Post-Traumatic Aneurysms of the Superficial Temporal Artery
A 21-year-old male presented with two painless, compressible, pulsatile nodules on the left temple that had spontaneously appeared 1 week previously. The patient‘s history revealed that he was a semi-professional Muay Thai boxer and usually trained without a helmet. The physical examination was unremarkable except for the two temporal nodules. Investigations for possible vasculitis, including laboratory parameters, yielded normal results. Duplex ultrasound showed two true aneurysms of the left superficial temporal artery (2.8 × 4.6 mm and 3.0 × 4.8 mm) with normal, arterial perfusion, whereas the literature usually describes pseudoaneurysms following trauma. In this particular case, repetitive shearing and crushing forces possibly triggered a pathological process that promoted the development of the true aneurysms. Although surgical removal of the aneurysms would normally be indicated, the patient declined surgical resection. Therefore, we advised him to wear a suitable helmet during sports in order to avoid further trauma to the head.
