Patients with spinal muscular atrophy (SMA) are at risk of poor bone health and fractures. We report a child with SMA type 2, presenting with acute pain and swelling of both lower limbs following physiotherapy, and found to have multiple fractures in both lower limbs. Literature on fractures in children with SMA is limited. Awareness of risk assessment and appropriate preventive measures among healthcare providers caring for children with SMA is essential.
Background: Trigeminal neuralgia (TN) is a debilitating disorder that presents with sudden onset of severe, unilateral, paroxysmal, and lancinating pain usually lasting for few seconds to few minutes. Aims and Objectives: The main aim of our study was to correlate the prepontine cisternal space thickness, with a severity of neurovascular compression (NVC) and percentage reduction of pain (patient outcome). Materials and Methods: Ours is an observational prospective study of 40 patients presenting with TN for magnetic resonance imaging in our department. Patients were followed up on medical treatment and their pain severity evaluated on their follow-up visit. Patients were divided into two groups based on prepontine cisternal space (Group A: ≤4 mm, Group B: >4 mm) and into three groups based on the percentage reduction of pain, Group 1 (0-35%), Group 2 (36-70%), and Group 3 consisted of patients with pain reduction of more than 70%. Ipsilateral prepontine cisternal space thickness was correlated with grade of NVC and percentage reduction of pain. Results: Mean percentage of pain reduction in group A and group B was 34.12 and 60.68%, respectively. Approximately 23.80% of grade1 NVC were seen in group A and 76.20% in group B, while 80% of grade 3 NVC were seen in group A and only 20% were seen in group B. Conclusion: There was poor response to medical treatment, in patients with narrowed prepontine cisternal space thickness with an inverse relationship between the grade of NVC and cisternal space thickness.

Achilles tendon xanthoma is a benign and rare disease with a high incidence in patients having familial hypercholesterolemia. Patients present with or without pain and thickened tendons. Gout is seen in patients with hyperuricemia. Coexistence of xanthoma and gout is extremely rare. We searched the PubMed literature with 'Xanthoma' and 'Gout' as keywords and could find only one case report. Imaging modalities such as radiography and ultrasonography, play a vital role in diagnosing this condition early, hence helping the patient to commence the use of potentially lifesaving lipid-lowering therapeutic agents. Magnetic resonance imaging is helpful in delineating the morphological changes, exact measurements, and eventually in treatment planning. It helps to rule out early involvement of other tendons by the same pathology. We present a case of a 25-year-old male patient who presented to our institute with bilateral large symmetrical swelling in the posterior aspects of ankles for 4 years, with normal serum and blood parameters. Bilaterality, enormous size and normal blood and serum parameters make this case unique.
Systemic cystic angiomatosis (SCA) is a rare disorder, usually involving the visceral organs with incidental detection during its insidious course. On radiography, it can present as multiple cystic lesions. In rare instances, it can present as mixed lesions (lytic, sclerotic) as was the case with our patient. The disease has a better prognosis than most vascular neoplasms involving the bones. We present a rare case of this disease, involving multiple organs, and presenting with an insidious onset.
BACKGROUND: Chest radiographs are the most basic and readily available imaging modality for visualizing the lungs and are potentially useful for describing the disease severity in patients showing respiratory symptoms in COVID-19 patients. The early diagnosis of COVID-19 features on radiography helps in triaging and starting treatment. MATERIAL AND METHODS: Our study consisted of 145 radiographs, and these were reported by two radiologists, two emergency physicians and one intern working in the Emergency department. The scores given by them were correlated. A targeted short lecture for the scoring was imparted and after a sufficient latent period the scoring of chest radiographs was done again, and the scores correlated and compared. RESULTS: We observed agreement between radiologists with emergency medicine physicians was "none to slight" to "fair," before the dedicated online teaching course. Following the meeting, there was an increase in interobserver agreement in-between radiologists and between radiologists and emergency medicine physicians. CONCLUSIONS: We propose a focused online meeting, targeted at explaining radiological features of a specific pathology, in a pandemic situation like COVID, to our clinical counterparts in the emergency medicine department can help in increasing their interpretation skills. This can directly benefit triaging, admission/discharge and monitoring of the status of patients, in intensive care units and emergency medicine. This also helps in allaying the anxiety, while waiting for a final report from the Radiologist.
