Focal patch

Definite diagnostic criteria for BWI have not been determined, but it should be restricted to an active enteritis that involves the ileum in a contiguous pattern from the cecum and has a similar or greater degree of inflammation. Endometriosis is defined by the presence of endometrium outside the uterus, and most commonly involves nulliparous women 25 to 45 years of age.

Endometriotic tissue in the ileum may undergo cyclic hormonal changes, with periodic hemorrhage. When the muscularis propria is involved, there is marked muscular hypertrophy and a fibrotic reaction in bowel wall, leading to an appearance of an extrinsic mass effect or segmental narrowing.

On tissue biopsy, if only the mucosa is sampled, the typical lesions in the muscularis propria may be missed. In this regard, radiographic imaging can be helpful.

In indeterminate cases, diagnostic laparoscopy is recommended [ 51 ]. Beyond infections, systemic disorders including spondyloarthropathies, vasculitides, ischemia, and amyloidosis as well as medications may lead to ileal inflammation. The diagnosis of the cause of ileitis is of paramount importance because misdiagnosis may result in critical delays or errors in management.

The specific diagnosis is suggested by the clinical disease course, presence of other systemic manifestations, appearance of imaging and endoscopic findings, and histologic results.

Infectious Yersinia spp. Salmonella spp. Open in a separate window. Infectious Ileitis Yersinia Yersinia enterocolitica and Yersinia pseudotuberculosis are acquired by ingestion of contaminated food eg, raw vegetables, milk products, and raw pork intestines [chitterlings] or water.

Salmonella Nontyphoidal Salmonella , the most commonly identified cause of foodborne illness in the United States, occurs after ingestion of contaminated food products of animal origin eg, eggs, dairy products, poultry, or ground meat. Clostridium difficile Clostridium difficile typically causes antibiotic-associated colitis.

Mycobacterium avium-intracellulare complex Disseminated Mycobacterium avium-intracellulare complex MAC occurs predominantly in persons with AIDS or immunosuppressing conditions. Actinomycosis Actinomycosis is a chronic bacterial infection caused by a heterogenous group of anaerobic gram-positive bacteria.

Anisakiasis GI anisakiasis is acquired after ingestion of raw marine fish or squid infested with larvae of the roundworm Anisakis simplex herring worm or Pseudoterranova decipiens cod worm. Histoplasmosis Histoplasma capsulatum is a dimorphic fungus that exists in mold form in soil contaminated with bird or bat droppings, and transforms to yeast form when inhaled.

Ileitis Associated with Spondyloarthropathies Spondyloarthropathies SpA are characterized by inflammation of axial joints, asymmetric oligoarthritis, and enthesitis. Vasculitides Vasculitides that are primary to the intestine or occur secondary to systemic vasculitis represent a rare cause of ileitis. Ischemia Other conditions aside from vasculitis cause ischemic ileitis. Other causes of drug-related ileitis Potassium chloride KCL tablets are a rare cause of ileitis.

Infiltrative Causes of Ileitis Eosinophilic gastroenteritis Eosinophilic gastroenteritis EG is a rare disorder characterized by prominent eosinophilic infiltration of the GI tract in the absence of known causes of eosinophilia eg, parasitic infection, malignancy, and drug reaction. Sarcoidosis Sarcoidosis is a chronic, multisystemic, granulomatous disease most commonly involving the lung, lymph nodes, spleen, and skin.

Amyloidosis Amyloidosis is characterized by the extracellular deposition of protein in an abnormal fibrillar form. Other Causes Backwash ileitis Backwash ileitis BWI refers to inflammation in the distal few centimeters of terminal ileum in patients with ulcerative colitis [ 49 ].

Endometriosis Endometriosis is defined by the presence of endometrium outside the uterus, and most commonly involves nulliparous women 25 to 45 years of age.
