title: Two cases with giant pseudo-aneurysm of vertebral artery secondary to shrapnel injury.
abstract: BACKGROUND
  Due to their locations, vertebral arteries (VA) are structures that are rarely injured after traumas. Formation of vertebral pseudo-aneurysm (PA) because of pieces of shrapnel is also rare. It causes clinical findings like cervical mass after the injury CASES PRESENTATION: Two Syrian 12- and 17-year-old male patients were admitted to the Department of Ear, Nose and Throat with the complaint of swelling in the left lower cervical region. In their USG examination which was ordered to investigate the cervical lesion, a lesion consistent with PA which shows a prominently thick wall structure due to circumferential thrombus formation and fibrotic tissue, chaotic flow, and ying-yang appearance in the centrally located cavity of the lesion in a color Doppler examination was detected. Later, multi-detector computed tomography angiography (MDCTA) was planned to demonstrate pseudo-aneurysms (PAs).
  
  
  CONCLUSIONS
  Because there was no report on the development of giant pseudo-aneurysms secondary to shrapnel injury to date and because we thought these cases are demonstrative, we found the cases suitable for presenting as case reports.
