Aspergillus is a common saprophytic fungus that causes invasive or non-invasive disease in humans. It commonly colonizes pre-existing lung cavities. It has been earlier reported to coexist in previously operated or ruptured hydatid cysts. However there have been only few case reports of its occurrence in previously unoperated cysts in immunocompetent hosts. The present case adds to this category.
Schwannomas commonly arise from peripheral nerves. Intracranial schwannomas are comparatively rare and are seen commonly as vestibular tumors. Oculomotor nerve schwannomas are extremely rare tumors, these are usually symptomatic. A 29 year aged male presented with diplopia and blurring of vision in left eye and found to have an extra-axial lesion at left cavernous sinus involving oculomotor nerve. The excised tumor showed classic morphology of a schwannoma. Postoperatively patient developed complete oculomotor nerve palsy. The tumor recurred after 2 years. It was re-excised followed by radiotherapy.
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.
