| 中文摘要 | 腦下垂體腫瘤所造成的視野缺損多為單側或雙側之顳側視半盲。我們在 此介紹一病例,以同側視半育視野缺損表現之腦下垂體腫瘤。該三十三歲女性患 者除了在視野方面的表徵外,無論是臨床表現,內科之生化檢驗數據,頭部X光 及頭部之電腦斷層掃描,均顯現出為一典型之腦下垂體腫瘤。於外科之開顱手術 中,可見一巨大腦下垂體腫瘤延伸至右側顳葉;這就可解釋本病例在視野方面所 表現之特異性。 |
| 英文摘要 | Pituitary tumor usually induces bitemporalhemianopsia. We present a female patient with clinical manifestation of pituitary tumor but visualfield reveals homonymous hemianopsia. Skull X-rayof the patient showed ballooning of sella turcica with lesion in dorsum sella and brain CT discloseda big tumor occupying the pituitary fossa with extension into right parasella area. The patient recieved craniotomy with partial excision of the tumor mass, and the patliology proved the growth hormone releasing chromophobe adenoma. The etiology of this different visual field defect is due to the lesion expanding posteriorly and compressing fibers of the optic tract, which correspond to the demonstration of brain CT and the intra operative finding. |
