OBJECTIVE AND IMPORTANCE Presacral meningocele in hereditary sacral agenesis is a complex and unusual spinal dysgenetic syndrome. Recognition of the syndromic triad, its natural history, and familial presentation has important practical applications for the management of this disease as well as its complications. CLINICAL PRESENTATION This report concerns(More)
Intraorbital schwannoma is a rare tumor that constitutes approximately 1%-8% of all orbital tumors. The authors report a case of orbital schwannoma in a 5-year-old boy who was admitted to their institute with exophthalmos and ptosis of the right eye. Computed tomography scanning and MR imaging revealed a retroocular mass in the right orbit. The tumor was(More)
It is extremely rare for metastasised medulloblastoma to form a large tumour in the suprasellar region. We present a case of medulloblastoma with large suprasellar metastasis at initial presentation. A 3-year and 5-month-old boy presented with a 1-month history of vomiting and loss of appetite, and body weight. Computed tomography and magnetic resonance(More)
PURPOSE Various treatment modalities have been used in the management of chronic subdural hematoma and subdural hygroma (CSDH/SDHy) in children. However, few studies have examined burr-hole craniotomy without continuous drainage in such cases. Here, we retrospectively evaluated the efficacy and safety of burr-hole craniotomy without continuous drainage for(More)
Pick's disease is a type of frontotemporal lobar degeneration(FTLD) with circumscribed atrophy in the frontotemporal lobe. The terminology for Pick's disease has evolved over time. Pick's disease was a term formerly used to define a disorder with symptoms caused by frontal and temporal lobe dysfunction. Therefore, the diagnosis was previously based on(More)
BACKGROUND Choroid plexus papilloma (CPP) in the third ventricle is a rare benign intracranial tumor. METHODS We report 3 pediatric cases of CPP in the third ventricle. The lesions were totally removed by a different surgical approach in each case. RESULTS When remarkable hydrocephalus is present, the transcortical approach is easier to perform, but may(More)
The treatment of spinal abnormalities with cloacal exstrophy is controversial. Ten cases of this complex treated at Hyogo Prefectural Kobe Children's Hospital between 1991 and 2010 are presented. In our series, all 10 patients had tethered spinal cords. In addition, there were 3 terminal myelocystoceles, 2 meningoceles, 7 lipomas, 5 thickened filums and 3(More)
A 5-month-old boy presented with a rare case of intramedullary teratoma extending from T1 to S5 and associated with a lumbosacral lipoma. Magnetic resonance imaging showed the tumor extended over the lipoma. Since the tumor could not be clearly demarcated from the spinal cord, surgery was performed under a preoperative diagnosis of spinal glioma. The lack(More)
We describe the treatment of patients having syndromic craniosynostosis with severe craniofacial abnormality. One patient had Cruzon's syndrome, one had Beare-Stevenson cutis gyrata syndrome, and four had Pfeiffers syndrome. Anterior cranial deformity in all patients was treated using fronto-orbital advancement (FOA) by gradual distraction. Initially, the(More)
Intracranial capillary hemangiomas are very rare, though several spinal capillary hemangiomas have recently been reported. We report here a case of intracranial capillary hemangioma with multiple cysts and review the current literature of similar cases. A 4-month-old girl was referred to our hospital for treatment of hydrocephalus and a cerebellar mass(More)
