Baseball Pitchers

Background: Repetitive pitching produces significant stress on the elbow that may result in structural abnormalities discernable on magnetic resonance imaging (MRI) without causing symptoms. Purpose: To determine whether there exists an association between subclinical MRI findings in asymptomatic elbows of Major League Baseball (MLB) players and future placement on the disabled list (DL) or future operative procedure. Study Design: Cohort study; Level of evidence, 3. Methods: MRI scans of the elbows of professional-level baseball pitchers, taken during routine presigning imaging at a single organization from 2005 to 2017, were retrospectively reviewed. Publicly available databases were queried to exclude pitchers with an injury before the earliest session of elbow MRI. Three blinded reviewers reviewed all MRI scans independently to evaluate for the presence of chondral damage to the joint, loose bodies, ulnar collateral ligament (UCL) heterogeneity or tears, flexor pronator mass defects, and signs of posteromedial (PM) impingement. Binary imaging findings were related to future placement on the DL for elbow complaints and future elbow surgery. Results: A total of 41 pitchers had asymptomatic MRI findings with no prior DL placement. For players who eventually went on the DL, there were a statistically greater number of players with UCL heterogeneity ( P = .021), humeral-sided partial UCL tears ( P = .031), and PM impingement ( P = .004) on preinjury MRI compared with players who remained healthy. PM impingement was related to future elbow-related surgery ( P = .003). Pitchers with UCL heterogeneity were associated with reduced career strike zone percentage, innings pitched, and fastball percentage ( P < .05 for all). Conclusion: UCL heterogeneity, PM impingement, and humeral-sided partial tears were correlated with future DL placement for elbow-related reasons in MLB pitchers. Asymptomatic PM impingement may be a precursor to future surgery.

Background: Vaginal adenosis is a rare clinicopathological entity which refers to the presence of glandular endometrial tissue in the vaginal wall. Case report: A gravida 46-year-old woman was presented to the gynecology department with symptoms of chronic pelvic pain. Maternal Diethylstilbestrol (DES) usage has been proven effective in the development of vaginal adenosis. It can also be idiopathic. Its sonographic or magnetic resonance imaging (MRI) findings have not been described in English literature previously. Conclusion: Here, we report the clinical, transperineal ultrasonographic (US) and MRI findings of a pathologically proven case of vaginal adenosis.

Calcaneal Apophysitis

Calcaneal apophysitis (Sever’s disease), is the most frequent cause of the heel pain in growing children. The diagnosisis generally made with a typical history and clinical examination. Imaging modalities including radiography and magnetic resonance imaging can help establish the diagnosis. In this case we report imaging findings of an 11-year-old boy diagnosed as Sever’s disease.J Nepal Paediatr Soc 2015;35(2):172-174

Background: Approximately 20 per cent of adult patients presenting to otolaryngology clinics have symptoms pertaining to the inner ear. These are investigated with magnetic resonance imaging (MRI) internal auditory meatus scans. This study analysed all findings from 736 sequential MRI internal auditory meatus scans performed on 731 patients over a one year period.Methods: Six hundred and seventy-two patients were included for analysis. Of these, 419 (62.35 per cent) had normal MRI scans, 221 (32.90 per cent) had MRI findings thought to be unrelated to their presenting symptoms, 32 (4.76 per cent) had findings thought to be the cause of their symptoms, and eight (1.19 per cent) had the typical appearance of an VIIIth nerve schwannoma.Conclusions: Magnetic resonance image scanning of the inner ears and auditory pathways yields a diagnosis of VIIIth nerve tumours of the order of 1 per cent, does not show other causes of inner-ear symptoms in a further 4 per cent, and shows incidental intra- and extracranial abnormalities in a further 33 per cent, most of which are not clinically significant.

Background: Magnetic resonance imaging (MRI) is widely used in clinical practice, and “abnormal brain MRI” findings often prompt assessment for multiple sclerosis (MS), even when there are no symptoms suggestive of the disease. Despite several studies involving individuals with “radiologically isolated syndrome” (RIS), little is known about what factors might predict future development of MS. The objective of this study was to longitudinally evaluate clinical and MRI characteristics of people who presented to an MS clinic because of incidental abnormal MRI findings but did not have typical symptoms of MS, in order to assess risk factors for developing MS. Methods: Thirty consecutive patients presenting to an MS clinic for evaluation of abnormal MRI findings were enrolled in the study. Clinical and paraclinical data, including MRI results, were reviewed. Magnetic resonance imaging findings of T2 hyperintensities measuring more than 3 mm in diameter and fulfilling at least three out of four Barkhof criteria, with or without gadolinium-enhancing lesions, were considered to be suggestive of MS. Results: The median follow-up time was 5.5 years. No participants without MRI findings suggestive of MS were diagnosed with MS (P = .005). Fifteen participants had MRI findings suggestive of MS. Seven of the 15 (47%) were diagnosed with MS on follow-up. Cerebrospinal fluid (CSF) testing results were available for 15 participants. Abnormal results were found in six participants, of whom five (83%) also had MRI findings suggestive of MS. Only two of the nine (22%) participants with normal CSF results (P = .04) had MRI findings suggestive of MS. Conclusions: In our cohort, none of the participants without MRI findings suggestive of MS developed MS. The participants with MRI findings suggestive of MS were more likely to develop symptoms and MRI changes typical of MS on follow-up.

Asymptomatic Stage

Natalizumab is a monoclonal antibody against α4-integrin approved for the treatment of multiple sclerosis (MS) due to a positive effect on clinical and magnetic resonance imaging (MRI) outcome measures. However, one relatively rare but serious side effect of this drug is a higher risk of developing progressive multifocal leukoencephalopathy (PML). Since the FDA approval, more than 300 natalizumab-associated PML cases have been documented among more than 100,000 treated MS patients. MRI is a crucial tool in the surveillance of patients treated with natalizumab in order to detect possible signs of PML in the asymptomatic stage. Although classical imaging characteristics of PML are well established, MRI findings in natalizumab-associated PML, particularly in early disease stages, show rather new and heterogeneous imaging findings including different patterns of inflammation with contrast enhancement. This review provides a comprehensive overview of the heterogeneous imaging findings in natalizumab-associated PML in the context of the underlying pathophysiology, histopathology, and the diagnostic procedure. We describe the MRI patterns of PML lesion evolution and complications including immune reconstitution inflammatory syndrome (IRIS). Finally, we present guidelines to differentiate MRI findings in PML from inflammatory demyelinating lesions, to facilitate the early diagnosis of PML in patients treated with natalizumab.

Background: The purpose of this study was to determine whether magnetic resonance imaging findings are accurate and can be confirmed surgically. Methods: Surgical correlation of preoperative magnetic resonance imaging findings of trauma to tendons and ligaments of the foot and ankle were retrospectively studied in 28 patients who had undergone surgical repair for tears of the Achilles tendon, posterior tibial tendon, peroneal tendons, collateral ligaments, and other pathology. Results: This study corroborates that magnetic resonance imaging findings are confirmed surgically 83% of the time for tears of tendons and ligaments of the foot and ankle. Larger tendons (Achilles, posterior tibial tendon) have a 94% sensitivity and 6% specificity, respectively. Collateral ligament and high ankle sprains have a 73% sensitivity. There is a lower sensitivity of 57% for peroneus brevis and longus ruptures. Conclusion: This study revealed that peroneal trauma can be an isolated event and in some cases can occur with other traumatic pathology such as collateral ligament tears.
