Ingestión vagal por absceso en linfonodulos mediastínicos.

Abstract

Vagal indigestion is characterized by a vagus nerve injury, this may be partial or total along its course. The present case describes a vagal indigestion due to an abscess in mediastinal lymph nodes in a 10-year-old Holstein cow that entered the UNESP large animal clinic with a history of recurrent tympanysm due to possible dislocation of the abomasum. Physical examination showed bilateral abdominal distension, anorexia, anuria and absence of defecation. After performing paraclinical examinations such as hemoleucogram, blood chemistry, ruminal fluid study, haemogasometry and ultrasound, increased fibrinogen, segmented lymphocytes and neutrophils, high urea and low creatinine and signs of metabolic acidosis were found. diagnosed vagal indigestion of nonspecific origin. The animal was euthanized due to the poor prognosis of the syndrome and at necropsy the presence of abscesses in mediastinal lymph nodes was determined, which was corroborated microscopically evidencing a pyogranuloma of unknown origin.
