Hyperacute unilateral contrast-induced parotiditis during cerebral angiography

Song J Kim et al. Radiol Case Rep. .

Abstract

An uncommon complication of iodinated contrast administration is the development of bilateral sialadenitis. We report a unique case of hyperacute unilateral parotiditis during diagnostic cerebral angiography of the external carotid artery, which mimicked possible iatrogenic vascular event associated with cerebral endovascular procedures. Discussion includes the differential diagnosis, diagnostic studies, and treatments for this unusual condition.

Keywords: Cerebral angiography; Iodine contrast; Sialadenitis.
