INTRODUCTION: Osteosarcoma is a malignant mesenchymal tumor including cells that present an osteoblastic differentiation. On the skull, it has often extra-axial development associated with bone reaction. We report an atypical and rare case of intracranial or cerebral osteosarcoma underline the radiological and pathological diagnostic difficulties. CASE REPORT: Our case concerns a primary osteosarcoma without bone involvement in a 10-year old boy who was admitted for intracranial hypertension with progressive worsening and brachial monoparesis...

We describe the youngest case to date of a 2 year old child who developed central skull base osteomyelitis (SBO) initially presenting with a fever, vomiting and sore throat. An extremely rare complication of mastoiditis following otitis media in children is SBO which can present with non-specific symptoms. This report describes the first case of symptomatic ischaemic stroke secondary to SBO in an immunocompetent child. We review the literature of the management and the potential cerebrovascular complications of central SBO in children secondary to otolaryngological infection...

Chiari malformation type I (CM-I) and hydrocephalus are often associated with complex craniosynostosis. On the contrary, their simultaneous occurrence in monosutural synostosis is extremely rare. The pathophysiological hypothesis is that they may alter posterior fossa growth and lead to cerebellar tonsil herniation also without skull base primary involvement. Hydrocephalus is multifactorial and may be secondary to fourth ventricle outlet obstruction. The management of these cases is quite complex and not well defined...

OBJECTIVE: The prevalence of skull fractures after mild head trauma is 2 % in children of all ages and 11 % in children younger than 2 years. The current standard management for a child diagnosed with an isolated skull fracture (ISF), in our institute, is hospitalization for a 24-h observation period. Based on data from the literature, less than 1 % of all minor head injuries require neurosurgical intervention. The main objective of this study was to evaluate the risk of neurological deterioration of ISF cases, in order to assess the need for hospitalization...

BACKGROUND AND OBJECTIVE: Studies on traumatic injuries of children indicate that impact to the head is a major cause of severe injury and high mortality. However, regulatory and ethical concerns very much limit development and validation of computer models representing the pediatric head. The purpose of this study was to develop a child head finite element model with high-biofidelity to be used for studying pediatric head injury mechanisms. METHODS: A newly developed 10-year-old (YO) pediatric finite element head model was limitedly validated for kinematic and kinetic responses against data from quasi-static compressions and drop tests obtained from an experimental study involving a child-cadaver specimen...

Eosinophilic granuloma (EG) represents a local form of Langerhans cell histiocytosis that occurs mostly in children. It usually presents with a gradually enlarging painless skull mass, and rarely presents a rapid clinical deterioration. This 7-year-old boy who was diagnosed with EG, based on a magnetic resonance imaging scan, after presenting with a painless right parietal swelling of 7-week duration. Three weeks prior his scheduled surgery, he presented to the emergency department with a 2-day history of sudden increased of the subcutaneous swelling associated with a headache, vomiting, and decreased the level of consciousness; there was no history of trauma...

Adrenocorticotropin-independent adrenal hyperplasias are rare diseases, which are classified into macronodular (>1 cm) and micronodular (≤1 cm) hyperplasia. Micronodular adrenal hyperplasia is subdivided into primary pigmented adrenocortical disease and a limited or nonpigmented form 'micronodular adrenocortical disease (MAD)', although considerable morphological and genetic overlap is observed between the 2 groups. We present an unusual case of a 44-month-old girl who was diagnosed with Cushing syndrome due to MAD...

Langerhans cell histiocytosis (LCH), formerly known as histiocytosis X, refers to a spectrum of diseases characterized by idiopathic proliferation of histiocytes that produce either focal (localized LCH) or systemic manifestations (Hand-Schüller-Christian disease and Letterer-Siwe disease). Localized LCH accounts for approximately 60-70 % of all LCH cases. Osseous involvement is the most common manifestation and typically involves the flat bones, along with lesions of the skull, pelvis, and ribs. Localized LCH in bone shows a wide spectrum of clinical manifestations and radiologic features that may mimic those of infections as well as benign and malignant tumors...

