Emergence of Groupwise Registration in MR Brain Study

Background- The danger of intracranial pathology is that expansion in an enclosed space leads to brain compression causing ischemia, swelling and loss of function that can be permanent and possibly fatal. Methods- This was a simple observational prospective study carried out at the Department Of Radio-Diagnosis And Modern Imaging, S.P.M.C. & A.G. Of P.B.M. Hospitals, Bikaner. All the patients presented for MR brain study with some neurological complaints and showed positive findings on MRI were included in this study. Results- out of total 120 stroke cases, there were 33 cases of acute arterial infarct, 4 of HIE, 6 cases of ICH, 76 of subacute arterial infarct and 1 case of venous infarct. Similarly, out of total 17 cases of tumors, 9 cases were of meningioma, 4 of lymphoma, 2 of glioma and metastasis each. Out of total 9 cases of infections, there were 3 cases of abscess, 2 of encephalitis and 4 of tubercular meningitis. There were 1 case of pontine myelinolysis, 2 cases of ADEM and 1 cases of diffuse axonal injury in this study. Conclusion- Stroke comprised the majority of lesions at 120 cases (80% of the total cases studied). Keywords: MRI, Brain, lesion.

Brain Study

There are few literature reports of MR study in children with Leber's congenital amaurosis, a severe early onset autosomal recessive retinal dystrophy. We describe the clinical and neuroradiological findings in 35 patients. Of these, 22 had a normal brain MR scan, four showed mild dilatation of the cortical sulci, two had mild optic-chiasmatic thinning, three showed aspecific white matter changes not involving the primary visual pathway and four had “molar tooth” mesencephalic malformation. Our series confirms literature findings of normal signal and morphology of the primary optic pathway. Posterior cranial fossa abnormalities, defined as rhombencephaloschisis, was associated with a clinical picture different from that of the other patients. This abnormality is encountered in different malformations associating cerebellar, ocular and renal abnormalities. MR brain study in children with Leber's congenital amaurosis is recommended not only to assess the visual pathways, but also to analyse the posterior cranial fossa and cerebellum.
