CTA Head There is no relevant literature to support the use of CTA head in the initial evaluation of children with suspected periorbital or orbital infection. CTV Head There is no relevant literature to support the use of CTV head in the initial evaluation of children with suspected periorbital or orbital infection. It may be useful in evaluation of cases in which cavernous sinus thrombosis is suspected as a complication of orbital cellulitis. MRA Head There is no relevant literature to support the use of MRA head in the initial evaluation of children with suspected periorbital or orbital infection. MRI Head MRI of the head with and without IV contrast can be complementary to CT scan and may be considered if a more detailed assessment of intraorbital spread of infection is clinically warranted. It may be especially considered for cases in which there is clinical or CT-based suspicion for intracranial complications [46]. MRI Orbits MRI of the orbits and head with and without IV contrast can be complementary to CT scan and may be considered if a more detailed assessment of intraorbital spread of infection is clinically warranted. It may be especially considered for cases in which there is clinical or CT-based suspicion for intracranial complications [46]. MRV Head There is no relevant literature to support the use of MRV head in the initial evaluation of children with suspected periorbital or orbital infection. Suspected superior orbital vein or cavernous sinus thrombosis (as a complication of orbital cellulitis) may be better evaluated with MRI of brain and orbits with IV contrast rather than MRV. Variant 8: Child. Leukocoria or suspected intraocular mass. Initial imaging. Leukocoria is defined as abnormal white reflection from the retina of the eye (compared with normal red reflection) and can be related to abnormalities of the lens, vitreous, or retina.
