Residual or recurrent cerebellar low-grade glioma in children after tumor resection: is re-treatment needed? A single center experience from 1983 to 2003.

Purpose: The aim of this study was to report on children with cerebellar low-grade glioma (LGG), who were found to have progressive or nonprogresssive residual tumors or tumor recurrence after tumor resection.

Patients And Methods: Medical records and magnetic resonance imaging (MRI) studies of children (<16 years) with cerebellar LGG were retrospectively analyzed.

Results: Of 289 patients with CNS tumors referred between 1983 and 2003, 28 (9.

Accuracy of preoperative routine MRI for hepatic lesion detection.

Background: The outcome of liver resections depends on complete removal of all detectable foci. Our aim was to determine the value of preoperative routine magnetic resonance imaging (MRI) for complete detection of hepatic lesions.

Methods: We compared 271 lesions seen on MRI in 182 patients to intraoperative findings (including intraoperative ultrasonography) and histology.

Predicting neurologic recovery in cervical spinal cord injury with postoperative MR imaging.

Study Design: Prospective, nonrandomized, observational cohort study.

Objectives: To determine whether the presence of spinal cord hemorrhage and length of hematoma on magnetic resonance imaging (MRI) is predictive of recovery in cervical spinal cord injury (SCI).

Summary Of Background Data: A clear picture of the location, extent, and severity of traumatic cervical cord injury can be obtained with MRI.

Aseptic osteonecrosis in children and adolescents treated for hemato-oncologic diseases: a 13-year longitudinal observational study.

Aseptic osteonecrosis (AON) is a serious long-term complication of childhood cancer therapy. A retrospective study was undertaken to describe treatment and long-term follow-up of patients with AON. Between 1990 and 2003, 630 consecutive children with various malignancies were treated at the University Children's Hospital in Graz, Austria.

Multimodal treatment of children with unresectable or recurrent desmoid tumors: an 11-year longitudinal observational study.

The primary goal of treatment for desmoid tumors is complete surgical resection to achieve negative margins. In adults with unresectable or recurrent lesions, treatment options include noncytotoxic and cytotoxic drugs, but little is known about nonsurgical treatment in children. Between 1992 and 2003 six children (four girls, two boys) with a median age of 2.

Is intraoperative ultrasonography during partial hepatectomy still necessary in the age of magnetic resonance imaging?

Background/aims: The aim of our study was to determine if intraoperative ultrasonography is still necessary in the time of magnetic resonance imaging.

Methodology: Our prospective study comprised 122 patients (82% with malignant tumors) undergoing partial hepatectomy with preoperative magnetic resonance imaging, done at the same institution using a standardized liver protocol as well as intraoperative ultrasonography performed in a systematic fashion.

Results: Seventeen additional malignant lesions in 16/122 patients (13.

Painful soft-tissue reaction to injectable Norian SRS calcium phosphate cement after curettage of enchondromas.

A prospective single-cohort study was designed to include 20 patients with enchondromas but was stopped because of poor early results. Four patients with an enchondroma, three in the proximal humerus and one in the distal femur, were treated by curettage and filling of the defect with Norian SRS cement. Clinical and radiological follow-up including CT and MRI was carried out for 18 months.
