Cystadenocarcinoma arising from ovary in a three year old doberman bitch / Cistoadenocarcinoma derivado del ovario en una perra doberman de tres años

A three- year- old Doberman was presented with complaint of lethargy and weight- loss. Physical examination revealed a mass in the right abdomen. Laboratory abnormalities included anaemia, azotaemia and metabolic acidosis. Sonogram of the mass was an anaechoic area surrounded by hypoechoic tissue. The mass was located between the right kidney and ovary and showed papillary and tubular pattern of cystadenocarcinoma. Nephroureterectomy and ovariohysterectomy was performed; however bitch was euthanized owing to poor improvement, while necropsy of the left kidney revealed an end-stage kidney. It was concluded that the cystadenocarcinoma must have arisen secondary to a primary ovarian adenocarcinoma through stromal invasion.

Se presentó una perra doberman de tres años de edad aquejada de letargo y pérdida de peso. El examen físico reveló una masa en el abdomen derecho. El examen de laboratorio mostró anormalidades que incluyeron anemia, azotemia y acidosis metabólica. La ecografía de la masa mostró un área anecoica rodeada por tejido hipoecoico. La masa se localizó entre el riñón derecho y ovario y mostró el patrón papilar y tubular del cistoadenocarcinoma. Se realizó la nefroureterectomía y ovariohisterectomía, sin embargo la perra fue sacrificada debido a la falta de mejoría, donde la autopsia del riñón izquierdo reveló un riñón en etapa terminal. Se concluyó que el cistoadenocarcinoma debió haber surgido secundario a un adenocarcinoma primario de ovario a través de la invasión del estroma.

Splenic metastases in ovarian carcinoma

We report two cases of ovarian carcinoma with splenic metastases detected by ultrasound and discuss their sonographic appearances. The importance of routinely including this organ during staging and follow-up studies in ovarian carcinoma using diagnostic imaging methods is emphasized
