Orbital abscess: a) Axial ceCT image in a soft tissue window showing severe right sided proptosis with the entire right eyeball lying anterior to the interzygomatic line (dotted line). b) Coronal image in the same patient showing a large intraorbital fluid collection with a thick enhancing rim (*) and sharp angles in relation to the orbital wall (long arrow). These imaging findings are indicative of an orbital abscess. The floor of the frontal sinus shows a bony dehiscence (short arrow)
