[Intramedullary spinal cord metastasis from gastric adenocarcinoma: Case report and review of literature].

Intramedullary spinal cord metastases are very rare and usually associated with lung or breast cancer, with gastric origin being exceptional. Their clinical onset tends to be faster than that of primary intramedullary tumours. The most common early symptoms of intramedullary spinal cord metastasis are motor deficit in one or more limbs, pain, sensory loss, and sphincter disturbances.

Foix-Chavany-Marie syndrome caused by a disconnection between the right pars opercularis of the inferior frontal gyrus and the supplementary motor area.

Foix-Chavany-Marie syndrome (FCMS) is a rare type of suprabulbar palsy characterized by an automatic-voluntary dissociation of the orofacial musculature. Here, the authors report an original case of FCMS that occurred intraoperatively while resecting the pars opercularis of the inferior frontal gyrus. This 25-year-old right-handed man with an incidentally diagnosed right frontotemporoinsular tumor underwent surgery using an asleep-awake-asleep technique with direct cortical and subcortical electrical stimulation and a transopercular approach to the insula.

[Minimally invasive approach of extramedullary intradural spinal tumours. Review of 30 cases].

Objective: To analyse the safety and effectiveness of a microsurgical unilateral approach in minimally invasive surgery of extramedullary, intradural spinal tumours.

Materials And Methods: This was a retrospective study of 29 patients with 30 extramedullary, intradural spinal tumours approached through unilateral laminectomy -hemilaminectomy. Epidemiological data, location and histology of the lesions and radiological and clinical evolution of the patients were recorded.
