Role of Magnetic Resonance Imaging in the Evaluation of Trigeminal Neuralgia Using Steady-State Imaging.

Trigeminal neuralgia (TN) poses diagnostic challenges due to its complex origins, often associated with neurovascular compression. Advanced imaging techniques, particularly magnetic resonance imaging (MRI) with the fast imaging employing steady-state acquisition (FIESTA) sequence, offer crucial insights into TN pathophysiology. This prospective cross-sectional observational study aimed to elucidate MRI's utility in diagnosing TN and correlating imaging findings with clinical manifestations and treatment outcomes. A cohort of 41 patients clinically suspected of TN underwent MRI evaluation at Acharya Vinoba Bhave Rural Hospital, Sawangi (Meghe), Wardha, utilizing various sequences including FIESTA. Analysis revealed a higher incidence among females, predominant unilateral presentation, and a higher prevalence of abnormal MRI findings, with neurovascular compression as the leading etiology. Correlation analysis demonstrated significant associations between facial pain localized to the trigeminal nerve distribution, triggering factors, and abnormal MRI findings. Gender distribution did not significantly influence MRI findings. Treatment outcomes favored microvascular surgery over conservative management in cases of neurovascular compression. This study underscores MRI's pivotal role, particularly FIESTA, in TN evaluation, guiding personalized treatment strategies and emphasizing the importance of integrated clinical and imaging approaches. Further research is warranted to validate these findings and explore additional imaging modalities for a deeper understanding of TN pathogenesis.

Magnetic Resonance Imaging of Radiation-Induced Brachial Plexopathy.

This report illustrates the case of a 37-year-old woman following chemoradiotherapy for invasive ductal carcinoma of the right breast. The patient underwent surgery and received a radiation dose of 50 gray to the chest wall and 45 gray to the regional lymph nodes in 25 total fractions. She developed motor and sensory weakness in the right upper limb eight years after treatment. Brachial plexus neuropathy in cancer patients may result from either trauma to the plexus during surgery, the spread of cancer, or radiation therapy, and distinguishing between them may be difficult. The case highlights the importance of recognizing the signs, symptoms, and possible differential diagnosis of radiation-induced brachial plexopathy in cancer patients post-radiation therapy. It emphasizes the role of magnetic resonance imaging in the careful assessment and diagnosis of such a case.

Building a Trauma-Informed Community: Applying Community Building Circles to an Academic Health Research Setting.

PROBLEM: Within health science disciplines, power dynamics exist that can not only perpetuate harm but also foster feelings of powerlessness and disengagement. Although diversity, equity, and inclusion approaches have been prioritized by many institutions to improve student and staff recruitment, few effective structures exist to promote the retention, support, and inclusion of these individuals. APPROACH: Restorative justice circles facilitate a collaborative and personal exercise that welcomes the input of all members, thus acting as a catalyst toward broader and more deeply rooted culture changes and conflict resolution. Restorative justice circles can be applied to strengthen academic learning environments by building community and creating intentional dialog spaces to promote accountability and belonging. The Phoenix Gender-based Violence Lab is an interdisciplinary health research lab composed of diverse researchers who meet monthly for a restorative justice-inspired community-building circle and discussion. The lab members participated in community-building circles from August 2021 to August 2022 during which circle facilitators aimed to prioritize safety, trustworthiness, and transparency and provide collaboration opportunities. OUTCOMES: All 10 research team members consented to an anonymous evaluation survey to share their perspectives about incorporating this approach into lab time. Research team members expressed many benefits of circle discussions, including mitigated power dynamics (n = 5), increased lab cohesion (n = 9), improved research processes (n = 6), and enhanced honesty and accountability (n = 4). NEXT STEPS: Circle practice has shown promising results within the Phoenix Gender-based Violence Lab, indicating that other academic and medical settings should consider its potential to enhance group dynamics, foster accountability, and cultivate deeper collaboration and appreciation among group members. Further investigation of circle practice in diverse medical and academic settings is needed to fully comprehend the range of outcomes resulting from this intervention and whether they align with the fundamental principles of restorative justice.

In conclusion, high-resolution imaging is an indispensable tool, continually advancing to meet the diagnostic and therapeutic needs of individuals grappling with shoulder joint pain.

A Case of Phlebectasia in a Child Presenting With Neck Mass.

