Lumbosacral neurenteric cyst with associated tethered cord in an adult.
Spinal neurenteric cysts are rare congenital lesions of endodermal origin that lead to spinal cord compression or tethering. These cysts are usually lined by mucus-secreting epithelium resembling that of the gastrointestinal tract. A 31-year-old man presented with low back and bilateral limb pain of three-year duration. Magnetic resonance imaging (MRI) revealed an intradural extramedullary heterogeneous mass lesion at L4 - L5 disc level causing severe compression and displacement of terminal portion of conus medullaris to the left side. Additionally, tethered cord, syringohydromyelia and spina bifida were present. He had also polysyndactyly on the left foot. The patient underwent laminoplasty and partial excision of the lesion through a posterior approach. Neurosurgical exploration revealed a large intradural, extramedullary solid lesion with cystic component, compressing the spinal cord. Histopathology confirmed a neurenteric cyst with mucin-producing cuboidal or columnar epithelium lining the cystic cavity. Clinical suspicion is important for an early diagnosis, and their early preplanned surgical removal should be the goal of treatment, which leads to a better outcome. This case is reported in view of rare congenital abnormality in an adult with peculiar presentation.
