BACKGROUND: Congenital cranial bone defects predispose to herniation of meninges, sometimes with brain tissue involvement, to form a cerebrospinal fluid (CSF)-filled cyst in the head. Such defects mainly results from focal failure of neural tube closure during fetal development and has been reported in various species of domestic mammals. CASE PRESENTATION: A one week old Ayrshire calf with a fluctuant swelling on parieto-occipital region of the head was referred to the faculty...

INTRODUCTION: Craniosynostosis is the premature fusion of one or more of the cranial sutures and can occur as part of a syndrome or as an isolated defect. Pansynostosis is a rare form of craniosynostosis that involves premature fusion of all the cranial sutures (coronal, sagittal, metopic, and occipital). Particularly in cases of late presentation, there are heightened clinical concerns, both functional and aesthetic. In untreated cases of pansynostosis and increased intracranial pressure, optic nerve damage progresses to optic atrophy and then blindness...

PURPOSE: Radiation protection regulatory differentiates between primary and scatter radiation. Whereas for conventional clinical linear accelerators the solid angle for primary radiation is planar, the Cyberknife (Accuray Inc., Sunnyvale, CA) may point its beam in all spatial directions. In order to be able to judge on radiation protection calculations for a Cyberknife-M6 vault, the direction distribution for delivered plans was evaluated based on clinical experiences. METHODS: The log-files of 121 delivered patient treatment plans were exported, divided into cranial and extra-cranial treatments and the delivered monitor units (MU) together with the corresponding beam directions were analyzed...

Post-mortem interval (PMI) estimation is an important issue in forensic medicine, particularly for criminal purposes and legal limitation periods. The goal of the present study is to examine the evolution of the trabecular cranial vault bone after 4 weeks of conservation in a controlled environment with micro-tomography (μCT) analyses.Four bone samples were extracted from a fresh human cranial vault (a donation to science according to the French law) and conserved in an air-controlled environment. The samples were weighed and μCT scanned at a 10-μm resolution every week after death for a month...

Intentional cranial deformations (ICD) were obtained by exerting external mechanical constraints on the skull vault during the first years of life to permanently modify head shape. The repercussions of ICD on the face are not well described in the midfacial region. Here we assessed the shape of the zygomatic bone in different types of ICDs. We considered 14 non-deformed skulls, 19 skulls with antero-posterior deformation, nine skulls with circumferential deformation and seven skulls with Toulouse deformation...

Correction of orbito-frontal defects involves a multitude of surgical challenges, and requires careful and detailed planning. In the trauma setting, one must be prepared to deal with injuries to adjacent structures and be able to incorporate their repair into the surgical plan to maximize the functional and esthetic reconstruction for the benefit of the patient. Victims who have sustained trauma of the cranial complex in combination with mid-facial trauma, particularly involving the orbit, present a difficult scenario, especially when future ocular prosthetic rehabilitation is a concern...

Standard treatment of primary and metastatic brain tumours includes high-dose megavoltage-range radiation to the cranial vault. About half of patients survive >6 months, and many attain long-term control or cure. However, 50-90% of survivors exhibit disabling cognitive dysfunction. The radiation-associated cognitive syndrome is poorly understood and has no effective prevention or long-term treatment. Attention has primarily focused on mechanisms of disability that appear at 6 months to 1 year after radiotherapy...

Extremely thick cranial vaults have been noted as a diagnostic characteristic of Homo erectus since the first fossil of the species was identified, but relatively little work has been done on elucidating its variation within extant non-human primates. Cranial vault thickness (CVT) is not a monolithic trait, and the relationship of its layers to other morphological variables is unknown. Total CVT and the thickness of the cortical and diploë layers individually, as well as the ratio between diploë and total thickness, were calculated from 258 female individuals from 47 species of non-human primate...

Hyaenodonta is a diverse, extinct group of carnivorous mammals that included weasel- to rhinoceros-sized species. The oldest-known hyaenodont fossils are from the middle Paleocene of North Africa and the antiquity of the group in Afro-Arabia led to the hypothesis that it originated there and dispersed to Asia, Europe, and North America. Here we describe two new hyaenodont species based on the oldest hyaenodont cranial specimens known from Afro-Arabia. The material was collected from the latest Eocene Locality 41 (L-41, ∼34 Ma) in the Fayum Depression, Egypt...

