A non-enhancing cyst-like structure within the pars intermedia of PA usually located in the midline is a prominent MRI feature of coexisted PA and RCC. Total resection of coexisted RCC must be achieved and fat graft should be avoided during surgery because of high recurrence rate of RCC and complicated hypophysitis.
Background: Tumor-like demyelinating lesion is a rare form of IP, often indistinguishable from brain tumors on CT or MR imaging. Case presentation: We report here a case of pathologically confirmed tumor-like demyelinating lesions. The clinical manifestations, image feature and pathology of this case are also discussed together with a review of the relevant literature. Conclusion: The correct diagnosis of tumor-like demyelinating lesion mainly depends on the postsurgical histopathologic examinations. We suggest complete resection of the intracranial lesion and involved dura, followed by administration of short term oral prednisolone therapy will be good for preventing recurrence.
In this paper, we introduce a new embossing holographic technique: holographic dual-beams interference technique. Using this technique, we can make more dynamic and brighter 2D holograms, witch are used widely recently. Some methods of preparing images by computer are discussed in the paper.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
