Posttraumatic leptomeningeal cyst capsule as a cost-free autograft for its repair: case illustrated technical reports

The surgical treatment of traumatic leptomeningeal cyst (LMC) is repair of the dural defect with or without cranioplasty. The dural substitutes used are either autografts (which may not be enough) or artificial grafts (which are foreign-body implantations and which also may be too expensive in a low -resource practice). In this report from a developing country, we present the surgical description of the use of the cyst capsule as a cost-free autologous graft in the surgical repair of the dural defects of two cases of traumatic leptomeningeal cyst.
