Melanocytoma is a rare benign lesion arising from leptomeningeal melanocytes. Meningeal melanocytomas are commonly seen in the thoracic region of the spinal canal and may also arise in the cervical or lumbar region, most often located in the intradural extramedullary compartment 1. To our knowledge, only 21 cases of intramedullary melanocytomas have been reported in the literature to date. The authors present a rare case of thoracic intramedullary melanocytoma and the review of the literature pointing out the role of diagnosis, surgical treatment and follow-up. 折りたたむ

Multi-modality therapy has led to significant improvement in outcomes for childhood medulloblastoma; however, long-term survivors have become more susceptible to late effects of therapy including induction of second malignant neoplasms and even remain at an increased risk of late relapses including extra-neuraxial metastases. A newly detected solitary lytic/sclerotic osseous lesion in a medulloblastoma survivor away from the radiation field poses considerable diagnostic challenge as it could represent either a second malignant neoplasm or extra-neuraxial metastasis. We report one such case highlighting the importance of contemporary pathology techniques as useful adjuncts to differentiate a second primary osseous Ewing’s sarcoma (ES)/primitive neuro-ectodermal tumor (PNET) from bony metastasis and review the pertinent literature on second malignant neoplasms and extra-neuraxial metastases in medulloblastoma. To the best of our knowledge, this is the first report of a molecularly confirmed second primary osseous ES/PNET in a survivor of childhood medulloblastoma. 折りたたむ

Pituitary abscess is extremely rare and often misdiagnosed as pituitary tumor pre-operatively. We document a case of a 64-year-old lady presented to the outpatient department with complaints of headache and blurring vision of right eye for one month. Based on preliminary investigations, a clinical diagnosis of pituitary adenoma was made and the pituitary gland was surgically excised. Histopathological examination showed Actinomyces infection. This case has been documented due to the extremely rare involvement of the pituitary gland by actinomyces infection. Pituitary abscess is a rare pathology, but it must be considered during evaluating sellar masses, since its prognosis depends on surgical drainage and on the use of specific antibiotics. We report, to our knowledge, the fourth case of Actinomyces israelii infection of the pituitary region. 折りたたむ

Background: Spontaneous primary intracranial hemorrhage or known as intracerebral hypertensive hemorrhage consist of 15 to 20% of all stroke, is one of the major health problems among healthy and productive workforce in any countries. Methods: A retrospective study was conducted in a dedicated Neurosurgical Centre at the Hospital Sungai Buloh, Malaysia. The study was conducted for admission within a year period, in the year 2013 with 6 months follow-up. A total of 35 patients were studied. Results: The mean age was 52.8 years old (31-77 years old). A total of 29 patients (82.9%) were presented with basal ganglia hemorrhage, 4 with cerebral lobar hemorrhage (11.4%) and 2 with cerebellar hemorrhage (5.7%). The surgical mortality rate was 40%. For the 6 months follow-up, 31.4% patients improved to Glasgow Outcome score (GOS) of 4, while 22.9% and 5.7% patients improved to only GOS of 3 and 2 respectively. There were several factors identified in the study to be important predictors of survival. There were statistically significance of higher mortality rate among patients with pre-operative GCS of 5 and below (p=0.015), pre-operative CT scan brain showing acute hydrocephalus (p=0.046) and residual post-operative hematoma above 5% of pre-operative clots volume (p=0.006). Other factors such as age, sex, size of pre-operative hematomas, presence of intraventricular hemorrhage, underlying medical illness were not statistically significant in predicting the surgical outcome of those patients. Conclusions: Outcome predictors such as pre-operative GCS and CT scan brain findings helps treating neurosurgeons to determine the prognosis of patients presented with spontaneous intracranial hemorrhage. 折りたたむ
