Infarct/ischemia	Transcortical, ischemia, encephalomalacia
Intracranial mass	Known and unknown diagnosis; including intraparenchymal, sellar, pineal, and so forth
Mass effect	Herniation, midline shift, diffuse edema, sulcal effacement, ventricular effacement
Microvascular	Chronic ischemic microvascular white matter changes, lacunar infarctions
Pneumocephalus	Intraparenchymal, extra-axial, intraventricular
Postprocedural	Craniotomy, craniectomy, ventricular catheters/drains, drains, cataract surgery, lines
Sinus	Acute or chronic paranasal or mastoid disease
Soft-tissue/osseous	Any abnormalities pertaining to these structures
	Exception: postsurgical or related to the sinuses
Ventricular caliber	Hydrocephalus, ex vacuo dilation, ventriculomegaly, prominent
	Exception: effacement caused by mass effect
Volume loss	Cortical atrophy/volume loss, both diffuse and focal
	Exception: ventriculomegaly likely secondary to volume loss
Other	Malformations, abnormal calcification, dural thickening, artifacts, and so forth
