Adding Value to the Magnetic Resonance Examination in a Case of Brachial Plexus Birth Palsy.

We report a case of brachial plexus birth palsy in an infant with the inability to move the left upper limb since birth. There was neither history of birth trauma nor any complications during delivery. Magnetic resonance imaging (MRI) of brachial plexus showed postganglionic injury with musculoskeletal abnormalities.

Neuroblastoma involvement of the falx cerebri.

Involvement of the falx cerebri in infants with stage 4 neuroblastoma is thought to be rare. The falx is derived from the neural crest and thus may be a location for primary neuroblastoma. Its propensity for metastasis is unknown.

Imaging of congenital mesoblastic nephroma with pathological correlation.

Background: There are a variety of imaging findings for congenital mesoblastic nephroma (CMN) and two main pathological variants: classic and cellular.

Objective: To determine whether imaging findings in children can predict the likely pathological variant.

Materials And Methods: We reviewed imaging in children with pathology-proven CMN.

The fetal cerebellar vermis: assessment for abnormal development by ultrasonography and magnetic resonance imaging.

Fetal magnetic resonance provides a new tool in the imaging of the posterior fossa and is proving useful in cases that are difficult to assess sonographically by allowing further assessment of the fourth ventricle, cisterna magna, and vermian growth and development. We describe various criteria with which to evaluate vermian growth, including vermian biometry and the relationship between the superior and inferior lobes. We demonstrate 2 markers of normal vermian development: the primary fissure and fastigial point.

CT of the chest in the evaluation of idiopathic pulmonary arterial hypertension in children.

Background: Idiopathic pulmonary arterial hypertension (IPAH) is a rare disease in children. By definition it is a diagnosis of exclusion, and CT of the chest is primarily performed to exclude other causes. Previous studies have defined CT features suggestive of the diagnosis of IPAH, but these have all been limited to the adult population.

First trimester ultrasound diagnosis of lethal multiple pterygium syndrome.

Objective: Diagnosis of lethal multiple pterygium syndrome in the first trimester of pregnancy.

Methods: A 38-year-old woman attended our ultrasound (US) clinic at 11.2 weeks gestation.
