Body wall mass incidentally found and diagnosed as undifferentiated neoplasia by FNA in an 11 year old MN Siberian Husky

An 11-year-old MN Siberian Husky was presented for evaluation of anorexia and increased sleeping. The only significant abnormality on physical examination was pyrexia (104). Blood chemistry showed low BUN, hypocalcaemia, and hypokalemia. Abdominal and thoracic radiographs were within normal limits. Interim therapy was I.V. fluid therapy, antibiotics, and supportive care with further evaluation being abdominal ultrasound.

Sonographic Differential Diagnosis

Body wall mass – likely sarcoma or similar neoplasia. Appears resectable if isolated to this region.

Image Interpretation

The body wall appeared infiltrated by a hypoechoic mass destroying fascial planes and normal curvilinear body wall muscle patterns. The peritoneum did not appear affected.

DX

Undifferentiated neoplasia-bodywall mass

Outcome

Further laboratory testing showed high total protein, hyperbilirubinemia, elevated AST activity, decreased albumin/globulin ratio, hyperglobulinemia, and a normal CBC. The patient was humanely euthanized.

Comments

 
 

The abdominal organs were unremarkable in this patient. At times the sonographer simply has the task of defining something abnormal that deviates from normal curvilinear patterns…even in the body wall. Exemplary in this case is a body wall mass that is easily sampled. The world of clinical sonography takes turns like this in the diagnostic thought process based on the resourcefulness of the clinican. It doesnt matter how we get there but it matters that we get the diagnosis efficiently and hopefully in the moment that we have the opportunity to do so. Seek and you shall find.

 

Clinical Differential Diagnosis

Infectious disease (bacterial/fungal), immune mediated disease, neoplasia.

Sampling

US-guided FNA. Fine needle aspirate cytology from the body wall mass was consistent with undifferentiated neoplasia.
