Abstract:
External carotid artery aneurysms are rare, and mycotic involvement is even more uncommon. We present a 65-year-old man who developed a rapidly enlarging mycotic superficial temporal artery aneurysm 2 years after blunt trauma. Initial imaging showed only a minor temporal bone fracture. During a 2023 hospitalization for small bowel obstruction complicated by ileus, intubation, and empiric antibiotics, magnetic resonance imaging revealed a 1.85-cm superficial temporal artery aneurysm, which enlarged to 2.69 cm during a later admission. He presented with rapid expansion and skin breakdown and underwent urgent open excision, followed by culture-directed oral antibiotics for 2 weeks, resulting in complete resolution.
