J Neurol Neurosurg Psychiatry 2005;76:1686–1692. doi: 10.1136/jnnp.2004.051607 Background and objectives: Brain tumours responsible for longstanding partial epilepsy are characterised by a high prevalence of dysembryoplastic neuroepithelial tumour (DNT), whose natural evolution is much more benign than that of gliomas. The preoperative diagnosis of DNT, which is not yet feasible on the basis of available clinical and imaging data, would help optimise the therapeutic strategy for this type of tumour. This study tested whether [11C]-methionine positron emission tomography (MET-PET) could help to distinguish DNTs from other epileptogenic brain tumours.

  • Is High Altitude an Emergent Occupational Hazard for Primary Malignant Brain Tumors in Young Adults? a Hypothesis
    Published online: 2021-06-03 Original Article Is High Altitude an Emergent Occupational Hazard for Primary Malignant Brain Tumors in Young Adults? A Hypothesis Abstract Neelam Sharma, Introduction: Brain cancer accounts for approximately 1.4% of all cancers and 2.3% of all Abhishek cancer‑related deaths. Although relatively rare, the associated morbidity and mortality affecting Purkayastha1, young‑ and middle‑aged individuals has a major bearing on the death‑adjusted life years compared to other malignancies. Over the years, we have observed an increase in the incidence of primary Tejas Pandya malignant brain tumors (PMBTs) in young adults. This observational analysis is to study the Department of Radiation prevalence and pattern of brain tumors in young population and find out any occupational correlation. Oncology, Army Hospital (Research and The data were obtained from our tertiary care cancer institute’s malignant Materials and Methods: Referral), New Delhi, diseases treatment center registry from January 2008 to January 2018. A total of 416 cases of PMBT 1Department of Radiation were included in this study. Results: Our analysis suggested an overall male predominance with Oncology, Command most PMBTs occurring at ages of 20–49 years. The glial tumors constituted 94.3% while other Hospital (Southern Command), histology identified were gliosarcoma (1) gliomatosis cerebri (1), hemangiopericytoma (3), and pineal Pune, Maharashtra, India tumors (3). In our institute, PMBT constituted 1% of all cancers while 2/416 patients had secondary glioblastoma multiforme with 40% showing positivity for O‑6‑methylguanine‑DNA‑methyltransferase promoter methylation. Conclusions: Most patients belonged to a very young age group without any significant family history.

Ferguson and Margarethe Hoenig Received: 19 April 2016; Accepted: 22 June 2016; Published: 27 June 2016 Abstract: An eight-year-old, neutered, female, long-haired cat was presented with a three-week history of progressive lethargy, unlocalized pain in the cervical and lumbar spine, and unwillingness to move. An MRI (magnetic resonance imaging) of the brain revealed poorly circumscribed regions of non-contrast-enhancing heterogeneous T2 hyperintensity within the ventral forebrain and midbrain. A mass effect and evidence of increased intracranial pressure, including transtentorial herniation of the midbrain and herniation of the cerebellar vermis through the foramen magnum, were also observed. Due to progressive clinical decline and MRI results, the cat was humanely euthanized. Gross examination of the brain confirmed caudal transtentorial and foramen magnum herniation. The ventral aspect of the forebrain, midbrain, and brainstem were soft and had loss of detail, but lacked a grossly discernible mass. Histopathological examination found a poorly delineated neoplastic mass composed of hyperchromatic cells with indistinct cytoplasm, ovoid to elongate or curved nuclei, and indistinct nucleoli. The cells lacked immunoreactivity for Olig2, GFAP, Iba1, CD3, and Pax5.
