Haemothorax and haematuria in a Dutch Warmblood horse due to metastasised anaplastic sarcoma

Abstract

Summary:A 5-year old Dutch Warmblood gelding was presented with bilateral epistaxis, dyspnoea, a stiff gait, a reluctance to move and a wide-base stance, lethargy, anorexia and a muscular defence. Ultrasonography revealed marked pleural effusion on both left and right sides of the thorax and 7 litres of haemorrhagic fluid was drained after placement of a thoracic catheter. Cystoscopy was performed when the horse was showing haematuria several days later and the haemorrhagic fluid was seen originating from the right ureter. Subsequent ultrasonography of the kidneys revealed a mass in the right kidney, from which a tentative diagnosis of a primary tumour of the kidney with metastasis to the thorax was made. Anaplastic sarcoma in both kidneys, lungs and heart of unknown primary origin was diagnosed post mortem resulting in haemothorax and haematuria.Keywords: haemothorax / haeloturia / anaplastic sarcoma / metastasis / kidney tumour / oncology Citation: de Heer N., Compagnie E., Bergmann W., ter Braake F., Kranenburg L.
