Endoscopic evaluation of Spirocerca lupi infection in a non-descript dog: A case report

A non-descript dog about three years was presented with the history of vomiting for three weeks with yellow colour vomitus. Lateral survey radiography of thorax revealed elevated thoracic trachea with enlarged mediastenal lymph node and nodular lesion underneath at the level of third intercostal space. On endoscopic examination, the oesophageal mucosa was pale pink in colour with two glistening nodules in the proximal thoracic oesophagus. Histopathological examination of oesophageal nodular biopsy revealed fibrous tissue infiltrated with inflammatory cells. Coprological examination demonstrated presence of ova of Spirocerca lupi worms and the condition was diagnosed as a case of Spirocerca lupi infection. The dog was treated with doramectin, rabeprazole and ondansetron and became asymptomatic within three weeks of treatment.
