HISTOPATHOLOGICAL SPECTRUM OF TEMPORAL LOBE TUMORS; A 12 YEAR OBSERVATIONAL STUDY

  Abstract :

The Central Nervous System tumor comprises ~2% of all the tumors, an overall increase has been observed especially in less developed countries. This increase in the incidence may be due to exposure of population to various risk factors or improved diagnosis with advancement in the ancillary studies. Tumors of the temporal lobe show varied clinical behavior e.g., some low grade tumors with typical pathological features carry a favourable prognosis after total tumor excision. AIMS AND OBJECTIVES; To study the histopathological spectrum of tumors of the temporal lobe. MATERIAL AND METHODS. An observational study ( analysis of temporal lobe tumors) in a tertiary care hospital using data from May 2005 through May 2017 RESULTS The total number of cases in our study was 206, which included the primary brain tumors of the temporal lobe diagnosed In our study, the maximum number of patients were in the age group of 21-40 years (40.8%) The male to female ratio was 2.03:1 in our study The most common clinical symptom was headache which was seen in 89.8% of cases followed by seizures (53.9%) GBM was the most common histopathological subtype in our study,followed by PXA and glioneuronal tumors.SUMMARY AND CONCLUSION In addition to gliomas which form the major subtype in temporal lobe,glioneuronal tumors have emerged as a significant group of tumors in the temporal lobe with a good prognosis as they mostly belong to a lower grade
