description In the Buenos Aires Province, a significant number of annual cattle deaths occur for various reasons, with only a small percentage of farms conducting diagnostic confirmations. Among the primary causes of acute death, magnesium deficiency and certain infectious diseases such as bacillary hemoglobinuria and anthrax are noteworthy. Nonetheless, there are secondary factors, such as hydrallantois, which can occasionally be associated with acute death. Hydrallantois refers to the abnormal accumulation of fluid within the allantoic sac. While this condition is more commonly observed in cattle, it remains a rare occurrence in pregnancy. The initial case, which came to the attention of the Veterinary Diagnostic Service at the Faculty of Veterinary Sciences, Universidad Nacional del Centro de la Provincia de Buenos Aires (FCV-UNCPBA) in July 2018, involved a necropsy and diagnostic procedures carried out on an Aberdeen Angus cow from a herd that had witnessed four deaths within a month. The second case emerged in June 2018 when an adult Aberdeen Angus cow was identified through anamnesis and clinical examination by a private veterinarian. Unfortunately, the cow was found dead 18 days after the clinical diagnosis, prompting a post-mortem examination. During necropsy in both cases, a striking finding was the presence of severe hydrallantois in the pregnant uterus, containing more than 100 liters of allantoic fluid. Microscopically, detachment of the fetal trophectoderm was observed with edema and mineralization, evident through an area of connective tissue within the placentomes. This report aims to outline various clinical presentations and highlight the macroscopic and microscopic observations from two cases of hydrallantois in cows. It is vital to emphasize the importance of recognizing this rare pathology as a possible differential diagnosis of acute death in cows, as a consequence of cardiorespiratory failure resulting from thoracic pressure.

En la Provincia de Buenos Aires, un número significativo de muertes anuales de ganado ocurre por diversas razones, y solo un pequeño porcentaje de establecimientos realiza confirmaciones diagnósticas. Entre las principales causas de muerte aguda se destacan la deficiencia de magnesio y determinadas enfermedades infecciosas como la hemoglobinuria bacilar y el ántrax. Sin embargo, existen causas secundarias, como el hidroalantoides, que en ocasiones pueden asociarse con muerte aguda. El hidroalantoides se refiere a la acumulación anormal de líquido dentro del saco alantoideo. Si bien esta afección se observa con mayor frecuencia en el ganado vacuno, su ocurrencia sigue siendo poco común durante la gestación. El caso inicial, que llegó a conocimiento del Servicio de Diagnóstico Veterinario de la Facultad de Ciencias Veterinarias de la Universidad Nacional del Centro de la Provincia de Buenos Aires (FCV-UNCPBA) en julio de 2018, involucró una necropsia y procedimientos diagnósticos realizados en una vaca Aberdeen Angus de un rodeo que había presenciado cuatro muertes en un mes. El segundo caso surgió en junio de 2018, cuando un veterinario privado identificó a una vaca Aberdeen Angus adulta mediante anamnesis y el examen clínico. Desafortunadamente, la vaca fue encontrada muerta 18 días después del diagnóstico clínico, lo que obligó a realizar un examen post mortem. Durante la necropsia en ambos casos, el hallazgo principal fue la presencia de hidroalantoides severo en el útero gestante, que contenía más de 100 litros de líquido alantoideo. Microscópicamente, se observó el desprendimiento del trofoectodermo fetal con edema y mineralización, evidente a través de un área de tejido conectivo dentro de los placentomas. Este informe tiene como objetivo describir varias presentaciones clínicas y resaltar las observaciones macroscópicas y microscópicas de dos casos de hidroalantoides en vacas. Es vital enfatizar la importancia de reconocer esta patología poco común como posible diagnóstico diferencial de muerte aguda en vacas, como consecuencia de una insuficiencia cardiorrespiratoria resultante de la presión torácica.
