Tuberculous mesenteric lymphadenitis

Primary tuberculous mesenteric lymphadenitis is caused by the spread of tuberculosis or the intestinal mucosa into the corresponding lymph nodes, or the original lesions of the intestinal wall have completely healed without leaving traces. Secondary is also secondary to tuberculosis or intestinal tuberculosis. Usually the number of affected lymph nodes varies in size and size; it is pale yellow, off-white, or pink, and easily fuses together into a mass, adheres to the intestine, peritoneum, and omentum, and is almost caseous. Necrotic liquefaction ruptures into the abdominal cavity, intestinal cavity, or is discharged outward through the abdominal wall. After the disease is cured, scattered or extensive calcification can be seen.
