[Mesenteric lymphadenopathy in Yersinia enterocolitica infection].
We report a case of previously undiagnosed Yersinia enterocolitica infection in a 46-year old woman. She consulted her physician because of continual weight loss and physical lassitude. A leucocytosis was found. Sonography revealed an excessive enlargement of abdominal lymph nodes. A malignant lymphoma was suspected and the patient underwent a staging by CT. There the disease was limited on mesenteric and retroperitoneal lymph nodes. Bone marrow biopsy and CT-guided lymph node biopsy did not confirm a systemic lymphatic disease. The patient did not undergo a special therapy. After six months, CT showed a clear regression of enlarged lymph nodes. Finally, a previous Yersinia enterocolitica infection of immunotype 03 could be proved serologically. At this time, the patient had no complaints. Diagnostic and differential diagnosis of benign abdominal lymph node enlargement are discussed based on literature.
