Introduction: Arachnoid cysts are benign extracerebral collections of cerebrospinal fluid; a very low incidence has been described as part of all intracranial lesions (about 1%). They appear in the different anatomical areas of the neuroaxis where arachnoids exist; the majority are supratentorial and in the middle fossa (50-60%). In general, less than 50% of cases present manifestations that merit surgical treatment. Case report: A 55-year-old female underwent surgery due to torpid evolution as a result of an arachnoid cyst in the posterior fossa. She started suffering from episodes of pulsatile headache 2 years ago without irradiation accompanied by occasional vertigo that was attenuated with conventional analgesia. In the past week, the pain was exacerbated, as was the vertigo, intolerance to the oral route, and generalized weakness. A scheduled surgical intervention was decided on, and a histopathological study reported characteristics compatible with an arachnoid cyst. Discussion: Arachnoid cysts are an uncommon pathology that sometimes requires surgical intervention. In the case presented, the incipient clinic manifestations showed that the patient had an abrupt progression in her intensity, perhaps due to an increase in size, conditioning the increasing headache, and added symptoms. This culminated in her assessment and surgical intervention due to the important compression of the brain stem. It was considered a successful procedure due to the disappearance of the symptoms and the return to her activities. Conclusions: Surgical intervention for posterior fossa arachnoid cyst is an excellent treatment when the symptoms do not improve after having maintained an expectant conduct through conservative management.
Background: In the cavum segment, the internal carotid artery has more susceptibility formation of aneurysms. The Solitaire™ AB stent is a scaffold that do flow blood diversion and promotes the aneurysms exclusion by thrombosis. Case report: A 63-yearold female present pulsatile headache, diplopia, III left cranial nerve paresis, and carried a cavum carotid saccular aneurysms of the left carotid artery. By endovascular procedure, we placed a Solitaire™ AB stent. She recovered the III left cranial nerve function in to 2 months and we observed exclusion of the aneurysms by DynaCT in 3 months. Conclusion: The reconstruction of an artery by endovascular therapy is an alternative treatment for no ruptured paraclinoid aneurysms.
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.
