The salted pretzel sign is an uncommon sign of the presence of numerous small (<3 mm) calcific foci in the distal branches of a cerebral artery on non-contrast CT head that represent a shower of calcified cerebral emboli 1. Cerebral calcified emboli may be the initial manifestation of significant vascular or cardiac disease 2 and prompts cardiovascular workup.
