Hydatid disease is a serious public health problem in developing countries. Spinal hydatid cysts account for 1% of all cases of hydatid disease and the primary intradural extramedullary hydatid cyst is exceptional. We report a case of 75-year-old women presented with a history of backache, leg pain, difficulty in walking, and bladder incontinence. Thoraco-lumbar MRI has showed an intradural process extending from L2 to S5, a low intensity signal on T1 weighted images and a high-intensity signal on T2 weighted images, which were not enhanced after gadolinium injection. There was no vertebral involvement. The patient underwent surgery, by a posterior approach we perform L2S1 laminectomy. After opening the dura multiple vesicles were found scattered among the roots, with no adhesion to meninges or nervous structures. The outcome was good. Albendazole therapy is obligatory.
Meningiomas are the most common primary brain tumors, Orbital invasion usually invades as an extension of the sphenoid wing meningiomas. We report the case of a 54-year-old man who presented with frontotemporal intraosseous meningioma with intraorbital invasion.
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.
