AbstractBackground: The two most common differential diagnosis of this lesion in clinicalpractice include neurocysticercosis (NCC) and tuberculomas. In Indian paediatric patients the most common radiological abnormalities seen in epilepsy is single small enhancing computed tomography lesions. It is difficult to differentiate between tuberculomas and a single cysticercalgranulomas.
Aims & Objectives: To determine the etiological nature of different diseases, ring enhancing lesions on CT and also compare the CT morphology with pathological diagnosis whenever it is possible.
Methodology: It is prospective observational study. This study was carried out in 100 patients seen at the department of radio diagnosis and imaging, Shadan institute of Medical Sciences and research centre. Hyderabad between (Mention study periods). All the patients under went CSF analysis and CT examination.
Results: In the present study, the age of patients in our series was 5years to 79 years. Maximum cases were seen in age group 21-50years (60 cases).20 cases were seen above 50 years and the remaining 20 cases below the age of 20 years. There were 58 males and 42 females. Male to female ratio was 4:3.In the etiological diagnosis, neurocysticercosis (NCC) were 45% (45), 22% (22) were tuberculoma as, 12% (12) were metastasis, 11(11%) were brain abscess and 10 (10%) were GBM. Single ring was seen in 56 cases (56%), while multiple rings (two or more) seen in 44%, (44 cases). 52% patients had size of ring less than 10mm, while 48% cases had ring more than 10mm in size.
Conclusion: CT is still the preferred investigation in many centres due to wide availability, lower cost, less time consumption particularly in paediatric patients.
