Congenital intramedullary spinal ependymal cyst

Area of Science:

• Pediatric Neurosurgery
• Spinal Cord Pathology
• Congenital Malformations

Background:

• Congenital intramedullary ependymal cysts are exceedingly rare spinal cord tumors.
• Association with spinal dysraphism, such as kyphoscoliosis and rachidian malformations, is uncommon.
• This case represents the fifth reported instance in the medical literature.

Purpose of the Study:

• To report a rare case of congenital intramedullary ependymal cyst in a pediatric patient.
• To discuss the diagnostic challenges and histological differentiation from other intradural cysts.
• To review the relevant literature on intramedullary ependymal cysts.

Main Methods:

• Diagnostic workup included myelography, which suggested an intramedullary lesion.
• Surgical intervention involved total enucleation of the cyst.
• Histopathological examination was performed for definitive diagnosis and differentiation.

Main Results:

• A congenital intramedullary ependymal cyst of the dorsal cord was identified in a 7-year-old boy.
• The cyst was associated with kyphoscoliosis and dorsal spine malformations.
• Complete surgical removal was achieved due to the cyst's posterior location and clear cleavage plane.

Conclusions:

• Congenital intramedullary ependymal cysts, though rare, can be successfully treated with complete surgical excision.
• Accurate histological differentiation is crucial for appropriate management and prognosis.
• This case contributes to the limited understanding of these spinal cord anomalies.
