[Fluorescence-guided resection with 5-aminolevulinic acid of an intramedullary tumor].

Fluorescence-guided resection with 5-aminolevulinic acid (5-ALA) has demonstrated its usefulness in the resection of malignant cerebral gliomas. It also seems useful for the treatment of other types of cerebral and intramedullary neoplasms. We present the case of a patient with an intramedullary tumor in who fluorescence- guided resection was useful for intraoperative localization, definition of small tumor nodules and in order to achieve a complete resection of the tumor.

[Intramedullary schwannomas. Report of two cases].

Intramedullary schwannomas are benign tumors that arise from clusters of Schwann cells embedded in the medullary parenchyma. They are very rare and account for 0.3 to 1.
