Characteristics associated with spine injury on magnetic resonance imaging in children evaluated for abusive head trauma.

Background: Spine injuries are increasingly common in the evaluation for abusive head trauma (AHT), but additional information is needed to explore the utility of spine MRI in AHT evaluations and to ensure an accurate understanding of injury mechanism.

Objective: To assess the incidence of spine injury on MRI in children evaluated for AHT, and to correlate spine MRI findings with clinical characteristics.

Materials And Methods: We identified children younger than 5 years who were evaluated for AHT with spine MRI.

Infant with nasolacrimal sinonasal myxoma: Diffusion MRI features.

We report the imaging features of a rare sinonasal myxoma situated over the right nasolacrimal duct in a 5-month-old male. We emphasize the importance of including sinonasal myxomas in the list of differential diagnostic possibilities when encountering a nasolacrimal gland mass in an infant, and describe the CT and MRI characteristics of this rare entity.

Myelin, myelination, and corresponding magnetic resonance imaging changes.

Accurate diagnosis of white matter diseases requires a thorough understanding of white matter maturation. These maturational changes are complex and require knowledge of the histologic background and time course of development. This article reviews the in vivo magnetic resonance (MR) appearance of myelination with emphasis on the appearance of different regions of the brain using various pulse sequences at different developmental time points.

Spinal cord involvement in a child with raccoon roundworm (Baylisascaris procyonis) meningoencephalitis.

A 14-month-old previously healthy boy developed progressively worsening neurological symptoms secondary to eosinophilic meningoencephalitis with myelitis caused by raccoon roundworm (Baylisascaris procyonis) infection. MRI demonstrated T2 hyperintensity and enhancement of the cerebral white matter, cerebellum and spinal cord. Prior case reports have described signal abnormality within the brains of patients with raccoon roundworm neural larva migrans (NLM).

An unusual case of hydranencephaly presenting with an anterior midline cyst, a posterior calcified mass, cerebellar hypoplasia and occlusion of the posterior cerebral arteries.

We present an unusual case of severe hydranencephaly in a term infant who presented with the following additional unique features, which were discovered on CT, MRI and MR angiography examinations: (1) occlusion of the bilateral posterior cerebral arteries, (2) absence of the occipital lobes, (3) an ovoid calcified mass sitting on the inner table of the occipital bone, (4) severe cerebellar hypoplasia, (5) a dysmorphic cystic diencephalon, (6) a large anterior midline cyst just above the cribriform plate and (7) absence of the falx. These imaging findings were confirmed at autopsy.
