    Metastasis of an atrial myxoma to the brain is extremely rare. Thus far there are only 17 cases reported, including our present case. Most of the brain metastases manifest only in 3 to 6 decades, after an average time frame of one to two years after surgical removal of parental tumour. We present a case of brain metastases of atrial myxoma in a teenager of the youngest age among all reported cases, unusually as early as 15 years old. The progress of the metastatic process had been insidious for three years after heart surgery, The imaging demonstrated a rather sizeable tumour by the time when the patient is symptomatic. The location of the metastatic tumour is anyhow superficial to the cortical surface, enabling complete surgical excision of the tumour easily achievable with favourable outcome.

    Two hundred primary brain tumours in both adults and children from the year 1990 to 1998 presenting for treatment to the Neurosurgical Division of the Hospital of the University of Sciences Malaysia were studied retrospectively. Volumes of tumours were taken from CT scans with contrast using two formulas and divided into 4 groups: (1) less than 20 cm(3), (2) 20-50 cm(3), (3) 50-100 cm(3) (4) larger than 100 cm(3). The majority of the brain tumours were in the volume range of 50-100 cm(3), and are thus potentially curable with retroviral gene therapy.

    Rhabdoid tumour is a rare childhood tumour with poor prognosis. We report a 13-month-old Malay girl suffering from this tumour that was located at the left fronto-temporo-parietal region of the brain. Computed tomography showed a large irregular enhancing mass that caused obstructive hydrocephalus. The tumour did not reduce in size after three operations and finally the patient succumbed to the disease four months after diagnosis.

    The advent of multimaterial 3D printers allows the creation of neurosurgical models of a more realistic nature, mimicking real tissues. The authors used the latest generation of 3D printer to create a model, with an inbuilt pathological entity, of varying consistency and density. Using this model the authors were able to take trainees through the basic steps, from navigation and planning of skin flap to performing initial steps in a craniotomy and simple tumor excision. As the technology advances, models of this nature may be able to supplement the training of neurosurgeons in a simulated operating theater environment, thus improving the training experience.

    Two rare cases of intractable epilepsy caused by Dysembryoplastic Neuroepithelial Tumours (DNET) are reported and their different management discussed. The first case required vagal nerve stimulation and radiosurgery while the later was operated with the help of neuronavigation. Both had good outcome according to Engel classification after a one year follow up.

    From 1973 to 1984, 119 patients presented to the Department of Neurosurgery, Royal Victoria Hospital, Belfast, with brain metastases, the primary sites of which remained unknown in 33 cases one month after discharge. About half of these cases were solitary and neurological lateralising signs were the commonest presentation. Of those cases in which surgery was performed, the majority remained improved one month after surgery. The one month mortality rate was only 3%. This study shows that with aggressive and appropriate treatment including surgical excision or decompression in solitary cases, an improved quality of life in the immediate postoperative period can be achieved in this particular group of brain metastases. A small number of patients remained alive and well after 6 months.

    Resection of brain tumors is a tricky task in surgery due to its direct influence on the patients' survival rate. Determining the tumor resection extent for its complete information via-à-vis volume and dimensions in pre- and post-operative Magnetic Resonance Images (MRI) requires accurate estimation and comparison. The active contour segmentation technique is used to segment brain tumors on pre-operative MR images using self-developed software. Tumor volume is acquired from its contours via alpha shape theory. The graphical user interface is developed for rendering, visualizing and estimating the volume of a brain tumor. Internet Brain Segmentation Repository dataset (IBSR) is employed to analyze and determine the repeatability and reproducibility of tumor volume. Accuracy of the method is validated by comparing the estimated volume using the proposed method with that of gold-standard. Segmentation by active contour technique is found to be capable of detecting the brain tumor boundaries. Furthermore, the volume description and visualization enable an interactive examination of tumor tissue and its surrounding. Admirable features of our results demonstrate that alpha shape theory in comparison to other existing standard methods is superior for precise volumetric measurement of tumor.

