Lipomyelomeningocele, a congenital spine defect, is presented as skin-covered lipomatous tissue that attaches to the cord in different ways according to its subtypes. Unlike other types of neural tube defects, the exact cause of this birth defect has not been confirmed yet, but it is proposed to be a multifactorial disease with involvement of both genetic(More)
OBJECTIVE Exophytic gliomas of the medulla are rare childhood tumors that mostly are pilocytic astrocytomas. Here we report our experience in 11 -children with this rare tumor. METHODS A retrospective study was performed using the records of children with exophytic gliomas of the medulla at Children's Hospital Medical Center in Tehran, Iran, from 2002(More)
OBJECTIVE Optic pathway gliomas (OPG) are infrequent pediatric brain tumors that affect the optic nerve and the visual pathway in the brain. A wide spectrum of signs and symptoms, such as visual impairment, nystagmus, proptosis, and visual loss, may occur at different stages. Other manifestations, such as hydrocephalus, diancephalic syndrome, neurologic(More)
Background: This study aimed to investigate the pedicle dimension and angulation in cervicothoracic junction (CTJ) using the findings of computed tomographic (CT) to help accurate insertion of pedicular screw. Methods: Forty three patients with high quality CT images of CTJ were evaluated. Pedicle width (PW), pedicle height (PH), pedicle axis length (PAL),(More)
BACKGROUND In general, it seems that both genetic and environmental factors play important roles in the induction of neural tube defects. Lipomyelomeningocele (LipoMMC) is a rather common type of closed neural tube defect, but only limited studies have investigated the potential risk factors of this anomaly. Therefore, the purpose of this case-control study(More)
A child with a very rare anomaly of spinal cord is described. The patient presented at 9 months of age with trifid cord at thoracolumbar region and extensive split cord malformation (SCM) from T12-L5. She had a composite type SCM including type II at T12-L1 and SCM type I from L2, L3, to L4 levels. The condition seemed to be something like three distinct(More)
Intervertebral disc degeneration (IVDD) is one of the common causes of low back pain. Similar to many other multifactorial diseases, it is affected by environmental and genetic factors. Although not completely understood, genetic factors include a wide spectrum of variations, such as single nucleotide polymorphisms, which could play a significant role in(More)
Intradural sacrococcygeal teratoma (SCT) is a rare entity that has been reported in only a few cases previously. The authors present the case of a 2-week-old, otherwise healthy neonate with a mass in the buttock. The imaging findings and the high level of serum alpha-fetoprotein were highly suggestive of SCT. On operation the authors found intradural(More)
BACKGROUND Brain tumors in infants have different clinical presentations, anatomical distribution, histopathological diagnosis, and clinical prognosis compared with older children. MATERIALS AND METHODS A retrospective analysis was done in patients <12 months old who were operated on for primary brain tumor in Children's Hospital Medical Center since 2008(More)
The Ullrich-Turner syndrome (complete or partial X-chromosome monosomy) has been found to be associated with an increased rate of some extragonadal neoplasms. Sporadic reports of the Turner syndrome with various brain tumors, including few cases of glioblastoma multiforme, have been found in the literature. However, published data are insufficient to(More)
