Fluid collection in the retropharyngeal space (RPS), including retropharyngeal abscess and several non-infectious diseases, appears in various diseases that should be treated in different clinical departments. Since emergency conditions causing neck pain can demonstrate this finding on CT or MRI, radiologists are required to differentiate these diseases to facilitate proper treatment. The purpose of this exhibit is: 1. To review the normal anatomy of the RPS 2. To review diseases that demonstrate fluid collection in the RPS in children and adults

1. Normal anatomy of the RPS 2. Fluid collection in the RPS in children a) Infectious conditions; retropharyngeal abscess, cervical lymphadenitis, foreign body ingestion b) Malignancies; lymphoma, leukemia c) Kawasaki disease d) Congenital disease; pyriform sinus cyst 3. Fluid collection in the RPS in adults a) Infectious conditions (ENT); retropharyngeal abscess, cellulitis, foreign body ingestion b) Infectious conditions (orthopedics); osteomyelitis c) Non-infectious conditions (ENT); lymphangioma, laryngeal edema d) Non-infectious conditions (orthopedics); calcific tendinitis of the longus colli muscle, compression fracture e) Malignancies and tumor-related conditions 4. Indications for imaging modalities regarding treatment options