Background Neurovascular conflicts (NVCs) are one of the major causative factors in patients presenting with trigeminal neuralgia (TN). We found a wide range of variation in degrees of acute angle formed between medial border of trigeminal nerve and anterior border of pons in patients with TN, i.e., medial trigeminopontine angle (mTPA), and tried to find its correlation with pain severity due to NVC over the medial aspect of nerve (mNVC). Aims and Objectives To correlate mTPA measurement with severity of TN due to mNVC. To calculate the reduction in pain in patients kept on medical management and its correlation with mTPA. Materials and Methods This was a retrospective observational study conducted between May 2018 and October 2020. A total of 41 patients presenting with TN and showing corresponding NVC were included in the study. Out of the total cases with NVC, 30 cases showed NVC over the medial surface of the nerve. All the patients were evaluated on MAGNETOM Skyra 3T magnetic resonance imaging (MRI; Siemens). Using the two-line Cobb angle method, the trigeminopontine angle was calculated. Pretreatment pain intensity and posttreatment pain relief of each patients were assessed by using the numeric rating scale (NRS) with numbers from 0 to 10 ("no pain" to "worst pain imaginable"). Relevant clinical details regarding pre- and posttreatment pain score, after a standard treatment plan of 600 mg of oxcarbazepine for 2 weeks, were collected. Results Patients showing response of more than or equal to 50% (≥50%) are considered as "good response" and those with response of less than 50% (<50%) are considered as "poor response." In our study with trigeminopontine angle threshold of 45 degrees, 7 out of 8 (87.5%) patients with >45° mTPA showed poor response and 15/22 (68.2%) patients with ≤45° showed good response to medical management for TN with statistical significance difference with a p -valve of 0.007. Conclusion We found a negative correlation between the mTPA and percentage pain relief in patients kept on medical management and realized that mTPA measurement could become an important tool for prognosticating pain relief for patients of TN on medical therapy; however, more evidence and multicentric studies are required for the same.
During the COVID-19 pandemic, differences in health-care system and policies among countries worldwide meant that each country had to come up with their own strategies for containment, diagnosis, and treatment of the disease - "no one size fits all." India being the second populous country in the world with modern and traditional systems of health care has its own challenges to face during the pandemic. Among the increased cacophony of information regarding the COVID-19 disease and controversies surrounding the usage of various radiological modalities for its diagnosis, we are trying to present a sane perspective from an Indian radiologist viewpoint. Knowing the strengths and shortcomings of the Indian health-care system, we have suggested plausible solutions which may be the answers to the issues raised by the Indian media.

Synovial osteochondromatosis is a rare benign pathology arising from the synovial membrane of the joints, synovial sheaths or uncommonly the bursae around the joints. Baker's cysts are fluid filled, synovium-lined lesions arising in popliteal fossa. Synovial chondromatosis involving the Baker`s cyst is extremely rare. The aim of this case report is to document this exceedingly rare extra articular synovial pathology involving Baker's cysts of bilateral knees and to emphasize the importance of radiographs and sonography in the diagnosis.
