A 4-month-old male entire French bulldog was presented for the investigation of acute left thoracic limb lameness. Computed tomography (CT) revealed a right-sided humeral intracondylar fissure (HIF) and a left-sided medial humeral condylar fracture which was managed by open reduction and internal fixation. Follow-up CT at 36 days after surgery revealed healing of the condylar fracture and partial resolution of the HIF, which was radiographically unapparent on further CT images 105 days thereafter (at 220 days of life). To the best of the authors' knowledge, this is the first reported case of spontaneous resolution of a HIF beyond the normal age of reported humeral condyle ossification center closure.
A 12‐year‐old mixed‐breed dog was presented for a follow‐up examination after ablation of an auricular mast cell tumour. An abdominal ultrasound and computed tomography were performed and an irregular, ill‐defined and partially mineralised lesion was observed around the caudal duodenal flexure without evidence of metastasis. The cytologic examination was highly suggestive of a granular cell tumour. Partial surgical ablation with histological and immunohistochemical examination of the lesion confirmed the diagnosis. According to our review of the literature, this is the first report documenting an abdominal granular cell tumour in a dog.
OBJECTIVE
To describe a treatment for a mandibular fracture in a guinea pig (Cavia porcellus).
ANIMAL
A 6-month-old sexually intact male guinea pig referred for a 24-hour history of hyporexia.
CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES
Physical examination showed lateral displacement of the incisors and inflammation and crepitation during mandible lateralization. Imaging tests revealed a minimally displaced complete oblique fracture of the left mandible with fracture of the left mandibular first premolar tooth and incisor tooth.
TREATMENT AND OUTCOME
Conservative treatment was established by placing a chin sling (CS) to immobilize the jaw and a nasogastric tube for nutritional support. Imaging tests repeated 3 weeks later showed initial callus formation, and the conservative treatment was discontinued. Follow-up examinations showed appetite and progressive weight gain. Five months later, the clinical crown of the left mandibular incisor was absent and a resorptive lesion on the left mandibular first premolar tooth was detected. Complete ossification of the fracture without premolar and moler teeth elongation was observed on control imaging tests. Ten months after initial examination, the patient was reportedly healthy with no signs of pain or dental disease.
CLINICAL RELEVANCE
Jaw fracture treatments in guinea pigs are poorly described in the literature. Surgical treatment can be challenging in this species due to its skull and dental anatomy. Although CS was originally employed to increase the congruency of premolar and molar teeth after coronal reduction, this device yielded satisfactory results as a noninvasive, inexpensive treatment of a mandibular fracture in this guinea pig. Alopecia on the back of the head was the only undesired adverse effect associated with the CS.
Background
Oesophageal pneumatosis (OP) is defined as the presence of gas within the oesophageal wall. The description of this condition in veterinary medicine is currently lacking. The pathogenesis of alimentary tract pneumatosis remains unclear. Current literature describes that access of gas into the oesophageal wall may occur by one or a combination of the following mechanisms: mucosal disruption, increased intra or extra‐luminal pressure or dissection of gas from an extra‐oesophageal source.
Objectives
The aim of this multi‐centric case series was to describe the computed tomography (CT) findings of OP in dogs.
Methods
Three adult dogs were included. One dog presented with gastrointestinal signs and general malaise while the other two presented with spontaneous facial and cervical subcutaneous emphysema.
Results
CT revealed different degrees of intramural gas along the oesophageal wall in all cases. The first dog was diagnosed with emphysematous gastritis based on the presence of gastric pneumatosis paired with compatible clinicopathological and endoscopic findings. This dog was successfully treated with antibiotics. The remaining two dogs were diagnosed with spontaneous pneumomediastinum and required no surgical or medical treatment.
Conclusions
In all cases with OP, there was concurrent gastric pneumatosis. Gas extensively and circumferentially distributed with a banded shape along the oesophageal wall was present in patients with presumed mural gas dissection because of pneumomediastinum. Conversely, a focal and mild amount of mural gas with a tubular shape was identified in the distal segment of the oesophagus in the patient with emphysematous gastritis.
