Incidental Findings in Paranasal Sinuses and Mastoid Cells: A Cross-Sectional Magnetic Resonance Imaging (MRI) Study in a Pediatric Radiology Department

Abstract The objective of this study was to determine the diagnostic accuracy of B-scan in predicting retinoblastoma (Rb) taking Magnetic Resonance Imaging (MRI) as a gold standard. A cross-sectional validation study was conducted in the Radiology Department of Fauji Foundation Hospital from May 20 to Nov 20, 2017. Children fulfilling the inclusion criteria were selected after informed consent and detailed history was taken for investigation of Rb. B-scan of both eyes was done using 7.5-10 MHz probe, followed by MRI of both eyes in the same patients using 1.5 Tesla MRI machine with the help of qualified MRI technicians. Data analysis was done by SPSS version 16.0. The diagnostic accuracy, sensitivity, specificity, PPV and NPV of B-scan in prediction of Rb as compared to MRI was 90.45%, 82.28%, 90.54% and 90.28% respectively. The study concluded that diagnostic accuracy of B-scan as compared to MRI is substantial in Retinoblastoma. Continuous...

Objective: The objective of this study was to outline a novel unique concept of secondary impingement of the muscles, myotendons, and tendons of the rotator cuff from hypertrophy as a result of strength training exercises. Methods: In this retrospective observational study, 58 patients were referred for an magnetic resonance imaging (MRI) by the orthopedic surgeon to the radiology department over a period of 1½ years. All patients gave a history of strength training exercises and presented with clinical features of rotator cuff impingement. Results: We identified features of hypertrophy of rotator cuff muscles, myotendons, and tendons in 12 of these 58 patients. This was the only abnormality on MRI. The hypertrophy of rotator cuff muscles and tendon bulk completely filling the subacromial space to the point of overfilling and resulting in secondary compressive features. Conclusion: Rotator cuff impingement is a common phenomenon that can occur with various inlet and outlet pathological conditions. However, rotator cuff impingement may also result from muscle and tendon hypertrophy from strength training regimens. Hypertrophy of the rotator cuff can result in overfilling of the subacromial space, leading to secondary impingement, which we have termed as “pseudo-impingement.”

AbstractAnal fistula (AF) is a common referral to colorectal surgeons. Management remains challenging and sometimes controversial. Magnetic resonance imaging (MRI) is commonly performed in initial workup for AF. However, reports often lack key information for guiding treatment strategies. It has been shown that with structured radiology reports, there is less missing information. We present a structured MRI template report including 8 key descriptors of anal fistulas, whose effectiveness and acceptability are being assessed in a cross-sectional study (NCT04541238).

AbstractWe investigated the prevalence of magnetic resonance imaging (MRI) findings and their relationship with knee symptoms in women without radiographic evidence of knee osteoarthritis (KOA). This cross-sectional cohort study included 359 Japanese women without radiographic evidence of KOA (Kellgren‒Lawrence grade < 2). All participants underwent T2-weighted fat-suppressed MRI of their knees. Structural abnormalities (cartilage damage, bone marrow lesions [BMLs], subchondral cysts, bone attrition, osteophytes, meniscal lesions, and synovitis) were scored according to the whole-organ MRI score method. Knee symptoms were evaluated using the Knee Injury and Osteoarthritis Outcome Score. Participants were divided into early and non-KOA groups based on early KOA classification criteria. Logistic regression analysis was performed to evaluate the relationship between MRI abnormalities and knee symptoms. Cartilage damage was the most common abnormality (43.5%). The prevalences of cartilage damage, BMLs, subchondral cysts, bone attrition, meniscal lesions, and synovitis were higher in patients with early KOA than in those without. Synovitis (odds ratio [OR] 2.254, P = 0.002) and meniscal lesions (OR 1.479, P = 0.031) were positively associated with the presence of early KOA. Synovitis was most strongly associated with knee pain and might be a therapeutic target in patients with early KOA.

Study Designs

Objective:To find out whether the neurodevelopmental disorders autism and childhood-onset schizophrenia have a common developmental pathway and whether the abnormalities detected are ‘disorder-specific’, by reviewing magnetic resonance imaging (MRI) studies.Methods:As a result of a Medline search, we were able to access 28 studies on autism and 12 studies on childhood-onset schizophrenia, which focused on children and adolescents.Results:Larger lateral ventricles were found to be a common abnormality in both disorders. ‘Disorder-specific’ abnormalities in patients with autism were larger brains, a larger thalamic area, and a smaller right cingulate gyrus. Subjects with childhood-onset schizophrenia were found to have smaller brains, a smaller amygdalum and thalamus, and a larger nucleus caudatus. In subjects with childhood-onset schizophrenia, abnormalities appeared to progress over a limited period of time.Conclusions:Because the study designs varied so much, the results should be interpreted cautiously. Before abnormalities found in the disorders can be designated as equal or ‘disorder-specific’, it will be essential to perform large longitudinal and cross-sectional follow-up studies.

The role of magnetic resonance imaging (MRI) in predicting disability in multiple sclerosis (MS) remains unclear. In this study 21 patients with primary and secondary progressive MS were reviewed 5 years following a serial MRI study of 6 months duration. In the secondary progressive group (n=11) there was a significant relationship between the occurrence of enhancing lesions and clinical relapses during the initial 6 months and increase in diability 5 years later. For both groups change in disability over the initial study period was predictive of outcome. These results suggest that the presence and frequency of gadolinium enhancement (a marker of inflammation) and changes in disability over a short period are predictive of future deterioration in progressive patients.

SynopsisMany structural brain abnormalities have been described in schizophrenia, consistent with a neurodevelopmental model for this disease. We report here a study of the cavum septum pellucidum (CSP) in schizophrenia compared to control groups, as well as the clinical correlates of this congenital anomaly in schizophrenia. We conducted a magnetic resonance imaging (MRI) study to compare rates of CSP in schizophrenia (N = 67) v. psychiatric controls (bipolar and schizoaffective, N = 60) and healthy controls (N = 37). Of the controls 18·9 %, and of all psychotic subjects 18·1 % had a CSP of any size and there was no difference in the frequency of large CSP among the groups. Males had higher rates of CSP than females (25% v. 9·7%, P = 0·01) in all groups. Schizophrenics had higher CSP rates than affective patients (25%, v. 10%, P = 0·02). No clinical difference was found between schizophrenics with or without CSP.
