PURPOSE The purpose of our study was to prospectively evaluate 3D time-of-flight (TOF) MR angiography (MRA) in the follow-up of 27 intracranial aneurysms treated with Guglielmi detachable coils (GDCs). METHOD From February 1997 to June 1998, 26 patients with 27 aneurysms were included in this prospective study. Aneurysms were located in the anterior(More)
Learning disabilities represent the main childhood complication in neurofibromatosis type 1 (NF1). Patients frequently exhibit T2-weighted hyperintensities called unidentified bright objects (UBOs) on brain magnetic resonance imaging (MRI), with unclear relationship to such cognitive disabilities. This study aimed to determine whether thalamo-striatal UBOs(More)
The three main categories of limb emergencies are trauma, infection and the painful hip. Conventional radiography is used as the initial screening imaging modality that can sometimes be complemented with sonography. Computed tomography and MRI are rarely needed. Familiarity with conditions specific to the pediatric population is essential to the diagnosis(More)
Neurofibromatosis type 1 (NF1) is frequently associated with hyperintense lesions on T2-weighted images called “unidentified bright objects” (UBO). To better characterize the functional significance of UBO, we investigate the basal ganglia and thalamus using spectroscopic imaging in children with NF1 and compare the results to anomalies observed on(More)
We report 2 cases of thoracic neural crest tumors complicating the course in patients with Beckwith-Wiedemann syndrome (BWS). In the first patient, a thoracic neuroblastoma was fortuitously discovered at age 3 months on a chest film prior to a partial glossectomy. In the follow-up left nephroblastoma and a right kidney simple cyst appeared. In the second(More)
The purpose of our study is to trace in vivo and during the perinatal period, the brain maturation process with exhaustive measures of the T2 relaxation time values. We also compared regional myelination progress with variations of the relaxation time values and of brain signal. T2 relaxation times were measured in 7 healthy premature newborns at the(More)
Gallbladder papilloma is a rare entity in children; We report one such case in a 7-year-old boy. Diagnosis suspected on a systematic echographic examination of the abdomen was confirmed at surgery. This 7-year-old boy had a 6 month history of fight upper quadrant abdominal pain. His physical exam and liver function tests were normal. An ultrasound(More)
A vestibular aqueduct midpoint width greater than 1.50 mm is currently considered to be pathognomonic for a large vestibular aqueduct syndrome. To analyse the diameter of the vestibular aqueduct in children as a function of age and consequently to determine if a fixed measure could serve as a pertinent diagnostic criterion. This was a retrospective study of(More)
