Case ReportsInterhemispheric lipoma connected to subcutaneous lipoma via lipomatous stalk.
Lipomas are rare intracranial lesions and are generally thought to be asymptomatic. The vast majority of intracranial lipomas are viewed as incidental findings on imaging studies and treated conservatively. ⋯ We report an infant with a subgaleal lipoma in the region of the anterior fontanelle connected to a large interhemispheric (pericallosal) lipoma via a tiny lipomatous stalk. Because of this association, infants who present with a subcutaneous lipoma of the scalp might be considered for MR imaging to evaluate for an intracranial component.

Comparative StudyWhole-body MRI of paediatric malignant tumours: comparison with conventional oncological imaging methods.
To evaluate the usefulness of whole-body (WB) MRI for detecting metastases from paediatric malignant tumours in comparison with conventional oncological imaging methods. ⋯ WB MRI can substitute for bone scintigraphy in detecting skeletal metastases of paediatric malignant tumours, and it is useful in evaluating initial tumour staging and early treatment responses. However, it still has only a complementary role in detecting extraskeletal metastases.

Comparative StudyM-mode sonography of diaphragmatic motion: description of technique and experience in 278 pediatric patients.
The use of M-mode sonography for evaluation of diaphragmatic motion has only been previously reported in small series of children, and its use is not widespread among pediatric radiologists. ⋯ M-mode sonography should be the modality of choice to assess diaphragmatic motion, as it can easily depict diaphragmatic dysfunction and allows comparison of changes in follow-up studies. Normal chest radiographs are poor predictors of normal diaphragmatic motion.

Elevated lactate as an early marker of brain injury in inflicted traumatic brain injury.
Traumatic brain injury is a major cause of disability and death in the pediatric population. The metabolic and neurochemical abnormalities that underlie traumatic brain injury remain poorly understood, but hypoxia-ischemic injury might play an important role. ⋯ Patients with inflicted traumatic brain injury and evidence of hypoxic-ischemic injury as indicated by elevated lactate on MRS tend to have worse early neurological status and early outcome scores. Lactate levels as sampled by MRS might predict early clinical outcome in inflicted traumatic brain injury.
