Plain-English summary
A 3-year-old female Basset Hound was brought to the vet because she had a fever and was limping for two months. During the exam, the vet found a small mass in her abdomen that looked like a swollen lymph node on an ultrasound. Tests showed that she had an infection caused by a type of bacteria called Mycobacterium smegmatis, which was affecting her liver and lymph nodes. Unfortunately, the prognosis was poor, and the decision was made to euthanize her.

Abstract
A 3-year-old female Basset Hound was examined because of fever and lameness of 2 months' duration. Physical examination revealed a small cranial abdominal mass, which had an ultrasonographic appearance of a large abdominal lymph node. Cytologic examination of an ultrasound-guided fine-needle aspirate of the mass revealed a few macrophages that contained numerous linear unstained structures consistent with mycobacteria. Intracellular acid-fast bacilli were identified in an aspirate that was stained with modified Ziehl-Neelsen. Exploratory laparotomy revealed wide-spread abdominal lymphadenopathy. Histologic examination of hepatic and lymph node biopsy specimens revealed chronic granulomatous hepatitis and lymphadenitis. Acid-fast organisms isolated after bacteriologic culturing of a mesenteric lymph node specimen were identified as Mycobacterium smegmatis. Because the prognosis was poor, the dog was euthanatized.
