Abstract The results of endoscopic biopsy in 21 cases of intraventricular tumor are presented. The details of the equipment are given. Of the 21 tumors biopsied, there were 9 in the lateral ventricle, 2 in the thalamus, 6 in the anterior portion of the 3rd ventricle, and 4 in the pineal region. A correct histological diagnosis was made in 11 cases (52.4%). No serious complications were noted. The value of the procedure is discussed.

Abstract This report describes two cases of craniopharyngioma with perifocal edema. In both patients, computed tomography and magnetic resonance imaging (MRI) revealed that the tumors occupied the suprasellar cistern, invaginated the floor of the 3rd ventricle and were tightly adherent to the ventricular walls. The intraventricular portions of the tumors were cystic, containing protein-rich fluid as suggested by MRI and confirmed by operative findings. There was perifocal edema in the hypothalamus adjacent to the intraventricular tumor, the optic tracts, and the posterior limbs of the internal capsules, resembling the shape of a moustache on axial computed tomographic and MRI scans. The perifocal edema subsided after treatment of the intraventricular tumor by surgical resection or radiation therapy. The “moustache” appearance seems a unique, characteristic feature of perifocal edema, which is observed infrequently with certain craniopharyngiomas.

Neurocytomas are typically intraventricular in location, and extraventricular neurocytomas are uncommon. The authors report the unique case of a 15-year-old girl who was found to have a low-grade neurocytoma infiltrating the brainstem and cerebellum and spreading along the CSF pathways to the lateral and third ventricles. The patient underwent endoscopic third ventriculostomy to treat associated hydrocephalus, and biopsy specimens from intraventricular tumor nodules were obtained. Because of the low-grade pathology, the fact that the lesion was not amenable to resection, and the extensive radiation field required for radiation therapy, she has been treated conservatively with close follow-up. Over the course of almost 4 years since diagnosis, no additional treatment has been required. Neurocytoma with widespread infiltration of the brainstem and cerebellum has not been previously reported.

✓Several neurosurgical studies have provided descriptions of the utility of fluorescence-guided tumor resection using a microscope. However, fluorescence-guided endoscopic detection of a deep-seated brain tumor has not yet been reported. The authors report their experience with an endoscopic biopsy procedure for a malignant glioma within the third ventricle using a 5–aminolevulinic acid (5-ALA)–induced protoporphyrin IX fluorescence imaging system. A 5-ALA–induced fluorescence image of an intraventricular tumor is barely visible with the typical fluorescence endoscopic system used in other clinical fields because the intensity of excitation light at wavelengths of 390 to 405 nm through a cutoff filter is too weak to delineate a brain tumor. The technique described in this study made use of a laser illumination system with a high-powered output that delivered a violet-blue light at wavelengths of 405 nm. In addition, a common ultraviolet cutoff filter was fitted between the endoscope and the high-sensitivity camera to block the backscattered excitation light. A 5-ALA–induced fluorescence endoscopy performed using this system allowed the intraventricular tumor to be clearly visualized as a red fluorescent lesion. Several biopsy specimens obtained from the fluorescent lesion provided a definitive histological diagnosis. The results indicate that this endoscopic system is useful in detecting an intraventricular fluorescent tumor.
