Head injury is a common form of trauma. For example, in the UK head injury occurs in more than 500 000 persons per annum of which about 10% are diagnosed as severe, 15% moderate and the remainder as minor head injury (Miller et al., 1992; Pickard and Czosnyka, 1993). Head trauma is a significant cause of death and disability, especially in young males (median age < 30) and is associated with ra...

We report a case of central neurocytoma that manifested tumor recurrence with craniospinal dissemination. Imaging studies before surgery showed a markedly enhanced tumor with small cysts and calcification, which invaded the adjacent brain parenchyma, located in the posterior horn of the right lateral ventricle. Proton MR spectroscopy showed markedly elevated choline and lactate peaks with a str...

Idiopathic hypertrophic pachymeningitis (IHP) is a rare disease, and it is characterized by chronic progressive inflammatory fibrosis and thickening of the dura mater with resultant compression of the spinal cord or neural structure without any identifiable cause. It can occur in the intracranial or spinal dura mater alone or as a craniospinal form. The spinal form is rarer than the cranial for...

Background: Craniospinal irradiation (CSI) of medulloblastoma poses technological challenges due to the involvement of large treatment volume. Commonly, the whole treatment length is covered with two different isocentric plans in which the junction is shifted after every five fractions to overcome the possibility of hot and cold spot.Objective: This study aims to evaluate dosimetrically and cli...

A patient with an uncommonly situated congenital intradural arachnoid cyst is reported. The cyst extended from the cervical spinal canal into the posterior cranial fossa and was posterolateral to the spinal cord. The patient's initial complaint was urinary hesitancy. The location of the cyst is unique and the presenting complaint rare.

Seventeen neuraxis tuberculoma cases diagnosed and treated at Hacettepe University Medical Central between 1965 and 1988 were reviewed. Thirteen of these patients were explored surgically and all except two who died received anti-tuberculous chemotherapy in the postoperative period. In four patients who received aggressive medical treatment without surgical intervention. this treatment led to r...

Craniospinal irradiation (CSI) using IMRT allows dose sparing to organs-at-risk (OAR) whilst conforming the dose to the target volume. Due to the complexity of treatment involving several isocenters, the dose distribution created by the inverse-planned segmented fields must be verified prior to treatment. We propose and test methods to verify dose delivery using commonly available dosimetry equ...
