Objective: To describe the magnetic resonance imaging (MRI) manifestations of intraspinal enterogenous cysts, and to provide reliable information for further clinical management.
Methods: The MRI findings and related clinical data of 6 patients with surgically and pathologically confirmed intraspinal enterogenous cysts were retrospectively studied.
Results: Among the 6 patients, most enterogenous cysts were oval or fusiform in shape with well-defined margins. Five cysts were located in the subdural extramedullary space and one cyst was located intramedullary. The signals were hypo-or iso-intensity on T1W images and hyperintensity on T2W images. On the postcontrast images, five showed no enhancement, and one was enhanced peripherally.
Conclusion: The MRI findings of intraspinal enterogenous cysts are specific and the correct preoperative diagnosis may be obtained by integrating MRI findings with clinical data.
