OBJECTIVE: This article describes, illustrates, and correlates imaging and pathologic features of primary vascular mesenchymal neoplasms of the liver, which arise from the vascular endothelium and perivascular epithelioid cells. CONCLUSION: Familiarity with the spectrum of benign, malignant-potential and malignant vascular neoplasms, and nonneoplastic mimickers allows consideration in the differential diagnosis of enhancing hepatic masses. Understanding relevant pathologic features facilitates recognition of key imaging features, specifically dynamic contrast enhancement patterns on CT and MRI, which provide a useful classification system...

BackgroundThe majority of pituitary adenomas are sporadic, but about 5% of them occur in a familial setting, predominantly in multiple endocrine neoplasia type 1 and Carney complex. Familial isolated pituitary adenomas (FIPA), unrelated to the syndromes mentioned above, were also described. The clinical course of FIPA differs significantly from sporadic cases, and is characterized by a larger tumor size, more aggressive course and younger patients' age at the moment of recognition. ObjectivesThe aim of this retrospective study is to present 4 families in which two closely related people were diagnosed with pituitary adenomas...

Tuberculosis (TB) remains a major public health problem across the globe. A common form of extrapulmonary TB (EPTB) with high mortality and morbidity is neuro TB or tuberculosis of the nervous system. The management of brain TB remains a big challenge due to the lack of specific diagnostic tools and appropriate treatment guidelines. In this context, this manuscript discusses clinical, diagnostic and treatment dilemmas in the management of intracranial tuberculomas. Brain tuberculoma may occur at any site within the cranium, no part of the brain substance or ventricular surface being exempt...

Posttreatment imaging of primary bone tumours represents a diagnostic challenge for radiologists. Depending on the primary bone tumour common radiological procedures, such as radiography, computed tomography (CT), and magnetic resonance imaging (MRI), are employed. Radiography and CT are particularly useful in benign bone tumours and in matrix-forming bone tumours. MRI comes into consideration with malignant tumour recurrence and tumoral soft tissue infiltration. Bone scintigraphy is of superior importance if a primarily multifocal manifestation of bone tumour or metastasizing tumour disease is suspected...

BACKGROUND: Odontoid process pathologies can cause upper motor neuron lesions. These pathologies can be approached through either a high retropharyngeal approach or a transoral approach. The introduction of the surgical microscope, proper instrumentations, and proper antibiotics has increased utilization of the transoral approach. QUESTIONS/PURPOSES: Our approach to anterior odontoid resection through transoral approach for different pathologies resulting in compression the cervical cord or causing craniocervical instability is described here...

Isolated sulfite oxidase deficiency (ISOD) is a life-threatening, autosomal recessive disease characterized by severe neurological impairment. As no long-term effective treatment is available, distinction from other treatable diseases, such as molybdenum cofactor deficiency (MoCD) type A, should be made. We reviewed 47 patients (45 previously reported in the literature). Cases were reviewed for consanguinity, sex, age at onset, death, clinical findings (including spasticity, seizures, psychomotor retardation, feeding difficulties, ectopia lentis, microcephaly), laboratory findings [urinary sulfite, S-sulfocysteine (in plasma and urine), plasma cystine, total homocysteine, uric acid, and oxypurines in urine] and radiological findings (including cerebral/cerebellar atrophy, cystic white matter changes, ventriculomegaly)...

We report the CT and MRI findings in two cases of hemorrhagic infarct of the basal ganglia (BG), following out-of-hospital cardiac arrest (CA). In case 1, Brain-CT realized at day 2 showed bilateral and almost symmetric hemorrhagic infarct of the BG and infarct of the tectum of the mesencephalon. In case 2, MRI realized at day 6 showed hemorrhagic infarct of both lenticular nuclei on T2 GE images. In both cases there was no medical history and the cardiovascular and the coagulation profile were normal. In these cases, the lesions are observed earlier than reported in a few previous radiological cases...

ISSUE: Ultrasound is an integral part of imaging diagnostics but, unlike CT or MRI, requires the physician to have advanced technical skills for the implementation and documentation of studies. CURRENT SITUATION: Owing to poor remuneration and the large effort required, ultrasound is not a priority at many institutions, and compared to CT, MRI or interventions, little reward is given to those committed to ultrasound. Intense practical teaching is rarely given. As a result, residents have to teach themselves or gain experience during rotations outside radiology...

BACKGROUND CONTEXT: Dural laceration frequently occurs during surgery in patients with OLF, mainly due to dural adhesion (DA) and dural ossification (DO) between the ligamentum flavum and dura mater. However, the radiologic predictive factors of DA in OLF have rarely been reported. PURPOSE: To determine the preoperative radiologic signs for predicting intraoperative DA in ossification of the ligamentum flavum (OLF), by using preoperative magnetic resonance imaging (MRI) and computed tomography (CT)...

REVIEW
Jesse Hatgis, Michelle Granville, Robert E Jacobson
Baastrup's disease or "kissing spines syndrome" was first described as a cause of lumbar pain before computerized tomography (CT) and magnetic resonance imaging (MRI) scanning existed. The diagnosis was based on x-ray studies, which showed that the spinous processes, especially in the lower lumbar spine, became approximated to each other and this was a generator of positional back pain. Biomechanically, the interspinous and supraspinous ligaments that are degenerated in Baastrup's disease normally contribute significantly to sagittal alignment...

PURPOSE: Because of awareness of iatrogenic radiation exposure, there is a national trend of diminishing computed tomography (CT) use for pediatric suspected appendicitis. The purpose of this study was to evaluate the effects of a CT reduction program for evaluation of appendicitis. METHODS: A multidisciplinary group (emergency medicine, radiology, and surgery) at a children's hospital developed a reduction program which included: ultrasound (U/S) first (2012), magnetic resonance imaging (MRI) second (2014), and standardized U/S reports (2016)...

BACKGROUND: Brain dermoid cysts are very rare lesions. Although benign, these cysts may be associated with devastating complications due to mass effect or meningitis. The discovery of completely asymptomatic dermoid cysts in the pediatric population is exceedingly rare. Despite the advances in imaging modalities, it sometimes remains difficult to exclude the differential diagnosis of craniopharyngioma. CASE REPORT: We describe a 12-year-old boy addressed for suspicion of craniopharyngioma diagnosed by decreased visual acuity, bitemporal hemianopia and a CT scan showing a large hypodense suprasellar lesion with intralesional calcifications...

Diagnostic radiology reports are increasingly being made available to patients and their family members. However, these reports are not typically comprehensible to lay recipients, impeding effective communication about report findings. In this paper, we present three studies informing the design of a prototype to foster patient-clinician communication about radiology report content. First, analysis of questions posted in online health forums helped us identify patients' information needs. Findings from an elicitation study with seven radiologists provided necessary domain knowledge to guide prototype design...
