Chiari I Malformation-associated syringomyelia (CM) and idiopathic syringomyelia (IS) are often confused together. They require different diagnostic approach and treatment modalities; it is important to distinguish between the two. We aimed to evaluate the radiological and morphologic characteristics of CM and IS in adult and pediatric patients in Pakistani population.
Our retrospective case series was conducted at the Department of Radiology, Punjab Institute of Neurosciences assessing the operated cases of CM and IS cases from January 2022 to December 2023. Preoperative morphologic and radiological data was collected for adult and pediatric patients.
Out of 16 patients, 75% were adults and four were children. Twelve patients were male. The mean age of adult patients at presentation was 30.50 ± 9.20 years. There were nine cases of Chiari I Malformation and seven cases of idiopathic syringomyelia. Craniocervical junction (CCJ) was the most common site of syrinx formation in adults (41.66%) in both Chiari I and IS groups. The mean size of syrinx in adults in IS was 7.842 ± 1.93 and in CM was 4.740 ± 0.45. Mean size of syrinx in children was 4.84 ± 0.48 mm. Moniliform shape was the most common form of syrinx in patients in both CM and IS groups.
In the Pakistani population, this study focuses on the radiological characteristics of idiopathic syringomyelia (IS) and Chiari I Malformation (CM), both of which commonly exhibit a moniliform syrinx. The craniocervical junction was frequently involved in CM, but IS exhibited a wider, bigger syrinx. Accurate diagnosis as well as treatment depend on imaging.
Chiari I型畸形相关脊髓空洞症（CM）和特发性脊髓空洞症（IS）常被混淆。它们需要不同的诊断方法和治疗方式；区分两者很重要。我们旨在评估巴基斯坦人群中成人和儿童患者CM和IS的放射学及形态学特征。
我们的回顾性病例系列研究在旁遮普神经科学研究所放射科进行，评估2022年1月至2023年12月期间CM和IS的手术病例。收集了成人和儿童患者的术前形态学和放射学数据。
16例患者中，75%为成人，4例为儿童。12例为男性。成人患者就诊时的平均年龄为30.50±9.20岁。有9例Chiari I型畸形和7例特发性脊髓空洞症。在Chiari I型畸形和IS组中，颅颈交界区（CCJ）是成人脊髓空洞形成最常见的部位（41.66%）。IS组成人脊髓空洞的平均大小为7.842±1.93，CM组为4.740±0.45。儿童脊髓空洞的平均大小为4.84±0.48mm。串珠状是CM和IS组患者中脊髓空洞最常见的形式。
在巴基斯坦人群中，本研究关注特发性脊髓空洞症（IS）和Chiari I型畸形（CM）的放射学特征，两者通常都表现为串珠状脊髓空洞。颅颈交界区在CM中常受累，但IS表现为更宽、更大的脊髓空洞。准确的诊断和治疗依赖于影像学检查。
