BACKGROUND
Prompt diagnosis and early treatment institution are important in intraventricular neurocysticercosis (IVNCC) as compared to the parenchymal or racemose form because it is associated with a poorer patient prognosis. Intraventricular neurocysticercosis is often missed on CT scan or conventional cranial magnetic resonance imaging because of similar density or signal intensity of cysticercus lesion with cerebrospinal fluid.Thestudy aims to evaluate the added value of 3D-DRIVE and SWI MRI sequences in isolated intraventricular cysticercosis with acute neurological presentation.
METHODS AND MATERIALS
This retrospective study was carried out on diagnosed 10 patients with isolated intraventricular neurocysticercosis (IVNCC) presented to a tertiary care hospital with an acute onset of symptoms or acute neurological deficit between June 2019 to May 2021. Relevant neurological examination, CSF analysis, a serological test of neurocysticercosis and MRI scan of the brain were performed.
RESULT
Tenpatients of isolated intraventricular neurocysticercosis (3 males and 7 females) having 3 pediatric and 7 adults were included in this study sample.The common neurological complications of the isolated intraventricular neurocysticercosis in this study are observed as obstructive hydrocephalus in 8(80%) patients and ependymitis in 7(70%) patients. IVNCC with distinctly visualized scolex (visibility score 2) identified in 2(20%) patients in T2WI, 8 (80%) patients in 3D-DRIVE and 3(30%) patients in SWI sequences. The cyst wall of IVNCC was distinctly visualized (visibility score 2) in 1(10%) patient in T2WI, 8(80%) patients in 3D-DRIVE and 6(60%) patients in SWI sequence.
CONCLUSION
Heavily T2-weighted steady-state and SWI sequences should be added to routine MRI sequences that helps to identify IVNCC and should be used in patients with unexplained hydrocephalus, especially in endemic regions of Neurocysticercosis
背景
与实质型或葡萄状型相比，脑室内神经囊尾蚴病（IVNCC）的及时诊断和早期治疗机构非常重要，因为它与患者预后较差有关。由于囊尾蚴病变与脑脊液的密度或信号强度相似，脑室内神经囊尾蚴病在CT扫描或传统头颅磁共振成像上常被漏诊。本研究旨在评估3D-DRIVE和SWI MRI序列在具有急性神经表现的孤立性脑室内囊尾蚴病中的附加价值。
方法和材料
本回顾性研究对2019年6月至2021年5月期间在一家三级护理医院就诊的10例诊断为孤立性脑室内神经囊尾蚴病（IVNCC）且有急性症状发作或急性神经功能缺损的患者进行。进行了相关的神经学检查、脑脊液分析、神经囊尾蚴病的血清学检测和脑部MRI扫描。
结果
本研究样本包括10例孤立性脑室内神经囊尾蚴病患者（3例男性和7例女性），其中3例儿童和7例成人。本研究中孤立性脑室内神经囊尾蚴病的常见神经并发症为8例（8０%）患者出现梗阻性脑积水，7例（70%）患者出现室管膜炎。在T2WI序列中，2例（20%）患者的IVNCC可见明显的头节（可见度评分2），在3D-DRIVE序列中有8例（80%）患者可见，在SWI序列中有3例（30%）患者可见。在T2WI序列中，1例（10%）患者的IVNCC囊壁可见明显显示（可见度评分2），在3D-DRIVE序列中有8例（80%）患者可见，在SWI序列中有6例（60%）患者可见。
结论
应将重T2加权稳态和SWI序列添加到常规MRI序列中，这有助于识别IVNCC，并且应用于不明原因脑积水的患者，尤其是在神经囊尾蚴病的流行地区。
