The liver has a complex vascular supply, which involves the inflow of oxygenated blood through the hepatic artery (systemic circulation) and deoxygenated blood through the portal vein (portal circulation), as well as the outflow of deoxygenated blood through the hepatic veins to the inferior vena cava. A spectrum of vascular variants can involve the liver. Some of these variants may result in areas of enhancement that can mimic more serious pathologic conditions. In this article, the authors discuss a spectrum of variants and pathologic conditions that may involve the liver vasculature...

BACKGROUND CONTEXT: A paucity of data exists studying outcomes of patients with syringomyelia undergoing spinal deformity correction. The literature does not stratify patients by syrinx size, which is likely a major contributor to outcomes. PURPOSE: To compare differences in outcomes between patients with large (≥ 4mm) and small syrinxes (< 4mm) undergoing spinal deformity correction. DESIGN: Retrospective review PATIENT SAMPLE: 28 patients (11 with large syrinx [LS, ≥ 4mm] and 17 with small syrinx [SS, < 4mm])...

OBJECTIVE A fibrous structure located dorsal to the dura at the posterior craniocervical junction stretches horizontally between the bilateral occipital condyles and the upper borders of the C-1 laminae. Partially covered by the occipital bone, this structure is always encountered when the bone is removed from the foramen magnum rim during approaches to the posterior cranial fossa. Although known to surgeons, this structure has not been defined, studied, or named. The most appropriate name for this structure is "the suboccipital ligament," and a detailed rationale for this name is provided...

BACKGROUND AND PURPOSE: A thick corpus callosum (TCC) can be associated with a very grave outcome in fetuses, but its clinical presentation in older children seems to be markedly different. METHODS: The corpus callosum (CC) was defined as thick based on observations and impressions. We reviewed cases of children who were diagnosed as TCC based on brain magnetic resonance imaging (MRI) studies. The pertinent clinical data of these children were collected, and their CCs were measured...

PURPOSE: The standardized sonographic hip screening according to Graf has increased reliability and comparability of measurements in the screening of developmental dysplasia of the hip (DDH). However, examiner dependent factors have been discussed to influence sonographic measurements. The objectives of this study were to examine the tolerance of the transducer positioning and to analyse the impact of transducer inclinations on Graf's hip grading system. MATERIALS AND METHODS: Twenty-four hips in consecutive newborns were screened sonographically in combination with an optoelectronic motion capture system to trace transducer positions in space...

Syringomyelia (SM) develops due to the disturbance of cerebrospinal fluid dynamics, spinal fixation or a spinal tumor. The disturbance of cerebrospinal fluid dynamics in the area of the foramen magnum leads to the progression of SM in Chiari 1 malformation (CM1). CM1 is the most prevalent pathology of craniovertebral junction associated with SM. The prevalence of CM1 varies from 3 to 8 per 100 000 population but SM is diagnosed in 65% of patients with CM1. Clinical symptoms of CM1 and SM include pain in the occipital area, gait disturbances due to sensitive ataxia, dissociated sensory disorders, dysphagia, paresis of the extremities...

Thin, slender, filament like structure is common finding in right atrium echocardiographically. These structures generally represent embryological remnants like thebasian valve, eustachian valve and chiari network. Apart from these variants, they can also be initial finding of thrombotic process specially in the presence of central venous catheter. Early detection and removing the catheter can prevent further thromboembolism in such cases.

Inferior vena cava (IVC) filters are useful adjuncts to prevent venous thromboembolism to the pulmonary circulation in the setting of contraindication for anticoagulation. Despite their proven decreased rate of pulmonary embolism, IVC filters are not without complications. We herein present the case of a 22-year-old man with a history of antiphospholipid antibody syndrome who was sent to our institution for evaluation with Budd-Chiari and post-thrombotic syndromes associated to a chronic retrohepatic complete IVC occlusion secondary to an IVC filter placed 5 years earlier...

Importance: Referral to a neurologist and imaging play important roles in the management of laryngeal cleft. Swallowing involves a complex series of neuromuscular interactions, and aspiration can result from anatomical causes (eg, laryngeal cleft), neuromuscular disorders, or some combination thereof. To date, no protocols or guidelines exist to identify which patients with laryngeal cleft should undergo neuroimaging studies and/or consultation with a neurologist. Objective: To establish guidelines for neurologic evaluation and imaging techniques to identify or rule out neuromuscular dysfunction in children with laryngeal cleft...

INTRODUCTION: Type I is the most common Chiari malformation in children. In this condition, the lower part of the cerebellum, but not the brain stem, extends into the foramen magnum at the base of the skull leading to intermittent brain hypertension. In symptomatic children, central sleep apneas are shown in polysomnography evaluation. A central apnea index of 1/h or more is considered abnormal, but >5/h is clearly considered pathological. Therefore, central sleep apnea evaluation in pediatric age may show great age-related variability...

A Cavalier King Charles Spaniel dog was presented because of a 10-d history of progressive vomiting, inappetence, and lethargy, with mild neurologic signs. Fine-needle aspirates of splenic nodules seen on ultrasound were suggestive of a carcinoma. On autopsy, a disseminated neoplasm was present in the lung, spleen, and adrenal glands. Additionally, there was a Chiari-like malformation of the skull with corresponding syringomyelia of the cranial spinal cord. Histologically, the neoplasm was comprised of a pleomorphic population of round cells with a high mitotic rate...

Insulin allergy has been uncommon since the introduction of human recombinant insulin preparations; the prevalence is 2.4%. Insulin injection could elicit immediate reactions, which are usually induced by an IgE-mediated mechanism, within the first hour after drug administration. In the present study, we describe the case of a child who experienced immediate urticaria after long-acting insulin injection. A 9-year-old girl affected by type I diabetes mellitus referred a history of three episodes of urticaria 30 min after insulin subcutaneous injection...

To describe the prevalence and incidence density of hospital-acquired unavoidable pressure sores among patients aged ≥65 years admitted to acute medical units. A secondary analysis of longitudinal study data collected in 2012 and 2013 from 12 acute medical units located in 12 Italian hospitals was performed. Unavoidable pressure ulcers were defined as those that occurred in haemodynamically unstable patients, suffering from cachexia and/or terminally ill and were acquired after hospital admission. Data at patient and at pressure ulcer levels were collected on a daily basis at the bedside by trained researchers...

Spontaneous intracranial hypotension (SIH) is classified as a decrease in cerebrospinal fluid (CSF) pressure secondary to a CSF leakage and consequent descent of the brain into the foramen magnum. Diagnosing SIH can be difficult due to its overlapping findings with Arnold-Chiari type 1 Malformation (CM1) where the cerebellar tonsils herniate into the foramen magnum. The similarity of both conditions calls for a more reliable imaging technique to localize the CSF leak which could narrow the differential diagnosis and aid in choosing the correct treatment...
