Case Study
Round cell neoplasia suspect in a 5-year-old MN Greyhound dog
Sonographic Differential Diagnosis
Suspect infiltrative disease or fungal disease such as pythiosis. Round cell neoplasia
Image Interpretation
Epigastric lymphadenopathy was present and significantly enlarged with loss of structural detail as well. A large amount of reactive omentum was noted around the upper gastrointestinal tract and pancreas. The mid to distal small intestine was unremarkable. The liver presented increased portal markings and thickened gallbladder with some nodular changes primarily in the region of the porta hepatis and right medial liver. The hepatic veins were not dilated. A moderate amount of abdominal free fluid was noted, which was echogenic. A large amount of pleural effusion , echogenic, was also noted with variable areas of lung consolidation. A thickened myocardium was noted. The contractility appeared adequate. Upper gastrointestinal infiltrative pattern with pleural effusion and ascites. Aggressive upper gastrointestinal mesenteric root lymphadenopathy.
DX
Suspect round cell neoplasia .
Outcome
The patient was started on immunotherapy protocol.
Comments
Abdominocentesis and pleurocentesis would be ideal in this patient with culture and sensitivity if the lymph node aspiration is not diagnostic. Guarded to poor prognosis.
Clinical Differential Diagnosis
GI tract pathology – obstruction (foreign body, intussusception), neoplasia, IBD, infectious (bacterial, viral, fungal, helminths), toxins, dietary. Peritonitis. Pancreatic pathology (pancreatitis); Acute liver pathology (toxins, infectious, trauma)
Sampling
FNA of lymph nodes were performed and inconclusive.. They are suspicious for round cell neoplasia. No structures consistent with Pythium were noted. However, the blood titers were suggestive for pythiosis. There was no evidence of complication noted post FNA.
