Their location close to vital neurovascular structures makes traditional treatment modalities (surgery and radiation) challenging and potentially fraught with morbidity. The 2021 WHO classification has divided what was previously considered two subtypes of craniopharyngioma into separate entities.

Background: Meningiomas are the most frequently diagnosed benign intracranial tumors. However, meningioma en plaque (MEP) is a rare subset accounting for 2.5% of all meningiomas and is characterized by flat, carpetlike proliferation along the dura, typically arising in the spheno-orbital region, and, therefore, causes proptosis, decreased visual acuity, and orbital pain.

Purpose: This study investigates the rare occurrence of tumor-to-tumor metastasis in Pituitary Neuroendocrine Tumors (PitNETs), also known as pituitary adenomas, aiming to enhance understanding of its diagnostic and therapeutic challenges. We report two cases from our institution of tumor-to-tumor metastasis involving PitNETs, followed by a systematic literature review.

Methods: We conducted a comprehensive literature review using PubMed and Google Scholar databases.

Objective: There is a long-standing debate in the literature whether depressive symptoms increase the risk of dementia in older with mild cognitive impairment (MCI). We aim to conduct a meta-analysis of studies that evaluated the risk of dementia in subjects with MCI and depressive symptoms compared with subjects with MCI and no depressive symptoms.

Methods: We calculated the relative risk of progression to dementia in subjects with MCI and depressive symptoms compared with subjects with MCI and no depressive symptoms using a generic inverse variance method with random effect models.
