Papillary glioneuronal tumor (PGNT) is a rare brain tumor grouped under mixed glioneuronal tumors according to the World Health Organization Classification of the Central Nervous System. The natural history of this pathology is not yet well documented. We report a case of PGNT that increased in size after a follow-up period of 10 years. An enlarged cyst wall and nodule showed a low intensity signal on T2*-weighted, suggesting hemorrhage during the clinical course. Characteristic pathological findings along with absence of  mutation identified the tumor as PGNT. The tumor characteristics of PGNT are discussed based on the presented case, with reference to the existing literature.

Enlargement of papillary glioneuronal tumor in an adult after a follow-up period of 10 years: a case report.

Mystery Case: Parietal lobe epilepsy with ictal manifestation of Gerstmann syndrome.

Molecular and genetic alterations of non-small-cell lung cancer (NSCLC) now play a vital role in patient care of this neoplasm. The authors focused on the impact of epidermal growth factor receptor mutation (EGFR-mt) status on the survival of patients after brain metastases (BMs) from NSCLC. The purpose of the study was to understand the most desirable management of BMs from NSCLC.

The impact of EGFR mutation status and single brain metastasis on the survival of non-small-cell lung cancer patients with brain metastases.

Stereo-electroencephalography (SEEG) has gained global popularity in recent years. In Japan, a country in which invasive studies using subdural electrodes (SDEs) have been the mainstream, SEEG has been approved for insurance coverage in 2020 and is expected to gain in popularity. Some concepts supporting SEEG methodology are fundamentally different from that of SDE studies. Clinicians interested in utilizing SEEG in their practice should be aware of those aspects in which they differ. Success in utilizing the SEEG methodology relies heavily on the construction of an a priori hypothesis regarding the putative seizure onset zone (SOZ) and propagation. This article covers the technical and theoretical aspects of SEEG, including the surgical techniques and precautions, hypothesis construction, and the interpretation of the recording, all with the aim of providing an introductory guide to SEEG.
