Abstract

A sellar spine is a rare osseous projection from the dorsum sellae, resulting in variable compression of sellar and suprasellar structures and varied clinical presentations. CT is the diagnostic modality of choice, while variable signal intensity on MRI may mimic a pituitary microadenoma. A patient presented with hypoprolactinaemia and puerperal alactogenesis due to a sellar spine diagnosed on CT Brain. Neurosurgical and endocrine review and pituitary MRI were recommended with subsequent loss to follow-up.

摘要

鞍结节是一种罕见的从鞍背发出的骨性突起，可导致鞍内和鞍上结构的不同程度受压，并产生多样的临床表现。CT是首选的诊断方式，而MRI上的可变信号强度可能会被误诊为垂体微腺瘤。一名因脑部CT诊断为鞍结节的患者出现了低催乳素血症和产后无乳的症状。建议进行神经外科和内分泌科会诊以及垂体MRI检查，但患者随后失访。
