EP 481: Lymphadenitis in Pets – Causes, Diagnosis & Clinical Approach | Pet Care Partners Podcast

Welcome to Episode 481 of the Pet Care Partners Podcast, where we tackle lymphadenitis—the inflammation of lymph nodes that can signal infection, immune dysfunction, or neoplasia. This episode is tailored for veterinary students preparing for the NAVLE and clinicians seeking diagnostic clarity in cases of peripheral or generalized lymphadenopathy. We break down the types of lymphadenitis (suppurative, granulomatous, eosinophilic, pyogranulomatous), their most common etiologies in cats and dogs, and the stepwise approach to diagnostic testing, including FNA cytology, lymph node biopsy, culture, and imaging. 💡 In This Episode You'll Learn: • The difference between reactive lymphadenopathy vs true lymphadenitis • Common causes: bacterial, fungal, viral, protozoal, and immune-mediated • What to expect on cytology: neutrophilic vs granulomatous inflammation • When to biopsy vs aspirate, and how to interpret culture and PCR results • How to manage cases caused by pathogens like Bartonella, Toxoplasma, or Blastomyces • Red flags for lymphoma masquerading as lymphadenitis 🎯 Best For: • Veterinary students studying clinical pathology and infectious disease • Practicing DVMs evaluating lymphadenopathy in general or referral practice • Internal medicine and emergency clinicians • Educators seeking clinical case examples of swollen lymph nodes in pets #Lymphadenitis #Lymphadenopathy #VeterinaryPodcast #VetMed #PetCarePartners #NAVLEPrep #VeterinaryStudents #VetClinPath #SmallAnimalMedicine #InfectiousDiseaseInPets #VeterinaryCytology #FNA #ReactiveLymphNodes #FelineMedicine #CanineMedicine #VeterinaryEducation #Episode481 #VeterinaryDiagnosis #GranulomatousLymphadenitis #LymphNodeBiopsy #PetHealth #InternalMedicineVet
