Abstract :

Objectives: To evaluate patients with ring enhancing lesion (REL) and associated clinical features thereby charting out diagnosis and treatment outcome of RELs. Material and methods: A cross–sectional observational study of 25 patients (age >12 years), with REL on MRI ain, was done over 12 months. Headache and seizures, and signs of hydrocephalus, meningitis and focal deficits were clinically assessed. Relevant investigations were sent, and correlated with clinical features and MRI findings. Response to medical therapy (empirical or specific) was evaluated clinically and on repeat MRI after 6 weeks. Several causes of RELs like infectious, neoplastic and inflammatory were detected. Of these, only cases of neurocysticercosis are highlighted. Results and Conclusions: Out of 25 patients, 8 (32%) had neurocysticercosis (5 males and 3 females), mostly between 21–40 years age; seizures were present in 100% and headache in 88%. Routine CSF studies were normal in 100%. Anti Cysticercii Antibody – CSF was conducted in 4 out of 8 patients and was positive in 3 of these (75% positivity). 7 of 8 patients had a single REL; size of REL in 7 of 8 patients was between 1 to 10 mm. Lesions were scattered at various sites including frontal lobe and temporal lobe (2 each), and others. A combination of anti–convulsants, anti–helminthics (Albendazole) and steroids was instituted. On repeat scan after 3 weeks of therapy, complete resolution was observed in 6 patients (75%), and calcification and regression was observed in one patient each. We concluded that neurocysticercosis has an excellent prognosis if treated appropriately.
