Posttraumatic subepicranial varix.

Two cases of subepicranial varix following injury are reported. They were associated with depressed skull fractures. Subepicranial varix is a rare and benign scalp mass, and should be differentiated from vascular anomalies of the scalp and cystic masses of the scalp communicating with the cerebrospinal space. The relationship between subepicranial varix and sinus pericranii is discussed.
