Chordoid Meningioma: The Rarest Subtype of Grade II Meningioma.

Chordoid meningioma, a rare WHO grade II tumor, is known for its aggressive behavior and high recurrence rate. We report a case of a 44-year-old woman with progressive left-sided weakness, where imaging revealed a 3.0 cm lesion in the right sphenoidal wing with significant midline shift and edema.

Maternal genomic profile, gestational diabetes control, and Mediterranean diet to prevent low birth weight.

Low birth weight (LBW) is associated to poor health outcomes. Its causes include maternal lifestyle, obstetric factors, and fetal (epi)genetic abnormalities. This study aims to increase the knowledge regarding the genetic background of LBW by analyzing its association with a set of 110 maternal variants related to gestational diabetes mellitus, in the setting of a nutritional intervention with Mediterranean diet.

Increase of primary intracranial sarcoma in children: Clinical manifestations, diagnosis, and management.

Background: Primary intracranial sarcomas (PISs) are very rare malignant tumors, and there is paucity of data on it, exclusively in patients <18 years old. We report pediatric PIS at a tertiary hospital in Peru, where the incidence of PIS has increased in recent years.

Methods: We retrospectively analyzed data in children diagnosed with PIS based on clinical presentation, imaging studies, and histopathology between January 2020 and December 2023.

Radiosurgery for Hypothalamic Gliomas: A Case Report and Clinical Guidelines Form a Neurosurgical Center of Excellence.

Hypothalamic gliomas, though rare, present significant challenges in neuro-oncology due to their critical location and high morbidity risk. Pilocytic astrocytoma is the most common subtype, requiring a delicate balance between tumor control and preservation of neurological function. This study explores radiosurgery as a viable treatment option for hypothalamic gliomas, with a focus on low-grade lesions.
