Abstract :

Extradural spinal arachnoid cysts (SEACs) are rare lesions, which may become symptomatic due to mass effect. Multiple cysts are even rarer of which few are reported to date. To the best of our knowledge only 18 cases of multiple extradural arachnoid cysts have been reported so far¹.

We experienced 2 cases of SEACs over a period of 5 years. 42 years old female patient presented with back ache and progressive paraparesis. Magnetic resonance imaging of spine revealed dorsal arachnoid cyst. 12-year-old female presented with back ache progressive paraparesis. Magnetic resonance imaging of spine revealed multiple spinal extradural arachnoid cysts located in dorso-lumbar spine causing mass effect. The patients underwent surgery for the excision of the cysts and closure of dural defects.

In the present paper the authors review the literature and discuss the clinical and neuroimaging characteristics, and surgical management of spinal extradural arachnoid cysts.
