  • Cerebrovascular diseases and intracranial tumors pose significant risks to military pilots, emphasizing the need for thorough screening and early intervention to prevent inflight incapacitation.
  • The study investigates the types of intracranial diseases and medical imaging findings in military pilots (cadets) undergoing physical exams for transfer to high performance aircraft, aiming to improve aeromedical support.
  • Of 554 pilots examined, 36 were found with abnormal MRI results, displaying conditions such as arachnoid cysts, small aneurysms, and other issues that disqualified them from flying high-performance aircraft.

We present a rare case of an intraparenchymal chordoma in the brain stem of a 69-year-old male with a history of multiple chordoma recurrences. Chordomas are uncommon tumors that originate from notochordal remnants, with intraparenchymal presentations in the brain stem being particularly rare. A 69-year-old male with a history of clival chordoma three years after primary endoscopic resection and adjuvant proton-beam radiotherapy and a recurrence one year postoperatively for which he underwent a second surgery, presented with severe headaches, weakness, diaphoresis, and difficulty ambulating.
