A 51-year-old female presented with a rare case of choroid plexus papilloma originating in the sella turcica manifesting as headaches that was not readily distinguishable preoperatively from pituitary adenoma. Head magnetic resonance imaging revealed a tumor extending from the sella turcica to the suprasellar cistern. The tumor was removed via an endonasal transsphenoidal approach. Histological examination indicated a papillary structure covered with a layer of columnar epithelial cells that resembled normal choroid plexus. These findings, together with immunohistochemistry, led to a diagnosis of choroid plexus papilloma.
Background and Purpose: The optimal use of antiplatelet therapy for intracranial branch atheromatous disease (BAD) is not known. Methods: We conducted a prospective multicenter, single-group trial of 144 consecutive patients diagnosed with probable BAD. All patients were treated within 12 h of symptom onset to prevent clinical progression using dual antiplatelet therapy with cilostazol plus one oral antiplatelet drug (aspirin or clopidogrel). Endpoints of progressive BAD in the dual therapy group at 2 weeks were compared with a matched historical control group of 142 patients treated with single oral antiplatelet therapy using either cilostazol, aspirin, or clopidogrel. Results: Progressive motor paresis occurred in 14 patients (9.7%) in the aggressive antiplatelet group, compared with 48 (33.8%) in the matched single antiplatelet group. Multivariate logistic regression analysis revealed the following variables to be associated with a better prognosis for BAD: baseline modified Rankin Scale score, dual oral antiplatelet therapy with cilostazol, and dyslipidemia (odds ratios of 0.616, 0.445, and 0.297, respectively). Hypertension was associated with a worse prognosis for BAD (odds ratio of 1.955). Conclusions: Our trial showed that clinical progression of BAD was significantly reduced with the administration of ultra-early aggressive combination therapy using cilostazol compared to treatment with antiplatelet monotherapy.
An 18-year-old male presented with a chondroma in the petrous apex manifesting as major complaints of headaches and sensorineural hearing disturbance on the right. Head computed tomography and magnetic resonance imaging revealed a neoplastic lesion in the right petrous apex, which had bulged to compress the internal auditory meatus. Surgical removal improved his hearing with normalization of the postoperative air conduction threshold by reduction of the pressure of the internal auditory meatus, suggesting that the function of the cochlea was retained and the tumor was compressing the cochleal nerve at the level of the internal auditory meatus. Histological examination showed the tumor consisted of hyaline cartilage tissue without cellular atypia and the diagnosis was chondroma.
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.
