Objectives: To determine the frequency of cases detected with hydrocephalus in cases presenting with TBM. Material & methods; This cross sectional study was conducted during January to July 2019. The detailed demographic data was collected. The cases of TBM were selected on clinical and laboratory diagnosis and then they underwent CT scan of brain (plain) and diagnosis of TBM was made in BMRC scale. Results; In this study, 300 cases of TBM were selected and, out of these 180 (60%) were males and 120 (40%) females with mean age of 43.11±9.13 years. There were 18 (6%) cases in stage I, 195 (65%) in II and 57 (29%) in stage III of TBM. Hydrocephalus was observed in 144 (48%) of the cases. There was no significant difference in terms of gender and age groups with p values of 0.67 and 0.58. The results were significantly higher in those that had stage III of TBM where it was see in 57 (65.52%) out of 87 cases as compared to 81 (41.54%) cases in stage II and 6 (33.33%) in stage I of their respective groups with p value of 0.02 as in table 03. Conclusion; Hydrocephalus is seen nearly in half of the cases with TBM and it is significantly high in cases that had stage III of TBM. Key words; TBM, hydrocephalus.