Jugular phlebectasia is an enlargement of the jugular vein that manifests as a soft, cystic lump in the neck which can be compressed, becomes prominent on crying or straining and disappears on rest. It needs to be distinguished from laryngocele, neck cysts, and tumours that can also develop with straining. We report a case of a seven-year-old boy presenting with a cervical cystic mass. Comparable computed tomography and ultrasonography findings helped identify the pathology.

Complex Closed Spinal Dysraphism Presenting As Cauda Equina Syndrome With Faun Tail Nevus.

A posterior midline cutaneous lesion known as a faun tail nevus or aberrant lumbar hypertrichosis is significant to doctors because it may serve as a cutaneous signal for an underlying spinal cord and spine abnormalities. We describe a 17-year-old child who, since infancy, has had excessive hair development over his lumbosacral area. The lower spinal cord was affected by a related spinal abnormality. Clinical evidence was used to make the diagnosis. The patient presented with complaints of asymmetric monoparesis which on clinical examination and radiological investigations was found to be cauda equina syndrome secondary to spina bifida occulta. This case is reported for its clinical importance as patients with spina bifida occulta may show late deterioration.

A Comprehensive Review on the Diagnosis of Knee Injury by Deep Learning-Based Magnetic Resonance Imaging.

The continual improvement in the field of medical diagnosis has led to the monopoly of using deep learning (DL)-based magnetic resonance imaging (MRI) for the diagnosis of knee injury related to meniscal injury, ligament injury including the cruciate ligaments, collateral ligaments and medial patella-femoral ligament, and cartilage injury. The present systematic review was done by PubMed and Directory of Open Access Journals (DOAJ), wherein we finalised 24 studies conducted on the accuracy of DL MRI studies for knee injury identification. The studies showed an accuracy of 72.5% to 100% indicating that DL MRI holds an equivalent performance as humans in decision-making and management of knee injuries. This further opens up future exploration for improving MRI-based diagnosis keeping in mind the limitations of verification bias and data imbalance in ground truth subjectivity.

A Systematic Review of the Role of Magnetic Resonance Imaging in the Diagnosis and Detection of Neurovascular Conflict in Patients With Trigeminal Neuralgia.

Trigeminal neuralgia (TN) is a debilitating disorder causing severe, episodic, unilateral stabbing facial pain disturbing enough to disrupt the activities of daily life. Classic TN is caused due to compression injury of the trigeminal nerve at the cistern segment caused by either an artery or a vein, referred to as neurovascular contact or conflict (NVC). Magnetic resonance imaging (MRI) has been the standard tool for the diagnosis of NVC. This study aimed to determine the incidence of NVC in TN, as identified by MRI, assess the various MRI grading patterns among patients with TN, and identify the vessels primarily involved in NVC. A systematic search of studies that used MRI for the diagnosis of TN in reference to NVC was conducted on DOAJ and PubMed/PubMed Central. Data were extracted and entered into a Microsoft Excel spreadsheet. The outcomes measured were the incidence of NVC as shown in MRI, vessels involved in NVC, and MRI grading patterns. We identified and selected 20 studies that fulfilled inclusion/exclusion criteria. In total, 1,436 patients were enrolled in all included studies. The type of MRI used was 1.5 T or 3 T MRI. The mean age of the patients varied from 49 to 63 years, with an equivalent male-to-female ratio. NVC was seen in 1,276 cases out of 1,436 cases (88.85%) of TN on the ipsilateral side, as shown by MRI. The vessels involved were arteries in 80-90% of the cases, followed by veins. Among the arteries, the superior cerebellar artery was the most common artery (80-90% of cases). The grades of NVC as assessed by MRI included grades I, II, and III with varied proportions in different studies. NVC is a common problem in TN, wherein there is compression at the nerve root entry zone, and it shows a strong predilection for the elderly population. MRI seems to be a novel imaging diagnostic investigation to identify NVC associated with TN. Moreover, NVC grading must be done with MRI so that it may help the surgeon in stratifying the patient's treatment.

Lipoma Arborescens Where MRI Is a Boon.

