Study Determining Correlation between Histopathological Diagnosis and MRI Findings of Posterior Fossa Tumors
Journal Title: ​International Journal of Contemporary Medicine surgery and Radiology - Year 2018, Vol 3, Issue 2
Abstract
Introduction: The tumours that arise in the posterior fossa region are of special concern because the posterior fossa is a small enclosed space near critical brain structures, including the brain stem, the cerebellum and cranial nerves. Clinical evaluation, radiology and pathology play big role in deciding the long term prognosis. Hence, the present study was undertaken to evaluate the role of MRI in the evaluation of posterior fossa tumours and its correlation with histopathological findings. Material and Methods: The present prospective study was conducted among 30 patients who underwent MRI, diagnosed to have posterior fossa tumours and underwent surgery over a period of 1 year were included in the present study. All patients were followed up to histopathological diagnosis. Findings on histopathological examination were noted and were compared with the MRI features. All the data will be expressed in percentages. Results: Results of MRI evaluation of brain tumours revealed an accuracy of 100% for schwannomas, Meningiomas, Haemangiopericytoma, Epidermoid, Medulloblastomas and Haemangioblastoma and 50% for cerebellar astrocytoma, Ependymoma and Metastasis. Based on intra / extra axial location and MR signal characteristics of various types of tumours, we diagnosed posterior fossa tumours with 86.67% sensitivity. Conclusion: The study concluded that MRI is an accurate tool in diagnosing various posterior fossa tumours. MRI is helpful for localization of tumours and also in detecting mass effect over brain stem, herniation and hydrocephalus, thus helpful for patient management / surgical planning and aid in the early diagnosis and reduction of morbidity and mortality.