When forensic pathologists and anthropologists have to deal with the evaluation of the post-mortem interval (PMI) in skeletal remains, luminol testing is frequently performed as a preliminary screening method. However, the repeatability of this test on the same bone, as well as comparative studies on different bones of the same individual, has never been performed. Therefore, with the aim of investigating the influence that different types of bones may exert on the response to the luminol test, the present study analysed three different skeletal elements (femoral diaphysis, vertebra and cranial vault), gathered from ten recent exhumed skeletons (all with a 20-year PMI)...

Neural tube defects are a group of congenital anomalies of brain development that carry a significant risk of morbidity and mortality. Anencephaly is a serious form of this defect with a very poor prognosis. It can present in three forms - meroanencephaly, holoanencephaly, and craniorachischisis. Meroanencephaly is considered to be the classic form of anencephaly. It manifests as a lack of cranial vault bones and exposed dorsal neural tissue resulting from defective neural tube closure in the very early period of gestation...

Bones of the cranial vault appear to be highly conserved among tetrapod vertebrates. Moreover, bones identified with the same name are assumed to be evolutionarily homologous. However, recent developmental studies reveal a key difference in the embryonic origin of cranial vault bones between representatives of two amniote lineages, mammals and birds, thereby challenging this view. In the mouse, the frontal is derived from cranial neural crest (CNC) but the parietal is derived from mesoderm, placing the CNC-mesoderm boundary at the suture between these bones...

PURPOSE: We test the hypothesis that ventriculoperitoneal (VP) shunt insertion significantly increases contralateral positional plagiocephaly. METHODS: We reviewed 339 children who had a VP shunt inserted at Birmingham Children's Hospital between 2006 and 2013, noting laterality of shunt insertion and frontal or occipital position. We ascertained the presence of post-operative positional plagiocephaly using the cranial vault asymmetry index. Multinomial logistic regression modelling was used to examine relationships between plagiocephaly, shunt position, gender and age...

BACKGROUND: Resorbable plating in cranial reconstruction for craniosynostosis has fewer reported complications than rigid hardware. Few long-term outcome studies exist for pediatric patients treated with this technology for cranial vault reconstruction. METHODS: A retrospective review was performed on pediatric patients undergoing cranial vault reconstruction for craniosynostosis by 3 surgeons over a 15-year period. MacroPore (Cytori Therapeutics, San Diego, CA) or Lactosorb (Walter Lorenz Surgical Inc, Jacksonville, FL), composed of polyglycolic and polylactic acids, was used for resorbable plate fixation...

Using morphological, histological, and TEM analyses of the cranium, we provide a detailed description of bone and suture growth in zebrafish. Based on expression patterns and localization, we identified osteoblasts at different degrees of maturation. Our data confirm that, unlike in humans, zebrafish cranial sutures maintain lifelong patency to sustain skull growth. The cranial vault develops in a coordinated manner resulting in a structure that protects the brain. The zebrafish cranial roof parallels that of higher vertebrates and contains five major bones: one pair of frontal bones, one pair of parietal bones, and the supraoccipital bone...

BACKGROUND: Incidental findings on brain MRI may constitute a diagnostic pitfall. We observed an incidental extra-axial midline rounded pseudomass between the torcular Herophili and the occipital squama, with spontaneous resolution, which we called "torcular pseudomass." OBJECTIVE: We investigated the frequency, imaging features, natural history and developmental background of this finding in a large group of infants and young children. MATERIALS AND METHODS: We conducted a single-center retrospective study by reviewing all brain MRIs performed in children younger than 3 years between 2007 and 2013 in a specialized pediatric hospital...

INTRODUCTION: Patients with multisutural or single craniosynostosis, often suffer from Chiari malformation and syringomyelia. The surgical management of syringomyelia in these patients is controversial. CASE REPORT: A 3-year-old girl was referred with complex craniosynostosis that had not been corrected surgically. She was asymptomatic despite the cranial MRI showed a Chiari malformation and one year later she developed a cervico-dorso-lumbar syringomyelia. She underwent a decompressive suboccipital craniectomy but subsequently suffered a worsening of syringomyelia...

Reconstruction of complex skull defects requires collaboration between neurosurgeons and plastic surgeons to choose the most appropriate procedure, especially in growing children. The authors describe herein the reconstruction of an extensive traumatic bone and soft tissue defect of the cranial vault in an 11-year-old boy. The size of the defect, quality of the tissues, and patient's initial condition required a 2-stage approach. Ten months after an initial emergency procedure in which lacerated bone and soft tissue were excised, reconstruction was performed...