Lipoma arborescens is a slow-progressing intra-articular benign lesion that typically affects the knee joint's suprapatellar recess. It occurs due to lipomatous proliferation of the synovium, giving a characteristic frond-like appearance. It is a rare cause of intermittent knee pain and joint effusion. We draw attention to this rare condition to increase the knowledge of its clinical symptoms and imaging characteristics, allowing for an early diagnosis and appropriate management. Magnetic resonance imaging (MRI) is considered the initial and the single imaging modality to evaluate this condition in the current era.

Adamantinoma: An Uncommon Cause of Bone Pain in a Young Adolescent Male.

Adamantinoma, an uncommon low-grade primary malignant bone tumor, rarely causes leg pain in adolescents and typically manifests in the lower extremities, with a notable preference for the tibia, although occurrences in other bones such as the femur, fibula, and pelvis have been documented. Instances of local recurrence and regional metastasis are infrequent. This case report aims to comprehensively review the clinical presentation, imaging features, histological findings, and management of adamantinoma. The presented case involves a 17-year-old male patient with a four-year history of edema and discomfort in the right anterior leg. Radiographic examination of the proximal tibia revealed a well-defined, expansile lytic-sclerotic lesion with multiple septae and a partially sclerotic border. Subsequent magnetic resonance imaging (MRI) confirmed the nature of the lesion, and a biopsy, followed by histological analysis, confirmed the diagnosis of adamantinoma. This case highlights the significance of a multidisciplinary approach, emphasizing close collaboration among radiology, pathology, and orthopedic oncology in adamantinoma management. Long-term follow-up is imperative for monitoring recurrence and administering timely therapy. The objective of this case report is to contribute to an improved understanding of adamantinoma and offer guidance on the treatment of this uncommon bone tumor.

Large Unruptured Perineal Epidermoid Cyst: A Rare Case.

Perineal epidermoid lesions are uncommon, with only a few research papers accessible on the subject. Because these lesions are varied in origin and can range from benign to malignant, it can be difficult to tell them apart. A wide variety of lesions are evaluated in the differential diagnosis of perineal cystic lesions, however perineal epidermoid cyst is uncommon. An epidermoid cyst is a benign ectodermal congenital abnormality. Epidermoid cysts can be found all over the body, however, they are uncommon in the perineal area. We discuss a case of a perineal epidermoid cyst in an adult female presenting to the general surgery department with painful perineal swelling. The patient was advised for an ultrasound (US) and MRI for further evaluation and the findings are reported.

Post-COVID-19 Myositis Based on Magnetic Resonance Imaging: A Case Report.

The severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) causes COVID-19, which is known to cause fever, dry cough, exhaustion, headache, and loss of taste and smell. Although fever, sore throat, and cough have historically been the utmost characteristic symptoms of the illness, published case reports have recently started to emphasize additional uncommon and unusual presentations of infection with the coronavirus. In COVID, the musculoskeletal system is seldomly involved. In addition to reviewing the causes and imaging characteristics of COVID-19-related illnesses of the musculoskeletal system, we elaborate on a case of a middle-aged man who developed myositis as sequelae to the COVID-19 infection.

Injectable cultured bone marrow derived mesenchymal cells vs chondrocytes in the treatment of chondral defects of the knee - RCT with 6 years follow-up.

Articular cartilage has unique biological and biomechanical characteristics. Damage to this tissue fails to heal spontaneously, leading to progressive arthritis. Cartilage repair techniques have been looked forward to in the treatment of significant cartilage injuries. Cell-based regenerative techniques like the two-staged cultured chondrocytes and single-stage mesenchymal cell transplantation have been tried with varying results and limitations. We study the outcomes of cultured bone marrow derived MSCs in the treatment of articular cartilage defects of the knee in comparison to autologous cultured chondrocyte implantation (ACI). Both cultured MSC and ACI treatment methods resulted in significant improvements in patient reported outcome measures (PROMs). There was no difference in the PROMs, MOCART scores, T2∗ mapping and dGEMRIC values between the groups. Use of cultured MSCs leads to good clinical outcomes similar to ACI and represents a promising treatment to restore the articular cartilage in the knee.

Giant Abdominal Pseudoaneurysm Secondary to Recurrent Pancreatitis: Imaging and Endovascular Intervention.

