BACKGROUND Choroid plexus tumors (CPTs) are rare brain tumors that originate from the choroid plexus epithelium and range from low-grade papillomas to overtly malignant carcinomas, and can occur in newborns. According to the World Health Organization's histological classification, atypical choroid plexus papilloma (aCPP) is an intermediate-grade (Grade II) lesion characterized by an increased mitotic rate. It is difficult to distinguish CPTs on imaging during the early stages.

Article Synopsis
  • The study aimed to investigate how social determinants of health (SDoH), specifically socioeconomic status using the Yost Index, affect disparities in care and outcomes for pediatric CNS tumors in the US.
  • Researchers conducted a retrospective analysis of data from over 18,000 patients aged 19 or younger with CNS tumors from 2010-2018, analyzing various demographic and treatment-related factors.
  • Results indicated significant disparities in mortality risks, treatment accessibility, delays, and cancer staging related to certain SDoH factors, suggesting that both individual and community-level influences play a critical role in health outcomes for these patients.

Background: Considering the invasiveness of the biopsy method, we attempted to evaluate the ability of the gamma distribution model using magnetic resonance imaging images to stage and grade benign and malignant brain tumors.

Methods: A total of 42 patients with malignant brain tumors (including glioma, lymphoma, and choroid plexus papilloma) and 24 patients with benign brain tumors (meningioma) underwent diffusion-weighted imaging using five b-values ranging from 0 to 2000 s/mm2 with a 1.5 T scanner.

Article Synopsis
  • - A 57-year-old man was diagnosed with a tumor located in the cauda equina, which had metastasized to both the spinal cord and intracranial areas, causing severe lower back pain and balance issues.
  • - Imaging revealed a large mass affecting the lumbosacral region, along with intradural and intracranial metastases, prompting further investigation of its pathology.
  • - Although the tumor's features initially suggested a choroid plexus tumor, additional tests, including methylation profiling, confirmed the diagnosis as a choroid plexus papilloma, highlighting its unusual location and metastatic behavior.

Aim: To highlight the critical role of molecular profiling of choroid plexus epithelium tumors (CPTs) in guiding individualized treatment strategies.

Material And Methods: Histopathological diagnoses were obtained from surgically resected tumors at Centro Medico Nacional 20 de Noviembre, Mexico City (Department of Neurosurgery). The cohort comprised four children (two females and two males) and three adults (one male and two females).

Choroid plexus papilloma (CPP) is a rare, slow-growing, and typically benign brain tumor that predominantly affects children. CPP is characterized by well-defined circular or lobulated masses in the ventricles, leading to symptoms related to increased intracranial pressure and hydrocephalus. CPP diagnosis relies on a combination of clinical presentation, imaging findings, and histological examination.

Choroid Plexus Papilloma Tumor of the Ovary: A Case Report.

Sisli Etfal Hastan Tip Bul

June 2024

Department of Gynecological Oncology, University of Health Sciences Türkiye, Basaksehir Cam and Sakura City Hospital, Istanbul, Türkiye.

This is a case report of a 19-year-old nulligravid patient with a choroid plexus papilloma tumor in a mature cystic teratoma in the right adnexal area. The patient, who had abdominal pain and dyspepsia, showed a 9 cm diameter mass with a solid/cystic component, initially interpreted as a dermoid cyst in the right adnexal region. Mature cystic teratoma is a benign germ cell tumor and is common in women during the reproductive period.

Choroid plexus papilloma (CPP) is a rare benign intracranial tumor origin that predominantly manifests in the lateral ventricle in children, accounting for 0.3%-0.6% of all primary intracranial tumors.

Article Synopsis
  • Choroid plexus tumors (CPTs) are rare and aggressive brain tumors with specific grading criteria, but recent cases show discrepancies between their histological diagnosis and actual behavior.
  • A study reviewed clinical data from patients diagnosed with CPTs at Boston Children's Hospital and conducted DNA methylation profiling to find correlations with WHO histologic grades and survival outcomes.
  • The results suggest that DNA methylation profiling could enhance clinical decision-making for CPTs by providing better prognostic insights than histologic grading alone, especially due to the uncertainty in treatment options for these tumors.

Choroid plexus tumors (CPTs) are intraventricular tumors derived from the choroid plexus epithelium and occur frequently in children. The aim of this study was to investigate the genomic and epigenomic characteristics of CPT and identify the differences between choroid plexus papilloma (CPP) and choroid plexus carcinoma (CPC). We conducted multiomics analyses of 20 CPT patients including CPP and CPC.

Choroid plexus tumors (CPT) are rare and highly vascularized neoplasms that have three histologically confirmed diagnoses, including choroid plexus papilloma, atypical choroid plexus papilloma, and choroid plexus carcinoma (CPC). This study aimed to determine the epidemiology and survival of patients with CPTs and develop a nomogram to quantify the prognosis of the patients with CPT. Data of 808 patients who were diagnosed as CPT between 2000 and 2020 was obtained from the surveillance, epidemiology, and end results database.

Atypical choroid plexus papilloma is a rare World Health Organization grade 2 intraventricular tumor arising from the epithelium of the plexus choroid with intermediate clinical-pathological features between the benign choroid plexus papilloma and the malignant choroid plexus carcinoma. The main criteria for differentiation are histopathologic, with difficulties in distinguishing it from choroid plexus papilloma based on imaging features. We report the case of a 4-year-old female presenting with headaches and altered mental status.

Background: Choroid plexus papillomas (CPPs) are rare neoplasms arising from choroid plexus epithelium representing <1% of all intracranial tumors. Symptoms vary based on location and regional mass effect; however, hydrocephalus is common due to cerebrospinal fluid flow obstruction and/or overproduction. Distant site metastasis or formation in extraventricular sites is rare.

Choroid plexus papillomas are rare brain neoplasms, primarily observed in children, and typically manifest with symptoms indicative of heightened intracranial pressure and cerebral irritation. In addition, the tumor's localization varies with the patient's age, and diagnostic and therapeutic approaches predominantly rely on imaging findings and surgical interventions, with histopathological examination being essential for confirmation. This study outlines a unique instance of choroid plexus papilloma in a 30-year-old female, who presented with severe headache and vomiting, subsequently revealing hydrocephalus on Brain CT.

Choroid plexus tumors (CPTs) are rare neoplasms found in the central nervous system, comprising 1% of all brain tumors. These tumors include choroid plexus papilloma (CPP), atypical choroid plexus papilloma (aCPP), and choroid plexus carcinoma (CPC). Although gross total resection for choroid plexus papillomas (CPPs) is associated with long-term survival, there is a scarcity of prospective data concerning the role and sequence of neoadjuvant therapy in treating aCPP and CPC.

Choroid plexus papillomas are relatively rare vascular tumors. In this video, the authors present a pediatric patient who underwent exoscopic removal of the fourth ventricle choroid plexus papilloma with the use of a midline suboccipital osteoplastic craniotomy. The exoscope in the fourth ventricle lesion helps to improve visualization in all directions, with the surgeon being able to maintain a comfortable position throughout the procedure.