To account for the effects of head realistic morphological feature variation on the impact dynamic responses to head injury, it is necessary to develop multiple subject-specific pediatric head finite element (FE) models based on computed tomography (CT) or magnetic resonance imaging (MRI) scans. However, traditional manual model development is very time-consuming. In this study, a new automatic method was developed to extract anatomical points from pediatric head CT scans to represent pediatric head morphological features (head size/shape, skull thickness, and suture/fontanel width)...

This publication was designed to describe a rare case of development of apicalpetrositis in a child presenting with acute otitis mediafollowing chicken pox experienced in the preceding period. We carried out the study with the use of computed tomography (CT) that demonstrated destruction of the temporal bone, bones of the base of the skull and of the first cervical vertebra. The treatment strategy chosen for the management of this condition that included antibiotic therapy and expectant observation proved justified and can be recommended as an algorithm of choice taking into consideration the difficulty of surgical approach to the apex of the petrous pyramid...

An encephalocele is a protrusion of the brain and/or meninges through a defect in the skull. Based on the location of the skull defect they are classified into sincipital, basal, occipital or parietal varieties. Occurrence of more than one Encephalocele in a patient is very rare and very few cases of double encephalocele are reported. We report an interesting case where a parietal and an occipital encephalocele were present together. The patient was a 2 months boy who was brought to us with complaints of two swelling on the scalp since birth...

INTRODUCTION: Rhabdomyosarcoma (RMS) is the most frequent soft-tissue sarcoma in children and makes up 5% of all pediatric malignant tumors. The main head and neck locations are the base of the skull, nasopharynx, nasal cavity and orbit. An outer ear location is considered extremely rare. We present 3 cases of children, aged 6 to 14 years, presenting with auricular RMS. CASE REPORTS: The first child, aged 6, was managed by 4 chemotherapy cycles followed by surgical resection of the tumor bed, completed by 5 further cycles of chemotherapy...

BACKGROUND: Patients with syndromic forms of craniosynostosis may experience functional problems such as raised intracranial pressure, proptosis, obstructive sleep apnoea and failure to thrive. The monobloc fronto-facial advancement with osteogenic distraction is increasingly used to correct these functional problems in one procedure as well as improve appearance. The authors report the phenomenon of post operative aberrant facial flushing - an unusual and previously unreported complication of the procedure...

We report an unusual combination of features comprising delayed tooth eruption and closure of the anterior fontanel as the sole presenting features in a child with cleidocranial dysplasia (CCD). Radiological survey revealed the presence of wormian bones in the skull, pseudoepiphysis at the base of the bilateral second metacarpal, and midline ossification defects at pubic symphysis in the presence of essentially normal clavicles. DNA sequencing of the RUNX2 gene detected a novel nonsense mutation in exon1 (c...

BACKGROUND: Rhinoliquorrhoea suggests a communication between the subarachnoid space and the sinonasal tract. Clinical presentation includes clear nasal discharge, headache, pneumocephalus, meningitis or brain abscess. Cerebrospinal fluid (CSF) leaks are mostly of traumatic origin (skull base fractures), iatrogenic (secondary to endoscopic endonasal surgery) or associated with tumour aetiology. Occasionally, hydrocephalus has been the cause of rhinoliquorrhoea in adults, presumably secondary to the chronically raised intracranial pressure with skull base erosion and meningocele...

Vascular access in the neonate can be challenging, especially in preterm infants. When other access is not available, superficial scalp veins can be safely used for vascular access. However, rare and potentially catastrophic complications can occur due to unique features of the neonatal skull and soft-tissue anatomy. The authors report a rare complication of vascular access in a preterm infant, which led to the direct infusion of parenteral nutrition into the intracranial space. The child had an excellent outcome after open drainage and irrigation of bilateral intracranial spaces and the spinal thecal sac...

BACKGROUND: Pediatric traumatic brain injury (TBI) constitutes a significant burden and diagnostic challenge in the emergency department (ED). While large North American research networks have derived clinical prediction rules for the head injured child, these may not be generalizable to practices in countries with traditionally low rates of computed tomography (CT). We aim to study predictors for moderate to severe TBI in our ED population aged < 16 years. METHODS: This was a retrospective case-control study based on data from a prospective surveillance head injury database...
