Background :The prime imaging modality available for imaging the posterior fossa are CT and MRI. CT is non-invasive, provides 3-D cross sectional anatomy of brain, which can be reformatted in multiple planes. CT provides more detail about the nature of calcification.The posterior fossa lesions can be broadly classified into 1) Mass lesions 2) Inflammatory lesions 3) Traumatic lesions 4) Vascular lesions 5) Congenital malformations. Objective is to evaluate the computed tomography features of various types of lesions in the posterior fossa, their appearances and to determine the age and sex distribution. Materials and Methods:This was a prospective study carried out on 60 patients, age range was 0-80 years, who were referred to the Department of Radio-Diagnosis for CT at Rohilkhand Medical College and Hospital for a period of one year from November 2018 to October 2019 using 16 slice GE Brightspeed Elite third generation CT machine. Results & Conclusion:CT was highly accurate and efficient in diagnosing various posterior fossa lesions. It has an upper hand over MRI in characterization of bony changes and calcification.

Background: Imaging modalities like CT and MRI may play a vital role in diagnostic evaluation of CNS neoplasms.But the relative superiority of these modalities is intensely debated in the literature. Computed tomography, with it's wider availability, lesser cost and higher efficacy in differentiating calcification/ hemorrhage which can play a vital role in resourcepoor settings. Methods: The current study was a prospective observational study of 50 patients with supratentorial brain tumours reporting to radiology department for CT brain, in a tertiary care teaching hospital in south India. Results: Glioma (48%) was the most common tumour.Pilocyticastrocytomas and low-grade Glioma were seen in younger and middle-age population (<45 years), whereas Anaplastic astrocytoma, GBM and Oligodendroglioma showed incidence after 45 years of age.CT accurately characterized 42 of the total 50 cases. Diagnostic accuracy of CT in characterizing Meningioma, Pilocytic astrocytoma, Craniopharyngioma, Oligodendroglioma and pituitary adenomas was better than anaplastic astrocytoma and glioblastoma multiforme. Glioma mostly presented as hypo-dense lesion in NCCT while majority of Meningioma were hyper dense.Necrosis was seen in metastasis and GBM. Calcifications were seen in meningioma, craniopharyngioma and oligodendroglioma Conclusion: Supratentorial tumours can be seen in pediatric age group as well as in adults and elderly population. Glioma was the most common supratentorial brain tumour followed by meningioma and metastases. CT features are fairly characteristic in meningioma, craniopharyngioma and pituitary adenoma with overlap of imaging features in anaplastic astrocytoma, GBM and solitary metastasis.

I. I nt roduct io nBrain tumors are the most common solid tumor of childhood and the second most common malignancy after the leukemias. Primary central nervous system tumors (CNS) are the most common solid neoplasms in children. The incidence of CNS tumors is 2-5 new cases per 100000 per year, which is stable throughout the World. About 7% of the reported brain and CNS tumors occur in children aged 0-19 years .1, 2Although infratentorial tumors predominate in children, supratentorial tumors are more common in the first 2 to 3 years of life 2 . The clinical manifestations in childhood with brain tumors are largely those of increased intracranial pressure. Headache is a common early symptom. Most other symptoms are non-specific and include vomiting, cranial neuropathies and stupor and coma in late stages. 3 The largest percentage of childhood tumors (17%) are located within the frontal, temporal, parietal and occipital lobes of the brain. For children aged 0-14 years, pilocytic astrocytomas, embryonal tumors, and malignant glioma are the common tumors. The most common histologies in adolescent ages 15 -19 years include tumors of the pituitary and pilocytic astrocytoma. 1 Supratentorial intraaxial tumors are not very common in children but they are histologically more varied than in adults. Although there have been several neuroradiological investigations, accurate diagnosis by imaging modalities alone remains difficult in all cases, and final diagnosis in most cases requires histological examination. However, neuroradiological information is valuable in predicting tissue character and histological type or grade, and in helping establish treatment strategies. 4,5 The imaging modalities used are mainly CT and MR imaging with newer modalities like MR and CT perfusion, PET and SPECT.CT has become the primary imaging investigation in cases of suspected brain tumors, surpassing many other invasive imaging modalities. It has considerably high sensitivity, it is non-invasive having no hazards except ionizing radiations. CT can predict the pathological nature of a lesion with reasonable degree of accuracy. CT scan is more accurate indicator of brain tumor, yet it is not always 100% accurate. 6 MRI has its advantage of being a radiation free and multi-planar imaging facility. Hence a lesion can be seen in three planes and accurate localization of the lesion can be done. This modality provides better soft tissue characterization and can clearly demonstrate peritumoral edema, but has disadvantages like high cost , requires a long time for acquisition of the data and hence cannot be used for restless patient particularly neonates, infants or even uncooperative children. It cannot be done in patients having metallic implants for which CT is the modality of choice. 3 Newer multi-slice helical CT scanners are capable of providing highly collimated sub millimeter thickness sectional images in extremely short acquisition times and thus areas of hyperostosis or bone destruction, intratumoral calcification and early intratumoral or ...
