Preauricular cysts, pits (as shown below), fissures, and sinuses are benign congenital malformations of the preauricular soft tissues first described by Van Heusinger in 1864. Preauricular pits or Color-Doppler Flow Imaging (CDFI) demonstrated continuity with the main trunk of superficial temporal artery (STA) and displayed a turbulent flow inside the lesion. A computed tomography (CT) angiography was also performed, confirming that the preauricular mass was a saccular aneurysm of the main trunk of STA, measuring 1.4 cm in diameter.
