Overview
In cases of deep abscess or occult abscess, and in cases of orbital cellulitis, a CT scan can be quite useful in the diagnosis and in differentiating pre or post septal cellulitis. A CT image shows a thick rim of enhancement enclosing a collection of fluid indicative of an abscess; with the surrounding tissue showing swelling and enhancement consistent with cellulitis. CT scan is the diagnostic modality of choice in pre vs post septal cellulitis. Imaging shows enhancement anterior to the septum with diffuse soft tissue thickening in pre septal cellulitis. Post septal or orbital cellulitis may show edema of the extraocular muscles, intraorbital abscess, inflammatory stranding of fat, and poor definition of the orbital planes.
CT scan
In cases of deep abscess or occult abscess, and in cases of orbital cellulitis, a CT scan can be quite useful in the diagnosis and in differentiating pre or post septal cellulitis. A CT image shows a thick rim of enhancement enclosing a collection of fluid indicative of an abscess; with the surrounding tissue showing swelling and enhancement consistent with cellulitis. CT scan is the diagnostic modality of choice in pre vs post septal cellulitis. Imaging shows enhancement anterior to the septum with diffuse soft tissue thickening in pre septal cellulitis. Post septal or orbital cellulitis may show edema of the extraocular muscles, intraorbital abscess, inflammatory stranding of fat, and poor definition of the orbital planes. [1] [2] [3]
