The sylvian aqueduct is the most common site of intraventricular blockage of the cerebro-spinal fluid. Clinical aspects, neuroradiological appearance, and treatment of hydrocephalus secondary to aqueductal stenosis are specific. An extensive literature review concerning etiologic, pathogenetic, clinical, and neuroradiological aspects has been performed.(More)
Even if the first description of Dandy–Walker dates back 1887, difficulty in the establishment of correct diagnosis, especially concerning differential diagnosis with other types of posterior fossa CSF collection, still persists. Further confusion is added by the inclusion, in some classification, of different malformations with different prognosis and(More)
BACKGROUND Endoscopic third ventriculostomy (ETV) is the treatment of choice for noncommunicating hydrocephalus. In the last decade, its routine use also has taken place in patients who have previously undergone shunt placement (secondary ETV). METHODS This study reviews the specific anatomy of the ventricular system in patients presenting with shunt(More)
Gangliogliomas originating in the optic pathway are rare, with less than 20 cases reported in the literature. Diffuse, bilateral involvement of the entire optico-chiasmatic pathway is exceptional. We report a case of suprasellar ganglioglioma that involved bilaterally the entire pregeniculate optic pathway. The patient presented with visual deficit,(More)
OBJECTIVE In the past, the outcome of surgical treatment for thalamic tumor was poor. These lesions were often considered inoperable. However, contemporary microsurgical techniques, together with improvements in neuroimaging that enable accurate presurgical planning, allow resection to be accomplished in a safer way. METHODS The medical records, imaging(More)
Central nervous system (CNS) complications during treatment of childhood acute lymphoblastic leukemia (ALL) remain a challenging clinical problem. Outcome improvement with more intensive chemotherapy has significantly increased the incidence and severity of adverse events. This study analyzed the incidence of neurological complications during ALL treatment(More)
Infants affected by neuroblastoma with symptomatic epidural compression require early diagnosis and appropriate treatment to avoid severe late complications. However, no established guidelines are available regarding the optimal treatment of these patients. We describe 5 such infants. The interval between the onset of symptoms and tumor diagnosis was 3 to 8(More)
OBJECTIVE Intraventricular choroid plexus cysts are unusual causes of acute hydrocephalus in children. Radiological diagnosis of intraventricular choroid plexus cysts is difficult because they have very thin walls and fluid contents similar to CSF and can go undetected on routine CT studies. METHODS This study reports the authors' experience with 5 patients(More)
