Growth prediction in asymptomatic meningiomas: the utility of the AIMSS score

This study aims to validate this score on our series of asymptomatic meningiomas.MethodWe performed a retrospective review of asymptomatic meningiomas diagnosed at our institution between January 2008 and October 2016 and followed by an annual cerebral Magnetic Resonance Imaging (MRI). For each lesion, the AIMSS score was calculated thus classifying them in low (0 –2), intermediate (3–6) or high risk (7–11) of rapid growth (>2cm3/year). We investigated the correlation between the expected Average Growth Rate (AGR) according to the score and the one obtained in our study. The mean growth velocity over the different risk groups was also compared.ResultsOverall, 69 asymptomatic meningiomas found incidentally in 46 patients were included in the study; 31 were assigned to the low-risk group, 34 to the intermediate-risk group and 4 to the high-risk group. Attending to the AGR, 0% showed rapid growth in the low-risk group, 12% in the intermediate-risk group, and 25% in the high-risk group. The mean growth velocity showed a significant difference over the different risk groups (p

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-...

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]

Conclusion: The patient was not treated with the routine therapy used in previously reported cases (curettage), suggesting that antibiotic therapy should be considered before employing surgical interventions for XO. PMID: 31528142 [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]

CONCLUSION: Parasitic diseases, such as those caused by Fasciola hepatica, should be kept in mind in the differential diagnosis of primary or metastatic liver tumors, such as colorectal cancer liver metastasis, in patients living in endemic areas. PMID: 31528248 [PubMed]

In this study, we aimed to compare aortic dimensions on MRI and 2Decho in TS patients. Methods: 50 TS patients (≥18 years) were enrolled into the cross-sectional study. 2Decho and MRI were performed. The measurements of the aorta were assessed in five standard positions on 2Decho and in 9 standard positions on MRI; ASI (aortic size index) of the ascending aorta was calculated since reduced adult height is observed in TS patients. Results: ASI on echocardiography strongly correlated with ASI on MRI in all positions of the ascending aorta, but significantly larger medians of ASI were found on 2Decho in all ...

Duplex ultrasound examination, computed tomography scans, and magnetic resonance angiography have traditionally been used as noninvasive methods to assess carotid stenosis severity. The degree of stenosis in asymptomatic patients has often been used as the main criterion to assess risk for plaque embolization and stroke. There has been an effort to find alternate methods to assess vulnerable plaques. This has included many modalities, including magnetic resonance imaging and other ultrasound techniques.

This review highlights the current state of knowledge about Hashimoto encephalopathy, and progress in the diagnosis and treatment in Hashimoto encephalopathy. Non ‐specific neurological symptoms, laboratory findings and neuroimaging of Hashimoto encephalopathy make its diagnosis an oversight and difficult, whereas antibodies against NH2‐terminal of alpha‐enolase can be useful as a diagnostic biomarker for Hashimoto encephalopathy. AbstractHashimoto encephalopathy (HE) is an autoimmune encephalopathy associated with autoimmune chronic thyroiditis. The clinical entity and nosology of HE have long been debated. Recently...
