case_images: (a-e) Contrast enhanced CT scan images at the level of naso/oropharynx: axial (a), sagittal (c) and coronal (b) and (d) revealing an abscess within right retropharyngeal and parapharyngeal spaces seen as a low density lesion with thin rim of peripheral enhancement (black arrowheads on b). Also note the massive displacement of the trachea ((white arrow in d) and lateral sinus thrombosis on e) seen as filling defects in the sinus (white arrows).

case_images: A CT scan was done, revealing a 27 mm x 47 mm x 42 mm parapharyngeal/paravertebral cystic mass obliterating the oropharyngeal airway and acute left LST (Figure 1); the latter confirmed on MRI (Figure 2).
case_images: (a-d) (a) Coronal T2 weighted MR scan showing the neck abscess as a contrast-enhancing irregular lesion (white arrow), with evident tracheal displacement (black arrow showing the endotracheal tube). Note the displacement of neck arteries on the arteriogram (b) and on the venogram (c), left lateral sinus thrombosis (black arrow) seen as absence of contrast in the sinus as well as the jugular vein (white arrow). On the repeat MR venogram (d) done on the 14th day, note the recanalization of the left lateral sinus (black arrowhead) and internal jugular vein (white arrowhead).

case_images: A CT scan was done, revealing a 27 mm x 47 mm x 42 mm parapharyngeal/paravertebral cystic mass obliterating the oropharyngeal airway and acute left LST (Figure 1); the latter confirmed on MRI (Figure 2). A repeat MR venogram (Figure 2) done at the end of his 14 day stay in the ward showed partial re-cannulation in the sinuses.
