Case ReportsThoracic malignant peripheral nerve sheath tumour mimicking a pleural tumour: a rare pedunculated appearance.
A malignant peripheral nerve sheath tumour (MPNST) generally occurs in adults and often in patients with neurofibromatosis-1 (NF-1). We present a rare case of a huge thoracic MPNST arising from the intercostal nerve in a 12-year-old girl without NF-1. In addition to the unusual occurrence in a child without NF-1, MRI demonstrated a unique pedunculated appearance mimicking a pleural tumour. In this report, we present the CT and MRI findings of our case, together with the histopathological findings, and review previous reports.

ReviewPaternal uniparental disomy 14: introducing the "coat-hanger" sign.
Paternal uniparental disomy for chromosome 14 (patUPD14) is a rare condition, this being the eighth report. A male infant, born prematurely, was noted to have extremely lax skin and bilateral inguinal hernias. Skin biopsy confirmed the clinical diagnosis of congenital cutis laxa, but this did not explain the limb abnormalities. ⋯ The patient died after prolonged respiratory failure. This combination of patUPD14 and congenital cutis laxa has not previously been described. Radiology can play a pivotal role in guiding the geneticist's choice of investigation.

ReviewSclerotherapy in aneurysmal bone cysts in children: a review of 17 cases.
To determine the efficacy of percutaneous sclerotherapy in the treatment of aneurysmal bone cysts. ⋯ Percutaneous sclerotherapy of aneurysmal bone cysts with Ethibloc is safe and effective. It is an important alternative to surgery, especially when surgery is technically impossible or not recommended in high-risk patients.

Comparative StudyThe effect of screening sonography on the positive rate of enemas for intussusception.
The referring physicians at our institution used the enema as a diagnostic test in children with suspected intussusception. ⋯ Screening US has decreased unnecessary enemas for clinically suspected intussusception, increasing positive findings from 22% to 58%. This has in turn reduced children's exposure to radiation.

Trilateral retinoblastoma is the association of bilateral retinoblastomas and an intracranial primitive neuroectodermal tumour. Bilateral retinoblastomas with a pineal tumour are typical manifestations of this association. ⋯ The intracranial tumour can occur in the suprasellar or parasellar regions even before presentation of the retinal mass. We report a female infant with a suprasellar retinoblastoma and unilateral intraocular retinoblastoma.
