Ring enhancing CT lesions--a diagnostic dilemma.
We studied 68 such cases of RECTL with follow up ranging from 3 months to 3 years. Patients were divided into 3 groups depending on the size of ring ie. Group I (less than 5 mm), Group II (5-10 mm), Group III (10-20 mm). Maximum cases were in Group II (42), in the age group 20-40 years. 60 cases presented with seizures. Single ring was seen in 46 cases and multiple rings in remaining 22 cases. There were 22 cases of tuberculoma, 15 neurocysticercosis, 15 disappearing lesions, 4 malignancy, 2 abscess, 1 each showing infarction and gliosis and 8 of unknown etiology. Partial or total excision biopsy was done in 18 cases of which 3 were due to tuberculoma, 7 neurocysticercosis, 4 tumours, 2 abscess and 1 each due to infarction and gliosis. We found that RECTL could be a real diagnostic problem, which could be solved only be repeated clinical examination and CT Scan with excision biopsy in some selected cases.
