Bilateral hypoplasia of the soft palate in a foal.

This study presents a case of a foal suffering from bilateral hypoplasia of the soft palate and aspiration pneumonia. The findings revealed abnormalities including a shortened soft palate and a uvula-like mass, and also confirmed a palatal defect and moderate severity aspiration pneumonia with no other congenital abnormalities present.

Background and Case Presentation

• The research revolves around a Standardbred foal that suffered from bilateral hypoplasia of the soft palate, leading to aspiration pneumonia. The condition was abnormal and noticeable as the filly exhibited signs of illthrift, dyspnoea, coughing, and bilateral nasal discharge.
• Upon clinical examination, abnormal sounds were heard over all lung fields and the cervical trachea. Further, an endoscopic examination revealed a visibly shortened soft palate with a uvula-like mass protruding into the nasopharynx. Mucopurulent material was also detected in the trachea.

Investigation and Findings

• Specimens from a tracheal wash were forwarded for cytology, culture, and sensitivity testing. The test results pointed to a septic inflammatory process.
• Radiographic examination of the foal’s thorax revealed patchy consolidation areas and air bronchograms. Ultimately, owing to the severity of its condition, the animal had to be euthanized.

Necropsy and Final Diagnosis

• The necropsy confirmed the presence of a palatal defect consistent with the earlier observations of a shortened soft palate. Furthermore, aspiration pneumonia that was of moderate severity was also confirmed.
• Significantly, the necropsy didn’t uncover any other congenital abnormalities, in effect ruling out any multiple congenital anomalies syndrome or systemic issues that may have contributed to or complicated the condition.
