One characteristic of WM is the production of an abnormal high amount of IgM and hyper viscosity syndrome. The MW gets worse, symptoms such as fatigue, weight loss, night sweats, fever, recurrent infections and swollen lymph nodes develop in patients who have a known history of MGUS. In this clinical case, our patient without history of MGUS, presents for the first time for medical observation only for ascites and the presence of an interportocaval lymph node package. An atypical presentation of the disease that makes us reflect on the difficulty of making a diagnosis in the elderly patient and on pathogenetic hypotheses of ascites not yet explored.Case Presentation: Seventy-three-year-old patient, hospitalized for the onset of ascites with sloping edema, diffuse left pulmonary opacification. At the ultrasound check, cava and portal vessels patent and of regular caliber, however with inversion of flow in correspondence with the right branch and of the door to the hilum, with a subdiaphragmatic retrocaval focus with a maximum diameter of about 3 cm, which cannot be better viewed. CT scan of the abdomen with confirmation of the presence of an interportocaval lymph node package. After evidence of the electrophoretic protein picture of a double component, probably monoclonal with positive urinary immunofixation for free K chains. IgM dosage equal to 2190 mg. Serum immunofixation practice that confirms the diagnosis of type B lymphoproliferative syndrome as per Waldenstrom’s disease, confirmed by bone marrow aspiration with morphological and flow cytometric study. Immediately begin chemotherapy with Bendamustine 120 mg. After 4 weeks of therapy with the reduction of IgM values, the patient no longer presented ascites.Conclusion: This case has an unusual presentation of this disease and we could shed a new light on the possible pathogenesis of portal hypertension in Waldenstrom’disease.Keywords: ascites, portal hypertension, Waldenstrom’s disease, elderly
