Abstract

Introduction: Enterogenous cysts are rare developmental malformations located predominantly in the spinal canal. We report here a very rare case with enterogenous cyst, containing nevus cells pathologically.Case
Presentation: This was a case of a 48-year-old man complaining of gradually developing numbness in the right upper and lower limbs for two months. Magnetic resonance imaging revealed a noncontrast-enhancing mass lesion at the C2-C4 level, that are low signal intensity on T1-weighted imaging, high signal intensity on T2-weighted imaging. Computed tomography myelogram showed a positive meniscus sign with no contrast enhancement. We performed subtotal resection of the cyst via posterior approach. Histopathology showed mucin-producing simple columnar or cuboidal ciliated cells, which was consistent with an enterogenous cyst. Interestingly, nevus cells were observed in the stroma surrounding the cyst epithelium. The patient’s numbness and hypoesthesia improved immediately, and had no recurrence for two years.Discussion: This is the third case describing enterogenous cyst, containing nevus cells, and these findings suggested enterogenous cysts are endodermal in origin.Conclusion: We report a very rare case of an enterogenous cyst containing nevus cells pathologically. Our findings suggest that enterogenous cysts are endodermal in origin.
