Oral and Pharyngeal Diverticula: A Rare Case of Dysphagia and Diagnostic Challenges.

This report describes the case of a 62-year-old male patient in Saudi Arabia who developed a diverticular pouch in his oral cavity. Diverticula are rare conditions that appear as protrusions or pouches within the digestive tract's inner lining. The condition can occur in different parts of the digestive system, but the colon is the most affected part. As part of the patient's symptoms, he presented with dysphagia, weight loss, and globus sensations. Multiple diagnostic tests, including ultrasound, computerized tomography (CT), and magnetic resonance imaging (MRI), did not identify the diverticula. Barium and upper gastrointestinal studies were the diagnostic tests that provided accurate diagnoses where several diverticula were discovered during the videofluoroscopic swallow study (VFSS) and fiberoptic endoscopic evaluation of swallowing (FEES). Surgical intervention was recommended by the multidisciplinary team; however, the patient rejected this treatment option. This report highlights the necessity for instrumental swallowing diagnostic evaluation in the workup of the infrequent etiologies of dysphagia and suggests a gap in the current knowledge, prompting further studies on the etiology, incidence, and optimum management of upper gastrointestinal (GI) tract diverticular disease.
