Non-traumatic wrist pain remains a diagnostic challenge. An accurate diagnosis is crucial in order to choose the appropriate treatment. We report the case of a 23-year-old female with a four-month history of mainly nocturnal wrist pain. There was no history of trauma or prior surgery. Radiographs and CT scans showed a lytic lesion with central nidus and sclerotic margins in the pisiform bone. Bone scan showed increased uptake in the pisiform bone. The diagnosis of osteoid osteoma was confirmed by histopathological analysis after complete surgical resection...

Brain magnetic resonance (MR) represents a useful and feasible tool for the differential diagnosis of Parkinson's disease. Conventional MR may reveal secondary forms of parkinsonism and may show peculiar brain alterations of atypical parkinsonian syndromes. Furthermore, advanced MR techniques, such as morphometric-volumetric analyses, diffusion-weighted imaging, diffusion tensor imaging, tractography, proton MR spectroscopy, and iron-content sensitive imaging, have been used to obtain quantitative parameters useful to increase the diagnostic accuracy...

Traumatic hip dislocations in children are not frequent but constitute true emergencies. They require urgent reduction because of the risk of consecutive avascular necrosis of the femoral head. We report a 6-year-old boy with traumatic posterior hip dislocation on a vacation abroad. After closed reduction the day of the accident, a hip spica cast was applied and the patient was transferred home. Once home, X‑ray and CT diagnostics were completed by MRI. In future, long-term clinical and radiological investigations for avascular necrosis and growth disorders, as well as thoroughly informing the parents, should be mandatory...

PURPOSE: Traumatic diaphragm rupture (TDR) is a rare complication of trauma in pediatric age and may be easily missed by the severity of associated injuries so that delayed emergent presentation can occur with increased rate of morbidity and mortality. No review has been available to guide clinicians through the pitfalls and the initial diagnostic approach to pediatric TDR. METHODS: A Medline thorough search on TDR was conducted using different queries. English language citations were identified during the period of January 2000 through December 2014 limiting the search to pediatric age (0-18 years)...

INTRODUCTION: Differences in systolic blood pressure reading between arms are common but could signal trouble if the discrepancy is significant. Early detection of aortic dissection could invariably determine patient's survivability. Hence, a high index of suspicion with prompt diagnostic imaging is vital for accurate diagnosis. CASE PRESENTATION: A previously healthy 35-year-old lady was referred from district hospital for hypertensive cardiomyopathy complicated by acute pulmonary oedema...

INTRODUCTION: The antenatal diagnosis of open spina bifida (OSB), a neural tube defect, is predominantly made at the second trimester morphology scan by ultrasound detection of structural abnormalities resulting from the associated Chiari II malformation. Evidence has emerged suggesting that these structural abnormalities can be detected earlier, by examination of the posterior fossa as part of the first trimester nuchal translucency scan. In particular, absence of the intra-cranial translucency (IT) of the fourth ventricle has shown promise as a diagnostic marker of OSB, although the sensitivity and specificity of this finding varies widely in the literature...

Cystic renal masses are a specific renal entity with a different management from solid lesions. Renal cysts are present in over 50% of patients after 50 years. Radiological diagnostic enables to rank their suspect nature of malignancy through the Bosniak classification. Type III and IV lesions are at high risk of malignancy, and are usually treated by partial nephrectomy.

The American College of Radiology develops evidence-based practice guidelines to aid appropriate utilization of radiological procedures. Panel members use expert opinion to weight trade-offs and consensus methods to rate appropriateness of imaging tests. These ratings include an equivocal range, assigned when there is disagreement about a technology's appropriateness and the evidence base is weak or for special circumstances. It is not clear how expert consensus merges with the evidence base to arrive at an equivocal rating...
