Ascites with no fluid in Morison’s pouch?

Abstract

<jats:title>Abstract</jats:title><jats:p>Omental cysts are the least common cystic lesions of the abdomen. Large intraabdominal cysts can mimic ascites. The incidence of 1 in 20000 pediatric hospital admissions makes them hard to diagnose. We report a three year-old boy with accidentally discovered intraperitoneal fluid collection on ultrasonography. The patient was scheduled for operative treatment with working diagnosis of ascites, but finding of no fluid in Morison’s pouch brought to massive cystic intraabdominal lesion as differential diagnosis. The cyst was emptied; altered parts of the greater omentum were completely excised. Final pathology confirmed lymphangioma. Explorative laparotomy led to correct diagnosis and proper surgical treatment.</jats:p>

An Omental Lymphatic Malformation Mimicking Ascites in a 2‐Year‐Old Boy

“…They typically present as asymptomatic abdominal distension, but can also present with pain, vomiting, or obstructive symptoms (3). Large omental and intra‐abdominal lymphatic malformations may mimic ascites on imaging and physical examination, with evidence of fluid throughout the abdomen and fluid wave on examination (4). Occasionally, septations may be seen within the “ascites” hinting at the possibility of an underlying cystic process (5).…”
