INTRODUCTION: Acquired Chiari malformation and related syringomyelia have been beforehand described following lumbar puncture/drainage, lumboperitoneal shunts, and spontaneous cerebrospinal fluid leakage. Along with these etiologies, space-occupying lesions equivalent to meningiomas, epidermoid cysts, medulloblastomas, and arachnoid cysts are uncommon causes of acquired Chiari malformation and syringomyelia. We report a uncommon case of colloid cyst with hydrocephalus inflicting secondary Chiari malformation with syringomyelia.
CASE REPORT: A 58-year-old woman introduced with neck ache and problem in strolling and numbness of all four limbs of 1-year period. Diagnostics with magnetic resonance imaging of the pinnacle and the cervical backbone had been finished within the referring hospital. The sufferers was then referred with the analysis of colloid cyst with hydrocephalus and Chiari malformation 1 with cervicodorsal syringomyelia. She underwent colloid cyst excision by the transcallosal strategy. Postoperatively the affected person confirmed enchancment in her symptomatology. Magnetic resonance imaging of the mind and cervical backbone at 6 months’ follow-up confirmed resolved Chiari malformation and resolving syrinx.
CONCLUSIONS: Colloid cyst with hydrocephalus is a uncommon reason for secondary Chiari malformation with syringomyelia. Surgical administration of the underlying lesion improves acquired Chiari malformation and related syringomyelia.
