A 20-year-old lady presented with neck swelling with difficulty in swallowing and trismus. On clinical examination there was a diffuse swelling involving the neck. Lateral radiograph of the neck was taken which showed straightening of the cervical spines with 10-12 mm widening of the prevertebral space (figure 1). Computed Tomography scan of the neck showed hypodense fluid collection in the retropharyngeal space from C4-C8. Ultrasonography of the neck showed thrombosis in bilateral internal jugular vein. An eccentric soft tissue plaque was seen along the mid internal jugular vein measuring 1.8 mm. USG Doppler showed partial thrombosis of bilateral IGV showing ulcerated plaque with luminal narrowing approximately 30% on right side and a soft tissue plaque causing luminal narrowing of up to 25% on left side. Sputum for acid fast bacilli and Mantoux test were negative. Patient was taken up for cervical exploration and around 20-25 cc of pus was drained by putting an incision over maximum bulge over posterior pharyngeal wall. CLINICAL DIAGNOSIS Retropharyngeal Abscess DIFFERENTIAL DIAGNOSIS Other deep neck space infections (like prevertebral abscess, Ludwig’s angina), foreign body in aerodigestive tract, pneumonia, mediastinitis, epidural abscess, oral cavity infections, epiglottitis, pharyngitis.
