A 30-year-old multigravida woman was admitted to the obstetrical unit in the third trimester of gestation, because of a large-for-date uterus. Repeated ultrasonic examinations over a 2-week period revealed an increase in biparietal diameter far too large to be normal. This progressive asymmetrical hydrocephalus was diagnosed as caused by an intracranial space-occupying lesion in the middle cranial fossa. Because of the only minimal thickness of the cerebral cortex prognosis was judged so poor, that labor was induced. A stillborn female infant was delivered vaginally after an ultrasonically guided transabdominal and later transcervical encephalocentesis. Autopsy revealed hydrocephalus and section through the fixed brain showed that the mentioned mass was an undifferentiated meningeal sarcoma that filled the left middle cranial fossa. Microscopically the sarcoma was invading the brain tissue. Definitions of the term "congenital brain-tumors" vary among authors. "Congenital" can be interpreted as "derived from embryonal tissue" or as "originating in utero". Congenital intracranial neoplasms are very rare. Antenatally intracranial tumors have been reviewed by Wells, Solitare and Farwell. Only a few cases of congenital brain tumors arising in the meninges have been reported in these reviews. The genesis of the tumor is explained as derived from multipotential cells. The undifferentiated type of a meningeal sarcoma has a poor prognosis. Most meningeal sarcoma present with progressive hydrocephalus.(ABSTRACT TRUNCATED AT 250 WORDS)

Optical coherence tomography (OCT) has proved to be a very valuable tool in the assessment of patients with glaucoma. In this report, intracranial tumors were discovered in two glaucoma suspects referred for diagnostic confirmation by OCT - a clivus chordoma and a craniopharyngeoma. Optical coherence tomography findings - marked asymmetrical diffuse attenuation of the peripapillary nerve fiber layer in nasal and temporal sectors - raised concerns about lesions in chiasmatic region and permitted the timely diagnosis of these intraocular tumors.

Vestibular schwannomas (VS) comprise 8% of all intracranial tumors and 90% of cerebellopontine angle and internal auditory canal neoplasms. Secondary to the widespread adoption of screening protocols for asymmetrical hearing loss and the increasing use of advanced imaging, the number of VS diagnosed each year continues to rise, while the average size has declined. Microsurgery remains the treatment of choice for large tumors, however the management of small- to medium-sized VS remains highly controversial with options including observation, radiotherapy, or microsurgery. Within this chapter, the authors provide an overview of the contemporary management of VS, reviewing important considerations and common controversies.
