In January 2000, a 7-year-old female Pumi was presented to the Kecskemét Veterinary Hospital, Kecskemét, Hungary with a history of dysphagia, vomiting, and retching after feeding for some days. Plain radiography of the thorax revealed a grey circumscribed area in the caudal region of the oesophagus between the heart base and diaphragm, while contrast radiography demonstrated stricture and partial obstruction in the oesophagus. Although the dog showed progressive weight loss and permanent vomiting for two months, the owner declined further treatment and the patient was euthanized in March 2000. At necropsy, a subspherical nodule measuring 4.5x3x3 cm was found in the caudal part of oesophagus. Deeper cavity of the nodule contained seven adults of Spirocerca lupi embedded in yellow inflammatory debris. In January 2001, a 2.5-year-old male rural German shepherd dog from Kecel region (Bács-Kiskun County, Hungary) was admitted to the Small Animal Clinic of Veterinary Faculty, Szent István University, Budapest, Hungary. Signs of returning mucous vomiting, retching, dyspnoe and weight loss progressed over approximately 7 to 8 months prior to admission to the clinic. Parasitological examination of a faecal sample of the dog by Sheather's sugar flotation method revealed numerous eggs of S. lupi and Alaria alata. In the caudal end of the oesophagus, gastro-oesophagoscopy demonstrated a number of nodules covered with intact mucous membrane. The dog was treated against spirocercosis with ivermectin at a dosage of 200 μg/kg sc. 3 times at 14-day intervals, and against alariosis with praziquantel at a dosage of 5 mg/kg p.os for two consecutive days. After the treatment, clinical signs resolved and no eggs in the faeces could be detected.
