ABSTRACT
BACKGROUND: Listeriosis is a rare disease in cats with naturally occurring cases usually being identified in individual animals. Listerial mesenteric lymphadenitis has not been described previously in cats. OBJECTIVES: To describe the clinical and histological features of listerial mesenteric lymphadenitis in cats as well as treatment outcome. ANIMALS: Listerial mesenteric lymphadenitis was confirmed in 3 cats by histology, immunohistochemistry, and bacterial culture. RESULTS: The affected cats were young to middle aged and were examined for various clinical signs. On both palpation and abdominal ultrasound examination, all cats had marked mesenteric lymphadenomegaly. Survival was prolonged in all 3 cases. Two of the 3 cats were fed a raw meat-based diet before they developed clinical illness. CONCLUSIONS AND CLINICAL IMPORTANCE: Lymphadenitis caused by listeriosis has a protracted time course and should be a differential diagnosis for abdominal lymphadenopathy in young to middle-aged cats. Feeding of a raw meat-based diet may be a contributing factor for development of listeriosis in cats.

Mesenteric lymphadenitis constitutes a frequent cause for abdominal pain and may manifest acute abdominal symptoms. Very often, it is difficult to achieve a differential diagnosis as there are many diseases that can generate mesenteric lymphadenopathy. Many times, it is impossible to determine the diagnosis of the disease that has triggered mesenteric lymphadenopathy even after surgical intervention with biopsy. The failure in determining the precise cause of the mesenteric lymphadenoapathy, as well as its unresponsiveness to conservative treatments increases the difficulty in the management of this disease very much. In this paper we have reviewed the diseases that can trigger mesenteric lymphadenitis in detail, with reference to our experience. To the best of our knowledge, this is the most extensive review on this theme in current specific literature. The case reported by us, with a history of mesenteric adenitis, splenic and ganglionic abscesses, vasculitis skin nodules, pseudotumoral ileal stenosis and remission-recurrence pattern over 25 years, has raised extremely difficult problems of differential diagnosis. Its enlistment as a Crohn's disease, vasculitis or aseptic abscess syndrome seems unsatisfactory. The analysis of the data in this case can raise the legitimacy of the question: should we recognize and define a new entity?

The problem of diagnostics acute mesenteric a lymphadenitis is actual and till now not solved. Use laparoscopy techniques in differential diagnostics of acute surgical diseases of an abdominal cavity has opened new prospects. Acute mesenteric the lymphadenitis in clinical practice can be surveyed as a polyetiological syndrome of the enlarged mesenteric/lymph nodes. If acute mesenteric the lymphadenitis is implication of infectious diseases medicament therapy is spent. A biopsy of a lymph node with the subsequent histological research at an infectious disease not informative. At verification of tubercular, oncology and autoimmune diseases is the basic method of diagnostics.

Cryptococcal infection of intraabdominal organs or tissues is extremely rare. Herein we report a child with mesenteric cryptococcal lymphadenitis who presented with an acute abdomen misdiagnosed as acute appendicitis. Definitive diagnosis was established with 2nd look and lymph node biopsy. Clinicians should remember that cryptococcal infection of mesenteric lymph nodes may rarely mimic an acute abdomen and cause delay in diagnosis.

Infection by Yersinia pseudotuberculosis has become of increasing pathological importance. This report describes the case of a 12-year-old female with mesenteric lymphadenitis due to Yersinia pseudotuberculosis. The patient presented with fever, abdominal pain, and a palpable right abdominal mass. Abdominal ultrasonic imaging and computerized axial tomography (CT) revealed a mass. An exploratory laparotomy was performed, followed by appendectomy and mesenteric lymph node biopsy. The diagnosis of Yersinia infection was confirmed by serology and bacterial culture of the biopsy material. This condition should be considered in patients with a right lower abdominal mass and symptoms similar to those of appendicitis.
