect TAK and inflammatory bowel diseases at an early stage. FDG-PET is a less invasive module with a high sensitivity for detecting colitis, therefore should be considered for TAK even without physical colon symptoms.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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...

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...
