Nonspecific mesenteric lymphadenitis.Inflammation of lymph nodes in the mesentery.
Medical necessity for the evaluation and management of nonspecific mesenteric lymphadenitis is established by the patient's presenting signs and symptoms, especially abdominal pain.The need for imaging studies to confirm the diagnosis and rule out other conditions must also be justified based on the clinical picture. If treatment beyond supportive care is required, the medical necessity for such interventions should be clearly documented.
Diagnosis and treatment of nonspecific mesenteric lymphadenitis typically falls under the purview of general practitioners, family medicine physicians, internists, or gastroenterologists.In cases of complications like abscess formation, surgeons may be involved.
In simple words: Inflammation of the lymph nodes in the mesentery, the membrane that connects the intestines to the abdominal wall.
Nonspecific mesenteric lymphadenitis. Mesenteric lymphadenitis (acute)(chronic)
Example 1: A 10-year-old boy presents with abdominal pain, fever, and nausea.Physical examination reveals tenderness in the right lower quadrant.Imaging studies show enlarged lymph nodes in the mesentery. The diagnosis of nonspecific mesenteric lymphadenitis is made., A 25-year-old woman experiences sharp abdominal pain, vomiting, and low-grade fever. After undergoing a CT scan, she is diagnosed with nonspecific mesenteric lymphadenitis., A patient presents with chronic abdominal pain and bloating. After extensive testing, a diagnosis of chronic mesenteric lymphadenitis is confirmed.
Documentation should include details of the patient's presenting symptoms (e.g., abdominal pain, fever, nausea, vomiting), physical examination findings (e.g., tenderness in the abdomen), and imaging results (e.g., enlarged mesenteric lymph nodes). Any relevant laboratory findings should also be documented.If there are associated symptoms or suspected underlying causes, these should be noted as well.
