| Abstract | A case report and five additional cases from the literature of angiographically demonstrated abnormal vascularization of chromophobe adenomas are presented. The appearance is that of a fine network of vessels appearing in the arterial phase and a homogeneous blush beginning in the capillary phase and lasting throughout the venous phase. The network is derived from dilated branches of the extradural internal carotid artery and is seen in the arterial phase. The stain, appearing in the venous phase, is due to filling of tiny sinusoidal channels and thin-walled vessels throughout the stroma. All the patients had large, actively growing tumours which compressed and infiltrated surrounding structures. Complete tumour removal was not possible in the patients operated upon. The combined morbidity-mortality rate was 83% and was due to the large tumour size, adherence to vital centres, extreme vascularity during surgical removal, and propensity to bleed spontaneously. The appearance of abnormal vascularity in a pituitary adenoma suggests a poor prognosis. |

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.
