Neuroendoscopic and histopathological correlation in 13 cases of cystic fluid filled brain tumours.

Neuroendoscopical images of fluid-filled cavity walls within encephalic tumours in thirteen adult patients were correlated with histopathology results of samples harvested during surgery. Extensive vascular proliferation, with mesh-like formations in a 3D pattern, as well as onionskin appearance, were observed in malignant tumours, as opposed to normal or slightly increased vascular pattern, observed in benign neoplasms. Medical facilities lacking sufficient technical resources where limited pathologist experience is expected, and can be associated with intraoperative histological misdiagnosis.

Endoscopic evidence of ventricular and cisternal inflammatory changes after intraoperative cysticercal rupture during endoscopic third-ventriculostomy removal.

Two patients who suffered recurrent hydrocephalus after cysticercal removal by means of endoscopic transventricular (ETV) approach are presented. Severe inflammatory lesions within the ventricular system and basal cisterns, with a patent third-ventriculostomy were demonstrated during a second endoscopic observation. Mandatory shunting with prolonged steroid therapy may be indicated after intraoperative cysticercal rupture after ETV removal, as showed by sequential endoscopic observations.

Cisternal neurocysticercosis.

Endoscopic third-ventriculostomy followed by removal of multiple cisternal cysts was performed in a patient with hydrocephalus secondary to cisternal cysticercosis. Adjuvant pharmacological therapy with cystocidal drugs and steroids, was administered in the postoperative period.

Role of neuroendoscopy in the treatment of large viable cysticerci in the brain parenchyma.

Neuroendoscopy has never been used for diagnosis-making and removal of large parenchymal viable parasites associated with severe mass effect. Satisfactory and complication-free removal of the parenchymal cysticerci was achieved after neuroendoscopical diagnosis in a patient with parenchymal parasites, with immediate remission of clinical alterations related to raised intracranial pressure.

The impact of neuroendoscopy in the emergency setting--a retrospective study of imaging, intraoperative findings, and surgical outcome in 55 patients.

Objectives: To assess whether neuroendoscopy is an improved and effective diagnostic as well as therapeutic tool in the emergency setting compared with neuroimaging studies.

Patients And Methods: Sixty-two preoperative computed tomography (CT) and magnetic resonance (MR) scans from 55 adult patients admitted in the emergency ward were compared with equal number of neuroendoscopy observations by independent observers, who included cases of raised intracranial pressure related to hydrocephalus, shunt dysfunction, intracranial cysts, brain tumours, subdural effusions, etc.

Results: According to the results obtained, three groups were formed.
