Paediatrics: Mesenteric Adenitis: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Mesenteric Adenitis🎧 A clear, high-yield breakdown of this paediatric cause of abdominal pain – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• Mesenteric adenitis is inflammation of the abdominal (mesenteric) lymph nodes, typically affecting children and often mimicking appendicitis.📌 Causes & Risk Factors• Usually viral infections (e.g. adenovirus, enterovirus)• Occasionally bacterial (e.g. Yersinia enterocolitica)• Often follows a recent upper respiratory tract or gastrointestinal infection• Most common in children and young adolescentsMnemonic: “VIRAL nodes mimic APPENDIX pain”📌 Pathophysiology• Infection triggers the immune system, leading to swelling/inflammation of the mesenteric lymph nodes• This local immune response causes right lower quadrant (RIF) pain📌 Symptoms• Acute abdominal pain (often RIF)• Fever, nausea, sometimes vomiting or diarrhoea• Recent viral illness (e.g. cold, sore throat) is a key clue• May have palpable abdominal tendernessMemory tip: Pain + recent cold = mesenteric adenitis📌 Differential Diagnosis• Appendicitis (always rule out!)• Inflammatory bowel disease (IBD), especially Crohn’s• Urinary tract infection• Ovarian torsion (in girls)• Gastroenteritis📌 Diagnosis• Primarily clinical, supported by: – Blood tests (often normal in mesenteric adenitis; raised markers suggest appendicitis) – Abdominal ultrasound (shows enlarged mesenteric nodes, rules out appendicitis) – Urine dipstick (excludes UTI) – Pregnancy test in relevant cases• CT rarely used (to avoid radiation in children)📌 Management• Supportive care: – Paracetamol/ibuprofen for pain – Fluids and rest – Reassurance for child and parents• Antibiotics NOT usually needed (unless specific bacterial cause is confirmed)📌 Complications• Rare, but can include: – Abscess formation – (Very rarely) Peritonitis – Misdiagnosis leading to unnecessary surgery📌 Prognosis• Excellent – almost always self-limiting, resolves in a few weeks, with no long-term problems📎 More MSRA Resources for Mesenteric Adenitis📝 Revision Notes: https://www.passthemsra.com/topic/mesenteric-adenitis-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/mesenteric-adenitis-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/mesenteric-adenitis-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/mesenteric-adenitis-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/paediatrics-for-the-msra/#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #Paediatrics #MesentericAdenitis
