The morphology of the cavum septi pellucidi (CSP), cavum Vergae (CV), and cavum veli interpositi (CVI) has been infrequently explored with neuroimaging. The aim of the present study was to delineate these cavities using magnetic resonance (MR) imaging.
A total of 71 patients were enrolled in the present study. Following initial examinations with conventional MR sequences, constructive interference in steady-state (CISS) sequence was performed in the coronal and sagittal sections for 60 and 11 patients, respectively.
The coronal CISS images at the level of the aqueduct showed two distinct morphologies of the CV roof, one formed by the fornices with varying degrees of conjugation and the other formed by the corpus callosum with completely separated fornices. Appearance of the CSP was classified into four distinct types. Furthermore, the CVI presented two distinct appearances.
Typically, the CSP, CV, and CVI present with asymptomatic conditions with morphological variabilities. Visualization of the CSP, CV, and CVI using the CISS sequences may be useful when managing lesions affecting these cavities.
利用神经影像学对透明隔腔(CSP)、韦尔加腔(CV)和中间帆腔(CVI)的形态进行研究的情况并不常见。本研究的目的是使用磁共振(MR)成像来描绘这些腔隙。
本研究共纳入71例患者。在采用传统MR序列进行初步检查后,分别对60例和11例患者在冠状面和矢状面进行了稳态构成干扰(CISS)序列检查。
导水管水平的冠状面CISS图像显示CV顶有两种不同形态,一种由不同程度结合的穹窿形成,另一种由胼胝体形成且穹窿完全分离。CSP的外观分为四种不同类型。此外,CVI呈现出两种不同外观。
通常,CSP、CV和CVI表现为无症状状态且形态各异。在处理影响这些腔隙的病变时,使用CISS序列对CSP、CV和CVI进行可视化可能会有帮助。