Chronic or necrotizing pancreatitis is characterized by repeated inflammation of the pancreas, leading to multiple complications, a few of which are vascular, such as splanchnic venous thrombosis and arterial pseudoaneurysms. Even though the frequency of pseudoaneurysm formation in patients with pancreatitis is as high as 10%, there is not much importance given to its management in the radiologic literature. The splenic artery is the most common visceral artery affected by pseudoaneurysms, followed by the gastroduodenal and pancreaticoduodenal arteries. Usually, pseudoaneurysms occur due to the erosion of a peripancreatic or pancreatic artery into a pseudocyst, but this can also occur without the development of a pseudocyst. Pseudoaneurysms may be asymptomatic (usually the ones less than 5 cm), but some of them may pose a threat due to spontaneous rupture and subsequent fistulization into other organs. Therefore, early diagnosis and management are of prime importance. Here, in this article, we present a case of pseudoaneurysm of the gastroduodenal artery with characteristic imaging features and preferred, recent techniques of management.

Intracranial Rosai-Dorfman Disease: A Case to Remember.

Sinus histiocytosis with massive lymphadenopathy (SHML), an alternative term for Rosai-Dorfman disease (RDD), is a rare benign idiopathic immune-related lymphoproliferative condition. The central nervous system (CNS) has been documented to be involved in RDD, although lymph nodes are the organs that are most frequently and primarily associated with the disease manifestation. Nonetheless, CNS involvement in RDD is rare and poorly understood. As a result, there is a lack of a solid basis for therapeutic approaches for CNS involvement in RDD. Here, we present a case of RDD with cerebral involvement, a rare presentation of RDD with atypical symptoms. A brief assessment of the radiographic appearance, histological findings, and the peculiar manifestations of the disease is provided.

Articular cartilage repair & joint preservation: A review of the current status of biological approach.

The articular cartilage of the joint is the thin viscoelastic layer of the connective tissue. It has a unique anatomy and physiology, which makes the repair of the articular cartilage damage more difficult and challenging due to its limited healing capacity. Increasing knowledge regarding the importance of articular cartilage for joint preservation has led to increased attention on early identification of cartilage damage as well as degeneration in order to delay osteoarthritis. There are various treatment modalities ranging from preventive management, physical therapy, pharmacological, non-pharmacological and surgical treatments exist in current literature. However most of the studies have limited long term follow up and mainly consists of small case series and case reports. This is an up to date concise review discussing the available management options for articular cartilage damage starting to lifestyle modification to pharmacotherapy, physiotherapy, and osteobiologics till various joint preservation techniques that have been in use currently.

Articular cartilage repair using autologous collagen-induced chondrogenesis (ACIC): a pragmatic and cost-effective enhancement of a traditional technique.

PURPOSE: The autologous collagen-induced chondrogenesis technique is described, and the results of a 6-year follow-up clinical study using this technique are presented. METHODS: 30 patients with International Cartilage Repair Society (ICRS) Grade III/IVa symptomatic chondral defects of the knee treated with enhanced microdrilling using atelocollagen were prospectively examined in this clinical series. The median age of the patients was 39.0 years (range 19-61 years). Patients were followed up to 72 months. Clinical evaluation was performed using functional knee scores and radiologically. Both quantitative and qualitative assessments were performed. RESULTS: Statistically significant and clinically relevant improvement was observed in 2 years and was sustained for the 6 years of the study observation. At 6 years, the mean Lysholm score was 79.7 (SD 6.8) compared to 52.6 (SD 10.7) pre-operatively (p < 0.05). The symptomatic Knee Injury and Osteoarthritis Outcome Score (KOOS) improved from 68.3 (SD 11.4) to 90.2 (SD 4.3) (p < 0.05). The subjective International Knee Documentation Committee (IKDC) also showed improvement from 39.1 (SD 4.1) to 81.6 (SD 7.8) (p < 0.05). The calculated T2* relaxation times were 26.0 (SD 4.2) seconds and 30.3 (SD 6.2) seconds for the repair tissue and native cartilage, respectively. The average magnetic resonance observation of cartilage repair tissue (MOCART) score was 78.5 (SD 9.6) for all lesions. CONCLUSION: The enhanced microdrilling using atelocollagen is an enhancement of the traditional microfracture method using an off-the-shelf product. When used to treat moderate to severe chondral lesions, this enhancement produces hyaline-like cartilage with a corresponding improvement in symptoms. LEVEL OF EVIDENCE: IV.
