| Abstract | We report on a patient with brainstem disconnection associated with periventricular nodular heterotopia and bilateral proatlantal intersegmental arteries. The patient was a girl born after 37 weeks of gestation with birth weight of 1,938 g. Polyhydroamnios and lack of swallowing movement were noted on fetal ultrasonography. No spontaneous body movement or respiration was observed after birth, whereas facial movement was preserved. She had marked generalized weakness and absent deep tendon reflexes. She remains alive and hospitalized at 4 years of age but requires mechanical ventilation and feeding through a gastrostomy tube. MRI showed absence of the lower pons and the medulla oblongata associated with hypoplasia of the cerebellar vermis and hemispheres. In addition, ventriculomegaly and periventricular nodular heterotopia were observed in the cerebrum. MR angiography demonstrated the absence of vertebral arteries and presence of bilateral proatlantal intersegmental arteries arising from the external carotid arteries. Array-comparative genomic hybridization analysis did not show any genomic copy number aberrations. No mutation was found in the FLNA gene or the EN2 gene. The constellation of the malformations of our patient suggested that genes related to the development of the central nervous and vascular system may be involved in the pathogenesis of brainstem disconnection. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
