摘要:

垂体转移瘤是一种少见的从全身各部位恶性肿瘤转移至垂体所致的颅内恶性肿瘤。常见垂体转移瘤为多血供,而少血供转移瘤临床罕见,影像学表现与垂体瘤较难鉴别,容易误诊。现报道1例经病理确诊的鞍区少血供肺转移低分化腺癌,其主要诊断线索包括:(1)恶性肿瘤病史;(2)鞍内存在正常垂体结构;(3)病变呈等T1等T2信号影。

Abstract:

Pituitary metastasis is a rare intracranial malignant tumor originated from other malignant tumors at other parts of the body.Pituitary metastases are typically hypervascular,while hypovascular pituitary metastasis is rare.Radiologically,hypovascular pituitary metastasis is difficult to be distinguished from pituitary adenoma.This article reports one case of pathologically confirmed hypovascular pituitary metastasis,with the main diagnostic clues including history of malignant tumor,presence of normal pituitary in the intrasellar region,and isointensity on T1 and T2 sequence.

Key words: pituitary, metastases, magnetic resonance imaging, diagnosis
