Massive haematoma formation associated with proximal popliteal artery haemangioendothelioma in a dog


Bass, D; Grest, P; Hagen, R; Makara, M; Quante, S; Rohrer-Bley, C (2011). Massive haematoma formation associated with proximal popliteal artery haemangioendothelioma in a dog. Journal of Small Animal Practice, 52(11):612-615.

Abstract

A mixed breed dog presented with diffuse unilateral hind limb swelling, which ultrasound and cytol- ogy confirmed to be caused by severe haematoma formation. Multi-detector computed tomography (MDCT) angiography allowed distinct visualisation of an anomalous segment of the proximal popliteal artery, the presumed origin of the self-sustaining haematoma. Histopathology classified the malformed vessel as a haemangioendothelioma, a neoplasia of intermediate malignancy. Considering this as dif- ferential diagnosis to a neoplastic vascular alteration of high malignancy (such as haemangiosarcoma) might alter choice of treatment in future cases with similar clinical and imaging findings.
