 Hello everyone, Myself Kunam. Today, I'm going to present my topic, Evaluation of Ring Enhancing Legions in a Patient Complaining of Caesar on MRF. Introduction, Enhancing Brain Legions with Clinical Pocal Caesars and Incongruous Diagnostic Feature on Anatomical Neuroimaging is an area that continues to challenge attending neurologists. The common differential in general population include tuberculomas, neurocystic sarcosis, brain abscesses and metastatic legions. In AIDS patients, the major differential diagnosis is between lymphoma and CNS toxoplasmosis. The purpose of the study is to examine intracranial ring enhancing mass lesion in patient complaining of Caesar using MRF, Plain Plus Contrast Study. A main objective, the evaluate ring enhancing lesion in patient complaining of Caesar, study type cross sectional observational study, material and methodology. In 110 patients complaining of Caesar doing MRF in Government Medical College or Ranga Bath in age of 10 to 60 years, this was a hospital based perspective study evaluating all cases of Caesar, any episode, any type and with any time duration. From a period of January 23 to January 24, children above age of 10 years, those having definitive CNS infection with head injury, cerebra palsy and those not showing in ring enhancing brain lesions were excluded from the study. Role of MRI in confirmation of differential diagnosis where studies results were correlated with clinical follow up protocol, routine sequences like axial and core T1, axial and core flare images, axial T2 and SWI imaging, DWI imaging, double inversion recovery in sequences and T1 weighted sequences with contrast study. Further you can add a spectroscopy for more confirmation. Our first case is tuberculoma, 50 year patient complaining of Caesar showing conglomerated ring enhancing lesion in right anterior temporal region which is showing hyperintense on T2, no restriction on flare or mild diffusion restriction on TWI which can be seen in tuberculomas, no blooming on SWI, hyperintense on T1, mostly likely suggestive fundamental region like tuberculoma. The next patient is 45 year old with Caesar showing incomplete ring enhancing pattern in right parietal region showing a eccentric located scalus in flare images, no restriction on DWI, mild blooming on SWI and hyperintense on T1 weighted images. This it is showing multiple different stages also. This is mostly a granular matters region, likely neurocystisarcosis. The Escobar staging for neurocystisarcosis are four that is vesicular with the viable parasite and intact membrane, colloidal vesicular after four to five years untreated or with early treatment the cyst fluid becomes turbid as the membrane become leaky, edema surrounds the cyst, this is the most symptomatic stage, granular nodular stage, edema decreases as the cyst retracts further enhancement persist. Then the final stage is nodular calcified stage which is a end stage quiescent calcified cyst acid in this stage. The next patient is 20 year old, complaining of Caesar showing complete ring enhancing region in right parietal region showing surrounding edematous changes and distriction restriction, likely suggestive of abscess. The next case is immunocompromised patient complaining of Caesar shows multiple ring enhancing lesions in bilateral cerebellar hemispheres with surrounding perillational edematous changes on flare images and mild restriction on DWI shows blooming on SWI likely to toxoplasmosis. The next case is glioblastoma multiformis. This is a patient complaining of Caesar, 70 year old, showing ring in complete irregular ring enhancing region in bilateral parietal region with surrounding perillational edema showing restriction, mild restriction on DWI. This is mostly a case of pneumoplastic lesion high grade glioblastoma. Pneumonic for ring enhancing lesion is magical doctor M metastasis A abscess. G glioblastoma multiformis I impact in subacute phase C contusion A vascular malformation, L lymphoma, DT malating, this is our radiation. In summary, how to evaluate ring enhancing lesion is D2 weighted signal hyper or hyper intense flare restriction present or not, ring smooth or irregular, DWI restricted or facilitated SWI, SWI peripere blooming or not, FESTA, eccentric scolitis, contrast complete or incomplete enhancement, perfusion and MR spectroscopy. Conclusion, common cause of symptomatic epilepsy in 10 to 60 years age group with ring enhancing region on neuroimaging at liver polymer followed by neurocystic surfaces and brain abscesses which can be diagnosed by careful history through thorough clinical examination and appropriate investigation to plan for timely management for favorable results. In addition to the number of patients who are under the age group of 20 to 40, the most common type is TB, mostly location in parietal region. Discussion, although secondary focal diseases with ring enhancing lesion is a novel phenomena in developing countries like India, the volume of literature is spare. In spite of attending magnitude of public health demands, scientific studies are a key analysis region accounts for 95% of the ideology procedure in children. Two of the 42 cases in our study, 16 cases were found female and 26 were male, with male to male is to female ratio 1.6 to 1. Most people belong to the age group of 20 to 40, English and eldest at the presentation where 5.3 years, 13.8 years respectively with a main age of 32 years. Small children mostly remain indoor where safe from the risk factor and infection. Similarly, males being more exposed to outside environment and contact with disease people were prone for different diseases. Those are also neglected in Indian serenity for less attention. Thank you.
