Abstract

Cerebral hemorrhage is one of the most common causes of dysphagia. In many cases, dysphagia gets better once the acute phase has passed. Structural lesions such as thyromegaly, cervical hyperostosis, congenital web, Zenker's diverticulum, neoplasm, radiation fibrosis, and retropharyngeal abscess must be considered as other causes of dysphagia as well. Retropharyngeal abscess seldom occur in adults and if it does so, a search for a prior dental procedure, trauma, head and neck infection is needed. The symptoms may include neck pain, dysphagia, sore throat, and in rare cases, dyspnea accompanied by stridor. We present a case and discuss a patient who had dysphagia and neck pain after a cerebral hemorrhage. Testing revealed a retropharyngeal abscess. The symptoms were successfully treated after the administration of antibiotics.

  Fig. 1 Video fluoroscopic swallowing study. (A) On lateral radiographic image taken prior to administration of antibiotics, residual barium is visualized at the pyriform sinus and vallecular sinus of the pharynx (thick arrows). Extensive edema in the retropharyngeal space (RS) and some aspirated barium in the airway is seen (thin arrow). (B) A decreased amount of residual barium was identified at pyriform sinus and vallecular sinus following treatment with antibiotics for a period of 8 weeks (thick arrows), and there were no signs of aspiration (thin arrow).

  Fig. 2 The laryngoscopic finding. The features show edema of the posterior pharyngeal wall (PW) and a large amount of mucous secretion (MS).

  Fig. 3 A CT of the neck with contras. Extensive edema of the retropharyngeal space (RS) and a focal patchy enhancing lesion (*) near osseous lesions (arrow) are identified.

  Fig. 4 A contrast cervical spine MRI. (A) Contrast-enhanced sagital T1-weighted fat suppression image (before administrating antibiotics). Alteration of signal intensity at medulla of C2-C4 cervical spine level (*). A well enhanced soft tissue lesion that suggests a retropharyngeal abscess at prevertebral space is identified (RS). (B) A well enhanced soft tissue lesion was improved following treatment with antibiotics for 8 weeks (arrow).
