Renal hemangiosarcoma in a 5-year-old intact male German Shepherd: Our Case Of the Month March 2015
Traumatic event or emerging hemangiosarcoma? Note the diagnostic power of a recheck sonogram. Giving the benefit of the doubt is best for the patient but rechecking for regression or progression of the lesion will enhance your gut feeling for the underlying pathological truth. Check out this presentation imaged by Andi Parkison RDMS of Intrapet Imaging, Baltimore, Maryland, USA and how a prudent follow-up was key to the true diagnosis in this case despite the "traumatic' history. A special thanks to Hickory Veterinary Hospital, Dr. Melissa Adams and Dr. Bob Silcox.
A 5-year-old male German shepherd was presented for evaluation of progressive pain, lethargy, anorexia, and hunched back following an episode of abdominal trauma - tried to jump over a large hole and hit his abdomen on the edge of the hole.
Sonographic Differential Diagnosis
Hemangiosarcoma is a rapidly expanding neoplastic process that can often present with a history of suspected "trauma." Given that both traumatic lesions and HSA can cause hematoma formation HSA should be considered especially in predisposed breeds. Traumatic clot should begin to resolve progressively but logically HSA will progress and expand as it did in this case.
