Pseudoascites in the clinical setting: avoiding unwarranted and futile paracenteses

Ascites is diagnosed on physical exam by findings of abdominal distension, bulging flanks, shifting dullness and a prominent fluid wave. However, as the following cases demonstrate, these signs may also be positive in pseudoascites due to thick layers of adipose tissue in the abdomen. A history of recent food binging and a lack of a prolonged prothrombin time should raise the index of suspicion for pseudoascites in a patient with a protuberant abdomen. In light of equivocal physical signs, physicians may employ ultrasonography to prevent patients with pseudoascites from suffering multiple futile attempts at paracentesis.
