Crohn's disease after gastroenterologist Burrill Bernard Crohn, who, in 1932, together with two other colleagues at Mount Sinai Hospital in New York, described a series of patients with inflammation of the terminal ileum of the small intestine, the area most commonly affected by the illness. Many people with Crohn's disease have symptoms for years before the diagnosis. The usual onset is between 15 and 30 years of age, but can occur at any age. Because of the 'patchy' nature of the gastrointestinal disease and the depth of tissue involvement, initial symptoms can be more subtle than those of ulcerative colitis. People with
Extrapulmonary tuberculosis in the liver or spleen, splenomegaly, splenic or lymph node calcification, inflammatory thickening of the terminal ileum and caecum, patulous I-C junction and lowattenuation lymphadenopathy may help suggest tuberculosis as the etiology of diffuse peritoneal disease. Like tuberculosis, Crohn‟s disease also can result in granulomatous peritonitis13. Smooth and regular peritoneal thickening is more in favor of granulomatous peritonitis. Extrapulmonary tuberculosis Extrapulmonary tuberculosis is tuberculosis (TB) within another location in the body than the lungs. This occurs in 15–20% of active cases, causing other kinds of TB. These are collectively denoted as "extrapulmonary tuberculosis". Extrapulmonary TB occurs more commonly in immunosuppressed
