BACKGROUND Ewing's sarcomas account for approximately 10% of primary malignant bone tumors. While most of the primary Ewing's sarcomas occur in the long bones, pelvis, or ribs, approximately 1-6% of these sarcomas arise in the skull. We found approximately 50 cases of Ewing's sarcoma of the calvarium reported in our search of the literature. Of these, 36(More)
Mycobacterium avium complex (MAC) infection causes disseminated disease in immunocompromised hosts, such as human immunodeficiency virus (HIV)-positive patients, and pulmonary disease in persons without systemic immunosuppression, which has been increasing in many countries. In Japan, the incidence of pulmonary MAC disease caused by M. avium is about 7(More)
CASE REPORT We present a case of solitary myofibromatosis of the skull in a 4-year-old girl. Surgery was performed and the final diagnosis of myofibromatosis was made histopathologically. DISCUSSION Solitary myofibromatosis of the skull is rare and we found approximately 20 reported cases in the English-language literature. We reviewed eight(More)
INTRODUCTION While raised intracranial pressure (ICP) is a well recognized complication affecting children with syndromic craniosynostosis, certain percentage of the patients with non-syndromic craniosynostosis may have some problems related to increased ICP, such as developmental delay or visual problem. However, it is still not clear how many percent of(More)
Mycobacterium avium complex (MAC) causes mainly two types of disease. The first is disseminated disease in immunocompromised hosts, such as individuals infected by human immunodeficiency virus (HIV). The second is pulmonary disease in individuals without systemic immunosuppression, and the incidence of this type is increasing worldwide. M. avium subsp.(More)
The management of posthemorrhagic hydrocephalus is difficult and not well standardized. We evaluated our management protocol for infants with intraventricular and/or periventricular hemorrhage (IVH and PVH, respectively). There were four deaths and two significant treatment-related complications in our series. We also observed two cases of isolated(More)
INTRODUCTION Hydrocephalus does not indicate a single clinical entity, but includes a variety of clinicopathological conditions caused by excessive cerebrospinal fluid (CSF) based on the disturbed circulation. Recent progress in prenatal neuroimagings such as MRI and ultrasound echoencephalography on fetus enables to understand clinicopathological(More)
We report two infant cases with atypical teratoid/rhabdoid tumor (AT/RT) located in the cerebellar vermis and spinal cord. MRI showed the tumors were isointense on T1-weighted images and mixed intensity of isointense and slight high intensity on T2-weighted images. Postcontrast MRI demonstrated clear margin of tumor and heterogeneous strong enhancement. It(More)