    Coagulation factor XIII and other haemostatic markers are known strengthen fibrin clot formation and, hence, may facilitate safer surgery. Currently however, factor XIII activity levels are not routinely screen. Therefore, the purpose of this study was to determine the association of perioperative factor XIII activity levels and other haemostatic markers with postoperative intracranial haematoma formation in neurosurgical patients.

    This is a descriptive epidemiologic study that was done retrospectively for the years 1990-1996. The objective was to determine whether tumours less than 4 cm in diameter are common and thereafter suitable for radiosurgical treatment. The results showed that the incidence of brain tumours less than 4 cm in diameter was 73.3% and about 20% were situated in the eloquent area.

    BACKGROUND: Whole brain radiotherapy (WBRT) and stereotactic radiosurgery were frequently used to palliate patients with brain metastases. It remains controversial which modality or combination of therapy is superior especially in the setting of limited number of brain metastases. The availability of newer medical therapy that improves survival highlighted the importance of reducing long term radiation toxicity associated with WBRT. In this study, we aim to demonstrate the hippocampal sparing technique with whole brain and integrated simultaneous boost Materials and Methods: Planning data from 10 patients with 1-5 brain metastases treated with SRS were identified. Based on the contouring guideline from RTOG atlas, we identified and contoured the hippocampus with 5mm isocentric expansion to form the hippocampal avoidance structure. The plan was to deliver hippocampal sparing whole brain radiotherapy (HSWBRT) of 30 Gy in 10 fractions and simultaneous boost to metastatic lesions of 30 Gy in 10 fractions each.

    RESULTS: The PTV, hippocampus and hippocampal avoidance volumes ranges between 1.00 - 39.00 cc., 2.50 - 5.30 cc and 26.47 - 36.30 cc respectively. The mean hippocampus dose for the HSWBRT and HSWBRT and SIB plans was 8.06 Gy and 12.47 respectively. The max dose of optic nerve, optic chiasm and brainstem were kept below acceptable range of 37.5 Gy.

    CONCLUSIONS: The findings from this dosimetric study demonstrated the feasibility and safety of treating limited brain metastases with HSWBRT and SIB. It is possible to achieve the best of both worlds by combining HSWBRT and SIB to achieve maximal local intracranial control while maintaining as low a dose as possible to the hippocampus thereby preserving memory and quality of life.

    We reported a case of orbital rhabdomyosarcoma with an intracranial extension in an HIV-infected child. It was an uncommon sarcoma in a retroviral-positive patient that resulted in a diagnostic and therapeutic dilemma. The child is currently asymptomatic following surgery, chemotherapy, and reinstitution of highly active retroviral therapy (HAART).

    We report a 33-year-old Chinese gentleman who presented with visual epilepsy and symptoms of raised intracranial pressure in which clinical examination revealed normal visual fields and acuity despite Magnetic Resonance Imaging (MRI) brain showing large contrast enhancing mass at the right occipital lobe. Craniotomy and excision of tumour was done and the histology confirmed glioblastoma multiforme (GBM). He completed radiotherapy and recovered well except developing left inferior homonymous quadrantropia post operatively which improved with time.

    Strongyloidiasis is an infection caused by the intestinal nematode Strongyloides stercoralis. Infected healthy individuals are usually asymptomatic, however it is potentially fatal in immunocompromised hosts due to its capacity to cause an overwhelming hyperinfection. Strongyloidiasis could be missed during routine screening because of low and intermittent larval output in stool and variable manifestations of the symptoms. We present two cases of strongyloidiasis occurring in children with solid organ malignancies suspected to have the infection based on their clinical conditions and treatment history for cancer. Both patients were diagnosed by molecular and serological tests and were successfully treated. Thus, strongyloidiasis in patients undergoing intensive treatment for malignancies should be suspected, properly investigated and treated accordingly.

    Alteration of the tumor suppressor gene p53 is considered to be a critical step in the development of human cancer. Changes in this gene have been detected in a wide range of human tumours, including gliomas. In glioma, the presence of p53 gene alterations has been associated with worse prognosis.
