abstract objective tumors of the central nervous system constitute the largest group of solid neoplasms in children and are second only to leukemia in their overall frequency during childhood. the main purpose of the present study is to determine the incidence, age, sex, location and histological diagnosis of cns tumors in children, less than 15 years of age, in the mofid children's hospital, i...

Background: Tumors of the central nervous system (CNS) are a heterogeneous group of neoplasms with different prevalence in different sex and age groups and various parts of CNS. Objectives: Determining the relative frequency of different types of CNS tumors in different ages, sex and CNS anatomical locations. Materials and Methods: This retrospective study was performed using pathological repor...

two cases of multiple concomitant cns tumors of different histologic types are presented.  one was a case of neurofibromatosis type 2 (nf2) with 6 cns tumors, and the other a case of 4 cns tumors without any evidence of nf. to our knowledge, there is no report of concomitant occurrence of 6 cns tumors in the medical literature. neuroradiological  and operative findings are illustrated and discu...

Background: About half of all brain tumors are primary, and the remainder are metastatic. Tumors of the nervous system have unique characteristics that set them apart from neoplastic processes elsewhere in the body. The World Health Organization (WHO) has classified central nervous system (CNS) tumors as grades I to IV in increasing order of malignancy. The goal of this study was to follow the...

Background & Objectives: The accurate assessment of the diseased tissue is fundamental to the diagnosis and management of disorders of the central nervous system (CNS). The ‛squash’ or ‛crush’ technique has been universally employed in the intraoperative diagnosis of CNS tumors. The aim of our study was to evaluate the accuracy of squash preparation in diagnosing CNS tumors by comparing with hi...

In 2021, the WHO revised its classification of central nervous system (CNS) tumors, which has resulted in changes to both diagnostic and treatment landscapes. At NCCN 2023 Annual Conference, this tumor board–style presentation featured 4 case studies demonstrate an evidence-based approach patients with various WHO-defined types diffuse glioma. The Guidelines have been updated reflect reclassifi...
