CAMPERO, Alvaro y RIVADENEIRA, Conrado. Abordaje extremo lateral transcondilar para resecar un meningioma anterior del foramen magno. Rev. argent. neurocir. [online]. 2006, vol.20, n.4, pp. 161-164. ISSN 1850-1532.
Objective: To describe the far-lateral transcondylar approach performed to remove a meningioma of the anterior portion of the foramen magnum. Description: A woman, 24-years old, with tetraparesis, greater in the right side, and paresis of the IX, X, and XI right cranial nerves, with a 9 months history. The MRI showed a tumor in the anterior aspect of the foramen magnum (isointense in T1 and T2, with homogeneous enhance after gadolinium administration). Intervention. In December 2005 the surgery was performed (far-lateral transcondylar approach), with complete removal of the lesion. Histology: cordoid meningioma. The patient had a good outcome, with complete recovery of her neurological deficits. In the last control she was asymptomatic. Conclusion. In this case, the far-lateral transcondylar was the most appropriate approach to completely resect a meningioma of the anterior portion of the foramen magnum.
