Posterior fossa oligodendroglioma
The Indian Journal of Pediatrics, 2002Oligodendroglioma are the tumors of glial cells. They are rare in children and are more common in the cerebral hemispheres. A rare case of infratentorial oligodendroglioma in a female child is being reported here.

Surgery of the Posterior Fossa
Otolaryngologic Clinics of North America, 1984The last 20 years have brought many advances in surgical approaches to the posterior cranial fossa as well as improved surgical technique. The purpose in this article has been to describe the commonly used approaches and to discuss the major advantages and disadvantages.

Posterior fossa haemangioblastomas
Acta Neurochirurgica, 199436 consecutive years' experience in treating 104 cases of posterior fossa haemangioblastomas is described and discussed. The mortality was 24%, with a tendency to decrease, reaching 20% in the last 15 years. About half the patients returned to neurological normality and full working capacity.

A case is reported of a ceruminoma invading through the petrous temporal bone and meninges and into the cerebellum and brain stem. The tumour presented initially as a progressive facial palsy and later involved other cranial nerves. The poor prognosis and the importance of early recognition and radical treatment of this tumour is emphasized.

Meningiomas of the posterior fossa
Surgical Neurology, 1983Clinical and surgical results in 38 cases of posterior fossa meningiomas are presented. All cases have been diagnosed and operated upon during the last 12 years in this department. We have identified five locations for these tumors: cerebellopontine angle, cerebellar convexity, tentorium, peritorcular, and clivus.

Pediatric brain tumors are the leading cause of death from solid tumors in childhood. The most common posterior fossa tumors in children are medulloblastoma, atypical teratoid/rhabdoid tumor, cerebellar pilocytic astrocytoma, ependymoma, and brainstem glioma.

Posterior fossa hemangioblastomas
Surgical Neurology, 1986The authors report 40 personal cases of infratentorial hemangioblastomas and review 36 series from the literature for a total number of 1023 patients. The clinical, pathological, and surgical features of these tumors are discussed, with particular consideration of localizations outside the nervous system, multicentric tumors, recurrences, and long-term

This article discusses the normal anatomy of the posterior fossa structures followed by a discussion of the characteristic neuroimaging features of a variety of cerebellar and brainstem malformations. In this context, the authors classify posterior fossa malformations based on the neuroimaging pattern into (1) predominantly cerebellar, (2) cerebellar ...

Posterior fossa measurements I. The normal size of the posterior fossa
Pediatric Radiology, 1978The posterior fossa area was defined as that situated below Twining's line while the one above was called the supratentorial area. A ratio has been calculated: Posterior fossa area/Supratentorial area X 100 = posterior fossa ratio. Above 7 years this was (mean) 16.5% +/- 2 and below 7 years 14.0% +/- 4, with the ranges (13.2-20.2) and (9.0 - 19.4 ...

Understanding embryologic development of the cerebellum and the 4th ventricle is essential for understanding posterior fossa malformations. Posterior fossa malformations can be conveniently classified into those that have a large posterior fossa and those with normal or small posterior fossa.
