Phlebosclerotic colitis: three cases and literature review
1Department of Radiology, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, 3 East Qingchun Road, Hangzhou, 310016, Zhejiang, People's Republic of China.
Abstract:
Three cases of phlebosclerotic colitis (PC) are presented and all in males. The etiology of the PC still remains unknown. The characteristic manifestations of PC were transmural calcifications on CT and dark purple mucosa on endoscopy. Cases 1 and 2 underwent computed tomography (CT), magnetic resonance imaging (MRI), and endoscopy while case 3 underwent CT and endoscopy. Cases 1 and 2 were admitted to our hospital for ileus. Case 3 had been diagnosed as ischemic colitis and came to our hospital for re-examination. Calcifications could be found within the colon wall and adjacent mesenteric vein from cecum to transverse colon in case 1 and from cecum to descending colon in cases 2 and 3. Extensive mural thickening of the colon could be seen on CT imaging and MRI, while dark purple mucosa was found on endoscopy in all three patients. However, their extents were more than those of calcifications. The literature is limited to a few case reports. Clinicians should be familiar with the imaging and endoscopy features of PC and radiologists should pay attention to the thickening of colon wall beside the calcifications.

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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

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.
