Spontaneous Retropharyngeal Hematoma: Diagnosis by MR Imaging

Alberto Muñoza, Nancy J. Fischbeina, Joaquin de Vergasa, Jose Crespoa and Jose Alvarez-Vincenta

a From the Departments of Radiology (A.M.) and Otorhinolaryngology (J.V., J.C., J.A.V.), Hospital Universitario, Madrid, Spain, and the Department of Radiology (A.M., N.F.), University of California, San Francisco, San Francisco, CA.

Summary: Spontaneous retropharyngeal hematoma is an uncommon entity that is difficult to diagnose and may progress rapidly to airway obstruction. We report a case of a 53-year-old man with acute onset of retropharyngeal pain, dysphonia, and dysphagia after vomiting. On CT, a nonspecific retropharyngeal collection was seen. MR imaging demonstrated blood products, suggesting a diagnosis of retropharyngeal hematoma, and the patient was managed conservatively. MR imaging allowed specific diagnosis of a rare condition that is otherwise difficult to diagnose without surgical intervention.
