Background: Hydrocephalous can occur at any age. Objectives: The purpose of the present study was to see the Demographic Characteristics and Etiology of Hydrocephalus Patients. Methodology: This cross sectional study was conducted in the Department of Neurosurgery at Bangabandhu Sheikh Mujib Medical University, Dhaka from April 2009 to September 2010 for a period of one and half year. Patients presented with obstructive hydrocephalus at any age with both sexes were included as study population. Detailed socio-demographic history as well as the associated etiological factors was recorded in pre designed data collection sheet. Result: A total number of 60 obstructive hydrocephalous patients were recruited for this study after fulfilling the inclusion and exclusion criteria. The mean age with SD was 17.95±19.15. Acquedctal stenosis was the most common etiology of hydrocephalous which was 31(51.7%) cases followed by posterior fossa midline tumour, CPA tumour and pineal region tumour which were 14 (23.3%) cases, 9(15.0%) cases and 6(10.0%) cases respectively. Conclusion: Obstructive hydrocephalous is most commonly found in younger age group which is caused by acquedctal stenosis.

Background: Accurate detection of astrocytomas is very difficult. Objective: The purpose of the present study was to evaluate the usefulness of Magnetic Resonance Imaging (MRI) in detection of intracranial astrocytoma. Methodology: This cross sectional study was carried out in the Department of Radiology and Imaging with the collaboration of Department of Neurosurgery and Department of Pathology at Sir Salimullah Medical College (SSMC & MH), Dhaka from January 2013 to December 2013 for a period of one (1) year. Prior to the commencement of this study, the research protocol was approved by the ethical committee (Local Ethical committee) of SSMC. All the patients presented with clinically diagnosed cases of intracranial astrocytoma who were attended in the OPD and IPD were included as study population. The sampling technique was purposive, non-random sampling method. MRI was performed in all cases. The postoperative resected tissues were examined histopathological in the respective department. Then the collected reports were compared with findings of MRI. Results: The sample size of the present study was 48 astrocytoma patients. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MRI for the diagnosis of astrocytoma are 92.0%, 80.0%, 96.0%, 67.0% and 90.3% respectively. Conclusion: In conclusion MRI has a high diagnostic validity for the detection of astrocytoma. Journal of National Institute of Neurosciences Bangladesh, July 2022;8(2):202-205
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
