Advanced cerebrospinal fluid flow MRI findings of aqueductal stenosis caused by web
Background The aqueductal web (AW) is one of the causes of aqueductus stenosis (AS). Recent advances in Magnetic resonance (MR) imaging have enabled us to better reveal the cerebrospinal fluid (CSF) flow dynamics and aqueductal anatomy. Purpose The aim of this study is to evaluate the CSF flow dynam...

| description | Background
The aqueductal web (AW) is one of the causes of aqueductus stenosis (AS). Recent advances in Magnetic resonance (MR) imaging have enabled us to better reveal the cerebrospinal fluid (CSF) flow dynamics and aqueductal anatomy.
Purpose
The aim of this study is to evaluate the CSF flow dynamics of patients with AW with phase contrast Magnetic resonance imaging (MRI) and compare them with the imaging findings.
Materials and Methods
We evaluated 23 patients under 65‐year‐old age. On constructive interference in steady‐state (T2 CISS) images, the width of prepontine cistern (PPC) and the width of Sylvian aqueduct (SA) were measured. Localization and number of webs were evaluated. The existence of flow at the aqueduct and the presence of spontaneous third ventriculostomy (STV) were evaluated on sagittal Sampling Perfection with Application optimized Contrast (SPACE) sequences.
Results
Of the 23 patients included in the study, 11 were male and 12 were female. The mean age was 34.02 (0.5–64). A total of 31 AWs were detected in 23 patients.
Six of 23 patients (26.1%) had STV and 17 of those not. Four of 23 patients (17.4%) had aqueductal flow on SPACE sequences. The PPC distance was significantly wider in patients with STV (median: 6.7–4.5, interquartile range (IQR): 1.35, p = 0.004). In the cases where artifact secondary to flow is observed in SPACE sequences in aqueduct, the Evan index (EI) was significantly lower (median: 0.2955–0.3900, IQR: 0.03–0.14, p |

Conclusion
In patients with a low EI, there may be flow in the SA even if there is a web. In patients with a wide PPC distance, it is necessary to consider the presence of STV and evaluate the presence of flow with the SPACE sequences.
The aqueductal web is one of the causes of aqueductus stenosis. Patients with a low Evans index may have flow in the Sylvian aqueduct even if there is a web.
