With chronic inflammation, the bowel walls become thickened, fibrotic, and stenotic in Crohn disease, and an extension of inflammation and fistula formation often occurs as a result of a transmural fissure. (medscape.com)
A total of three colonoscopes and biopsies were performed for the patient, and the results showed multiple irregular ulcers in the whole colon ( Figure 1 ). (frontiersin.org)
Features of non-mass enhancement include its distribution, its internal enhancement pattern, and whether the enhancement is symmetric or asymmetric. (radiologyassistant.nl)
Macrophages2
This drawback is explained by immunological theory, which states that normally refluxed menstrual endometrium is cleared from the peritoneal cavity by macrophages, natural killer cells, and lymphocytes preventing endometriosis in most cases. (polradiol.com)
The inflammatory infiltrate of the lamina propria in Crohn disease leads to loose aggregations of macrophages, and they organize into noncaseating granulomas, which involve all layers of the bowel wall from mucosa to serosa. (medscape.com)
Bowel2
Small bowel adenocarcinoma (SBAC) is a rare but dreaded occurrence in CD, which generally affects males with long-standing CD, 33 times more commonly than in the general population, but is disguised by nonspecific and varied manifestations mimicking active or obstructive disease. (eurorad.org)
Sarcoidosis is a multisystemic disease of unknown etiology characterized by the formation of granulomas in various organs, especially lung and mediastinal hilar lymph nodes. (bvsalud.org)
Tract3
Another short poorly distensible ileal tract with mural thickening of lesser degree was consistent with known Crohn's disease. (eurorad.org)
Extranodal NK/T cell lymphoma is a rare non-Hodgkin lymphoma mainly involving the upper aerodigestive tract, even rarer is primary extranasal disease involving the intestine. (frontiersin.org)
The basic pathologic process of disease can occur at any segment of the alimentary tract. (medscape.com)
Clinically1
Although described and named after its author in 1932, Crohn disease was not clinically, histologically, or radiographically distinguished from ulcerative colitis until 1959. (medscape.com)
Diagnosis5
Prognosis is related to the stage of the disease at diagnosis and to initial treatment. (medscape.com)
CT plays an essential role in the diagnosis of mesenteric disease. (sajr.org.za)
Some mesenteric diseases present with distinctive imaging findings while others have similar findings, thereby complicating their differential diagnosis. (sajr.org.za)
Albeit difficult, preoperative diagnosis of malignant ECFs impacts treatment since it requires en-bloc resection plus chemotherapy. (eurorad.org)
Magnetic resonance imaging (MRI) is an excellent non-invasive modality that helps in non-invasive diagnosis, with excellent delineation of the disease extent, and thus provides a presurgical mapping of the disease, which is helpful for the operating surgeon [ 6 ]. (polradiol.com)
Segment2
Multiplanar CT-enterography (Fig. 1) with oral polyethylenglycole solution confirmed two ventral enterocutaneous fistulas with characteristic tram-track appearance, mixed fluid and air content, and showed a markedly thickened ileal segment with non-stratified enhancement which appeared to infiltrate the anterior abdominal wall. (eurorad.org)
Laparotomic en-bloc resection of ileal mass, anterior abdominal wall and subcutaneous tissue involved by enterocutaneous fistulas and a segment of transverse colon was performed (post-surgical status shown in Fig. 2a, b). (eurorad.org)
Mural1
1 cm, abrupt "shouldering" transition, lost mural stratification, soft-tissue attenuation or solid MRI signal intensity, irregular serosal nodularity, regional adenopathy [10-11]. (eurorad.org)
Infiltrate1
On CT, it appears as a well-defined or ill-defined mass showing heterogenous enhancement usually in the portal venous phase and it may infiltrate the adjacent organs. (sajr.org.za)
Heterogeneous1
They appear as solitary or multiple irregular hypoechoic masses with heterogeneous echotexture and increased echogenicity in the surrounding mesentery and omentum on USG and show increased internal vascularity on colour Doppler. (sajr.org.za)
Mesenteric3
Evaluation of the mesentery is often neglected during routine ultrasound (US) because of inadequate training and unfamiliarity with the common US features encountered with mesenteric disease. (sajr.org.za)
Note terminal ileal-wall thickening and adjacent mesenteric inflammatory stranding. (medscape.com)
Because of the transmural nature of the disease, mesenteric and perianal manifestations are fairly common. (medscape.com)
Masses2
Enhancing lesions are divided into three main categories: focus/foci, masses, and areas of non-mass enhancement (1). (radiologyassistant.nl)
Irregular masses have an uneven shape that cannot be characterized as round, oval, or lobulated. (radiologyassistant.nl)
Intestine1
Occasionally, they can be seen on laparoscopy as miliary nodules, and they function as contiguous spread of the disease from the intestine. (medscape.com)
Inflammation2
The disease is characterized by chronic inflammation extending through all layers of the intestinal wall and involving mesentery as well as regional lymph nodes. (medscape.com)
Granulomatous myopathy (GM) is a rare disease characterized by non-caseating inflammation of the skeletal muscle, with sarcoidosis as a common cause. (bvsalud.org)
Scan1
CT scan demonstrates inflammatory mass in the right lower quadrant associated with thickening of the wall and narrowing of the lumen of the terminal ileum. (medscape.com)
Chronic2
Endometriosis is a common benign and chronic inflammatory gynaecological disease due to functional endometrial glands and stroma in an ectopic location outside the uterine cavity [ 1 ]. (polradiol.com)
up to 20% of patients have chronic course of the lung disease (called advanced pulmonary sarcoidosis, APS) resulting in progressive loss of lung function, sometimes life-threatening that can lead to respiratory failure and death. (bvsalud.org)
Colon1
MRI demonstrates thickening of the wall of the right colon with intramural increased signal on a T1-weighted image. (medscape.com)
Lesions1
These lesions are typically stable on follow-up and are considered to be a part of the normal background enhancement pattern in the breast. (radiologyassistant.nl)
However, there is reduced immunological clearance of refluxed endometrium from the peritoneal cavity, causing endometriosis in some women with immune system dysfunction. (polradiol.com)
Recent studies have provided new insights into the genetic factors and immune components involved in the clinical manifestation of the disease. (bvsalud.org)
Multiple1
Focus (or when multiple, foci) is an area of enhancement measuring less than 5 mm in diameter which is too small to characterize. (radiologyassistant.nl)
Characteristics1
Just as in mammography and ultrasound, we look at its shape, its margins and its internal characteristics: this includes its T1- and T2-characteristics as well its enhancement pattern. (radiologyassistant.nl)
Large1
The image on the left shows a large, irregular mass, which proved to be an angiosarcoma. (radiologyassistant.nl)
Unknown1
Sarcoidosis is a systemic disease of unknown aetiology, which is diagnosed based on the presence of non-caseating granulomas on histology. (bvsalud.org)
Similar1
Crohn disease and ulcerative colitis share similar inflammatory changes. (medscape.com)
Development1
Genetic, infectious, immunologic, and psychological factors have all been implicated in influencing the development of the disease. (medscape.com)
