OBJECTIVE: Cranial vault remodeling surgery for craniosynostosis carries the potential risk of dural venous sinus injury given the extensive bony exposure. Identification of the dural venous sinuses can be challenging in patients with craniosynostosis given the lack of accurate surface-localizing landmarks. Computer-aided design and manufacturing (CAD/CAM) has allowed surgeons to pre-operatively plan these complex procedures in an effort to increase reconstructive efficiency. An added benefit of this technology is the ability to intraoperatively map the dural venous sinuses based on pre-operative imaging...

BACKGROUND: Brain dermoid cysts are very rare lesions. Although benign, these cysts may be associated with devastating complications due to mass effect or meningitis. The discovery of completely asymptomatic dermoid cysts in the pediatric population is exceedingly rare. Despite the advances in imaging modalities, it sometimes remains difficult to exclude the differential diagnosis of craniopharyngioma. CASE REPORT: We describe a 12-year-old boy addressed for suspicion of craniopharyngioma diagnosed by decreased visual acuity, bitemporal hemianopia and a CT scan showing a large hypodense suprasellar lesion with intralesional calcifications...

Diagnostic radiology reports are increasingly being made available to patients and their family members. However, these reports are not typically comprehensible to lay recipients, impeding effective communication about report findings. In this paper, we present three studies informing the design of a prototype to foster patient-clinician communication about radiology report content. First, analysis of questions posted in online health forums helped us identify patients' information needs. Findings from an elicitation study with seven radiologists provided necessary domain knowledge to guide prototype design...

The effects of trauma in children are different due to association with some anatomical and physiological differences compared with adults. The role of neuroimaging gains importance in early detection of traumatic brain injuries and prevention of secondary post-traumatic complications. Many algorithms are described for children with head trauma to decide the necessity of a computed tomography scan. The aims of this article are to describe differences of these algorithms, the mechanism of traumatic brain injury with radiological imaging findings in the pediatric population, and explain complications of undiagnosed traumatic brain lesions...

BACKGROUND: Ballistic injuries with retained foreign bodies from air guns is a relatively common problem, particularly in children and adolescents. If not removed in a timely fashion, the foreign bodies can result in complications, including pain and infection. Diagnostic methods to identify the presence of the foreign body run the entire gamut of radiology, particularly radiography, ultrasound (US) and computed tomography (CT). Removal of the foreign bodies can be performed by primary care, emergency, surgical, and radiologic clinicians, with or without imaging guidance...

INTRODUCTION: Diffusion-weighted magnetic resonance imaging (DW-MRI) allows noninvasive investigation of brain structure in vivo. Diffusion tensor imaging (DTI) is a frequently used application of DW-MRI that assumes a single main diffusion direction per voxel, and is therefore not well suited for reconstructing crossing fiber tracts. Among the solutions developed to overcome this problem, constrained spherical deconvolution with probabilistic tractography (CSD-PT) has provided superior quality results in clinical settings on adult subjects; however, it requires particular acquisition parameters and long sequences, which may limit clinical usage in the pediatric age group...

The Central nervous system can be affected in extrapulmonary tuberculosis. The intracranial tuberculoma occurrence is a rare entity occurrence; most often occur in the form of discrete small multiple lesions. Rarely a large sized tuberculoma is observed with mass effects and usually managed surgically to provide rapid relief of mass effect, histopathological confirmation of diagnosis, reduction of pathological mass thereby increasing efficacy of medical therapy. Author reports an extremely rare case of giant tuberculoma occurring in a pediatric patient, which was managed with antituberculous medication along with cerebral decongestant...

Chordomas are primary malignant bone tumors that arise in the axial skeleton, believed to originate from remnants of embryologic notochordal cell rests. Multicentric origin of chordoma is extremely rare. To our literature search, we found only three cases of multicentric chordoma in adults. We report a first case of multicentric chordoma in pediatric age group. A 14-month-old child presented with torticolis and left upper limb monoparesis, imaging showed expansile bony destructive lesion in clivus and dorsal spine simultaneously...
