Abstract:
Colonic intramural hematoma is a rare condition and its endoscopic and radiological findings remain poorly described. An 82-year-old woman was hospitalized with a diagnosis of acute cerebral infarction. She immediately received anticoagulant therapy with argatroban for 1 week. With the appearance 4 days later of hematochezia, she was found to have severe anemia. Following insertion of the colonoscope, a large submucosal hematoma was shown to be present in the descending colon, with the mucosa shown to be necrotic and the residual mucosa around the hematoma shown to be yellowish. Computed tomography revealed a hyperdense mass in the descending colon. Laparoscopic colectomy was performed for the lesion diagnosed as intramural hematoma. Pathologically, it was a hematoma located in the subserosal layer involving full-thickness hemorrhage. To our knowledge, this report represents a valuable addition to the literature describing a case of colonic intramural hematoma whose diagnosis was effectively established by the combined use of CS and CT.

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...
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...

Histology of the Large Intestine
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...
