Purpose: To evaluate with 1H-magnetic resonance spectroscopy (MRS) the metabolites rations of the foramen of Monro's region in patients with tuberous sclerosis complex (TSC).
Method: Twelve patients with TSC and an age and gender-matched control group underwent MR imaging at a 1.5T scanner, and 1H-MRS at the foramen of Monro level with a multivoxel acquisition. Similar volumes of interest were selected in each side of the foramen of Monro and in the basal ganglia (lentiform nuclei). The obtained N-acetylaspartate (NAA), creatine (Cr) and choline (Cho) peak amplitude values and ratios were studied. The statistical analysis was performed and p<0.05 was considered statically significant.
Results: There was no significant difference between the NAA/Cr and Cho/Cr ratios near to the foramen of Monro and basal ganglia of the TSC patients compared with the controls (p>0.05).
Conclusion: The NAA/Cr and Cho/Cr ratios near to the foramen of Monro and basal ganglia of TSC patients are similar to the rations obtained in the control group.

Ganglioneuroblastoma (GNB) is a rare tumour of neuroectodermal origin consisting of a varying proportion of neuroblasts and ganglion cells. GNB arises from sympathoadrenal tissue usually affecting young children. Very few cases of brain GNB have been reported in the literature.

Background: Colloid cysts (CCs) are benign lesions commonly located in the third ventricle, near the foramen of Monro. They constitute about 0.5%-1% of all intracranial tumors.

Background: Ventriculoperitoneal (VP) shunt surgery is the primary treatment for patients with idiopathic normal pressure hydrocephalus (iNPH). This study compared the outcomes of VP shunt placement using electromagnetic (EM) navigation versus standard methods in patients with iNPH, focusing on catheter accuracy and postoperative complication rates.
Methods: This retrospective study included 31 patients with iNPH who underwent standard shunt placement using anatomical landmarks and 50 patients who underwent EM-guided shunt placement.

Subependymal giant cell astrocytoma (SEGA) is a rare, low-grade glioma typically associated with tuberous sclerosis (TS) and mutations in the TSC1 or TSC2 genes. It is characterized by an intraventricular location, an expansive growth pattern, and the expression of glial and neural markers. TTF-1 expression is considered a sensitive marker of SEGA, likely reflecting its origin from progenitor cells in the caudothalamic groove.

Objective: Intraventricular baclofen has been reported as an alternative to intrathecal baclofen for managing refractory spasticity and dystonia in some circumstances. In this report, we described a frame-based stereotactic approach for precisely positioning of the infusion catheter into the third ventricle.
Material And Methods: High resolution contrast-enhanced anatomical MR sequences was acquired prior to surgery for pre-planning.
