Tumours growing in the sella turcica are mostly pituitary adenomas. We describe a rare case of primary intrasellar schwannoma with intratumoral bleeding. A 38-year-old man presented with headache in association with bilateral supratemporal quadrantopsia. MRI showed an intrasellar mixed signal mass lesion with suprasellar extension. The majority of the pituitary hormones were normal. He was diagnosed as non-functional pituitary adenoma with pituitary apoplexy. Subtotal resection was achieved eventually via an endoscopic transnasal trans-sphenoidal approach. The histopathologic diagnosis was schwannoma. It is the first intrasellar schwannoma with intratumoral hemorrhage in literature to date. It implied that the primary intrasellar schwannoma has potential risk of intratumoral bleeding, which should be considered in the differential diagnoses of sellar lesions.
鞍内生长的肿瘤多为垂体腺瘤。我们描述了一例罕见的鞍内神经鞘瘤伴瘤内出血。一名 38 岁男性因头痛伴双侧颞上象限偏盲就诊。MRI 显示鞍内混杂信号肿块伴鞍上延伸。大多数垂体激素正常。他被诊断为伴有垂体卒中的无功能垂体腺瘤。最终通过经鼻蝶内镜手术实现了大部分肿瘤切除术。组织病理学诊断为神经鞘瘤。这是迄今为止文献中首例鞍内神经鞘瘤伴瘤内出血。这表明原发性鞍内神经鞘瘤有潜在的瘤内出血风险，在鞍区病变的鉴别诊断中应考虑到这一点。
