Neuroendoscopic procedures with a flexible fiberscope for the removal of IVH allow resolution of the disturbed CSF circulation. This procedure improves the safety and accuracy of treatment for IVH combined with hydrocephalus.
A 39-year-old woman presented with long-standing overt ventriculomegaly in adults (LOVA) manifesting as gradually worsening headache. Past history included treatment for myeloschisis at birth. Intelligence quotient (IQ) was 115 and preoperative psychological assessment using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) showed normal scores in all domains. However, scores for constructional ability were slightly low. Computed tomography revealed severe ventriculomegaly involving the lateral and third ventricles, and magnetic resonance imaging showed aqueductal stenosis. Endoscopic third ventriculostomy was performed under a diagnosis of LOVA. Postoperatively, the headache resolved and the RBANS showed improvements in memory and constructional ability. Detailed evaluation of cognitive function provides a good indicator in the treatment of hydrocephalus with normal IQ.
✓The authors report on a rare case of pilomyxoid astrocytoma in a patient presenting with fatal hemorrhage. This 5-year-old boy presented to the outpatient clinic with headache and vomiting. Computed tomography and magnetic resonance imaging studies revealed a mass lesion with partial hemorrhage in the suprasellar region extending into the third ventricle. Partial resection via a transcallosal approach was performed. Because the pathological diagnosis was pilomyxoid astrocytoma, chemotherapy was administered. However, 4 months after the first operation, during chemotherapy, the boy presented with massive intratumoral and intraventricular hemorrhage with hydrocephalus. Although emergent external ventricular drainage was performed, the patient died. In this report, the authors review the literature and discuss the clinical features and treatment of pilomyxoid astrocytoma.
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.
