Subdural contrast effusion during endovascular therapy: case report

AbstractAccumulation of contrast medium in the subdural space after diagnostic intraarterial contrast administration is a rare observation. The authors report the case of a subdural contrast effusion (SCE) presenting during endovascular treatment of an intracranial dural arteriovenous fistula (DAVF) mimicking an acute subdural hematoma. Differentiation between the two by computed tomography (CT) or intraprocedural Dyna CT and early neurological examination can be crucial for patient management. We believe that repeated large-volume contrast injections via large-bore intermediate catheters into the territory of an (even partly) occluded DAVF may induce leakage of contrast medium into the extravascular subdural space thereby causing a SCE.

Authors: Wei L, Osman S, Hatt M, El Naqa I Abstract Due to the recent developments of both hardware and software technologies, multimodality medical imaging techniques have been increasingly applied in clinical practice and research studies. Previously, the application of multimodality imaging in oncology has been mainly related to combining anatomical and functional imaging to improve diagnostic specificity and/or target definition, such as positron emission tomography/computed tomography (PET/CT) and single-photon emission computed tomography (SPECT)/CT. More recently, the fusion of various images, such as multi-...

Authors: Bogowicz M, Vuong D, Huellner MW, Pavic M, Andratschke N, Gabrys HS, Guckenberger M, Tanadini-Lang S Abstract Today, rapid technical and clinical developments result in an increasing number of treatment options for oncological diseases. Thus, decision support systems are needed to offer the right treatment to the right patient. Imaging biomarkers hold great promise in patient-individual treatment guidance. Routinely performed for diagnosis and staging, imaging datasets are excepted to hold more information than used in the clinical practice. Radiomics describes the extraction of a large number of meaningfu...

In conclusion, reducing miR-451a expression levels could enhance bone formation during the progression of osteoporosis, which might be at least partly via the meditation of Bmp6 expression.

CONCLUSIONS: Pelvic fracture MRI should be performed primarily in elderly female patients without adequate trauma. In patients with adequate trauma, MRI is of low value, especially as MRI diagnostics are performed with delay, resulting in later surgery. PMID: 31533165 [PubMed - as supplied by publisher]

Conclusions3D optical imaging of patients with pectus excavatum is emerging as an alternative method to assess HIs without the use of ionizing radiation. Additional studies will focus on volumetric quantification of chest wall deformities, using the 3D capabilities of this technology.

This study aimed to clarify whether CT histogram analysis of tumors can be used to classify patients with clinical stage 0 to IA non-small cell lung cancer according to pathologic lymph node (pN) status.MethodsPredictive factors associated with pN metastasis were identified from the derivation dataset including 629 patients with clinical stage 0 to IA non-small cell lung cancer who underwent complete resection with lymph node dissection (surgeries between 2008 and 2013). The validation dataset including 238 patients (surgeries between 2014 and 2015) were subsequently reevaluated. Clinicosurgical factors, including CT histo...

Authors: Cauley KA, Mongelluzzo GJ, Fielden SW Abstract Identification of early ischemic changes (EIC) on noncontrast head CT scans performed within the first few hours of stroke onset may have important implications for subsequent treatment, though early stroke is poorly delimited on these studies. Lack of sharp lesion boundary delineation in early infarcts precludes manual volume measures, as well as measures using edge-detection or region-filling algorithms. We wished to test a hypothesis that image intensity inhomogeneity correction may provide a sensitive method for identifying the subtle regional hypodensity ...

Conclusion: PSCCT is a rare but aggressive malignancy of the head and neck. Histopathologic and immunohistochemical evaluations are essential for diagnosis. While locoregional surgery and radiation therapy may improve the length of survival, the prognosis of patients with PSCCT is poor. Physicians should be mindful of this unique but deadly disease process, as early diagnosis and rapid treatment initiation are essential to optimize treatment outcomes. PMID: 31528145 [PubMed]

Conclusion: Isolated fractures of the trapezoid require a high index of suspicion as they are rare, and localizing signs and symptoms are typically vague and may mimic those of scaphoid fractures. When athletes present with dorsal wrist pain, swelling, and snuffbox tenderness in the setting of negative plain x-rays, the most likely mechanisms of injury are associated with athletic activity. Treatment depends on the degree of displacement and other associated injuries and ranges from activity modification or immobilization to open reduction with internal fixation. PMID: 31528141 [PubMed]
