Abstract

In a group of 69 patients with pituitary tumours, 12 were found to have evidence of intratumoral haemorrhage on MRI, characterized by high signal intensity on short TR/TE sequences. This was verified in all but 1 patient. The majority of the bleedings occurred in macroadenomas. Five (42%) were prolactinomas and 4 (33%) were non-functioning adenomas. There were 2 GH- and 1 ACTH-secreting tumours. All 5 patients with prolactinomas were on bromocriptine medication. Two of the patients had a clinical picture of pituitary apoplexy. The haemorrhage was not large enough to prompt surgery in any of the patients. However, surgical verification of the diagnosis was obtained in 5 cases, while 6 patients were examined with follow-up MRI.

摘要

在一组69例垂体肿瘤患者中，12例在MRI上显示有瘤内出血迹象，其特征为在短TR/TE序列上呈高信号强度。除1例患者外，其余均得到证实。大多数出血发生在大腺瘤中。5例（42%）为泌乳素瘤，4例（33%）为无功能腺瘤。有2例生长激素分泌型肿瘤和1例促肾上腺皮质激素分泌型肿瘤。所有5例泌乳素瘤患者均在服用溴隐亭。2例患者有垂体卒中的临床表现。出血均未大到足以促使任何患者进行手术。然而，5例患者进行了手术诊断验证，6例患者接受了MRI随访检查。
