Hemorrhagic Vestibular Schwannoma after Minor Head Injury

輕微頭部外傷後聽神經腫瘤出血

摘要


出血性聽神經腫瘤很少發生,通常是腫瘤內脆弱的血管破裂所導致,症狀多為突發性頭痛及聽力喪失。我們報導了一輕微頭部外傷後造成出血性聽神經腫瘤的案例,其出血的原因可能是外傷時牽扯到腫瘤內的血管所導致,對於較大的腫瘤,目前治療方式還是建議手術,並建議避免頭部外傷。

It is rare for hemorrhage within a vestibular schwannoma to occur, which is caused by the rupture of fragile intratumoral vessels. When this type of hemorrhage does take place, acute onset of headache and hearing loss are frequently experienced. We report a patient with intratumoral hemorrhage inside a vestibular schwannoma after mild head injury, and discuss the possible mechanism such as traction on the tumor vasculature during the injury. Excision is the recommend treatment for large tumor. We also advise patients with vestibular schwannoma to make every effort to avoid head injuries.
