An increase in the number of cross-sectional studies over time has caused an increase in the number of reported incidental findings, or incidentalomas. While some incidental findings are clinically insignificant, there are many significant findings that fail to be mentioned in the radiology report. It is important to always look for incidental findings as they are common, and they may change patient management. We describe a numerous array of incidentalomas on CT head/neck to recognize their prevalence and clinical significance.

Educational Goals / Teaching Points
Familiarize residents with the different incidental findings seen on CT head and neck. Realizing the importance of comprehensive search patterns to look for such incidental findings. Have a basic background knowledge regarding these incidental findings, their significance and correct reporting and interpretation of these findings.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
We present numerous cases of incidental in contrast and non-contrast enhanced CT head and neck findings that we encountered at our institution. These cases are often overlooked as the indication for most of these cases are either trauma or stroke. Some of these incidental findings are significant and can change management, treatment, and outcomes for patients and should be routinely reported. The cases we presented here have incidental vascular (venous and arterial), osseous, soft tissues and normal variants, Cases include superior ophthalmic vein thrombosis, fenestration of the basilar artery, triple ACA, clivus fracture, retained tooth in the maxillary sinus, Fibromuscular Dysplasia of the ICAs, dural sinus thrombosis tumors of the external auditory canal, and nasal septum lipoma.

It is important to include and search for incidental findings on CT head and neck, as they can be clinically significant and change patient care and outcomes.
