A case of an enterogenous cyst located in the cerebellopontine angle cistern is presented. These cysts have usually been found in the spinal canal, and their intracranial occurrence is exceptional. In the present case, the cyst was lined histologically by a single epithelial layer of cuboidal cells with some glandular structures resembling the fundic glands of the stomach. The unusual location of the cyst and its histological features are discussed.
We report a case of intracranial dissemination developing approximately 6 months after partial removal of a spinal cord astrocytoma in a 40-year-old male. The clinical course and postmortem findings indicate that the tumor originated in the cervical cord and extended into the subarachnoid space, first the spinal canal and later intracranially. Spinal cord glioma dissemination through the cerebrospinal fluid is more common than previously considered and indicates a dismal prognosis. An aggressive approach, including radical surgery, entire neuraxis irradiation, and adjuvant chemotherapy, is suggested as the initial treatment for malignant spinal cord glioma to prevent subsequent dissemination.
Postoperative long-term preservation of hearing is more likely if surgery is performed while the tumor is still small and hearing is still excellent. Under these circumstances, it is more likely that the early and late hearing loss will be compensated.
12 cases of unilateral labyrinthectomy, 3 cases of VIIIth nerve section, 22 cases of streptomycin sulfate infusion into the middle ear cavity and 8 cases of bilateral vestibular a-functions underwent vestibular training. Our training is very useful for regaining equilibrium and for evaluating the effects of training on equilibrium by recording the gravity center movements.
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.