BACKGROUND: Parkinson's disease is associated with significant changes in morphometry of subthalamic nucleus (STN); however, not much is known as the disease progresses. The aim of present study was to investigate the volume of STN and Red nucleus (RN) on 3T-magnetic resonance imaging (MRI) and its possible correlation with disease progression in advanced Parkinson's disease patients. METHODS: Patients of advanced Parkinson's disease were prospectively followed for clinical details, motor severity scores, and radiological evaluation. Volumes of the STN and RN were measured on susceptibility weighted imaging, coronal sections in 3T MRI and were correlated with demographic and clinical features. RESULTS: A total of 52 patients were included in our study. There were 42 (80.77%) males and 10 (19.23%) females. Mean age of onset of Parkinson's disease was 49.48 + 10.90 years. Average duration of disease in the present cohort was 7.65 + 4.31 years. Average STN and RN volume were 103.46 + 21.17 mm3 and 321.73 + 67.66 mm3. Age of onset, disease duration and Unified Parkinson's Disease Rating Scale Part III scores were not found to be associated with changes in STN Volumes. Weak positive trend was noted between RN volume and disease duration (Pearson cor. 0.204, P = 0.14). Patients in early-onset Parkinson's disease group had significantly more volume of RN than patients in late-onset Parkinson's disease group (P = 0.014). CONCLUSION: Disease duration and early age of onset in Parkinson's disease can be associated with increased RN volume. Volume of STN shows relatively no change even with disease progression.
BACKGROUND: Inadequate serum vitamin D levels are associated with secondary hyperparathyroidism, increased bone turnover, bone loss and increased fracture risk. Vitamin D is well recognized to be suboptimal in older patients when compared to age-matched controls. There are no published studies on the prevalence of hypovitaminosis D in Indian population with fragility fractures around the hip associated with osteoporosis and comminution at the fracture site. AIM: To investigate the prevalence of hypovitaminosis D in patients admitted with osteoporotic hip fractures and associated fracture site comminution in a South Indian Institute. MATERIAL & METHODS: A prospective cross sectional study was conducted on 100 patients admitted with osteoporotic hip fracture. Measurement of serum 25-hydroxy vitamin D was done and the same was correlated with the degree of osteoporosis using Singh's index and fracture site comminution. RESULTS: Out of 100 patients studied, 92% had hypovitaminosis D with mean vitamin D level of 16.08⯱â¯5.95â¯ng/dl (65% vitamin D deficiency with mean 13.16⯱â¯4.24â¯ng/dl and 27% vitamin D insufficiency with mean 23.11⯱â¯2.62â¯ng/dl) and 94% had osteoporosis with Singh's index grade 3 or less. Out of the 36 patients with fracture site comminution 34 patients (94%) had hypovitaminosis D and 33 patients (91.6%) had osteoporosis. Statistical significance was established for all the variables. CONCLUSION: Significant association was found between hypovitaminosis D, osteoporosis and fracture site comminution. High prevalence of hypovitaminosis D in patients presenting with hip fractures and fracture site comminution implicates the necessity for proper evaluation and effective supplementation of vitamin D in elderly patients along with anti-osteoporotic regimens for effective prevention and appropriate management of osteoporotic hip fractures.
BACKGROUND: Whole-body computed tomography (WBCT) is used indiscriminately in trauma cases, just on the suspicion of them being polytrauma cases. A good clinical examination done pre-emptively could prevent the need for this investigation and its undesirous effects. We did this study with an overall aim to assess, if WBCT can be limited to subgroup of trauma patients without compromising clinical safety. METHODS: Retrospective database analysis of 150 cases of polytrauma who underwent WBCT in 2017 was performed. We recorded age, gender, radiation dose and CT findings in all cases and calculated mean age, number of total patients and female patients less than 25 years of age, number of normal WBCT scans, mean radiation dose in the normal and total scans. We also compared pre-test clinical requests with whole-body CT findings, and categorised them in following seven categories: Category 1-Normal Scans; Category 2-Clinically expected Major Injuries; Category 3-Clinically expected Minor Injuries (low risk injuries with no risk of morbidity or mortality if remained undiagnosed), Category 4-Clinically expected CT findings with unexpected Minor (non-serious) injuries; Category 5-Clinically expected CT findings with unexpected Major (serious) injuries, Category 6-Unexpected Minor (non-serious) injuries; Category 7-Unexpected Major (serious) injuries. Categories 2 &3 of clinically expected major and minor injuries included patients with fewer injuries than expected. On the other hand, Category 4 & 5 consist of clinically expected findings with other unexpected injuries, including minor and major injuries respectively. Body injuries were reported in seven areas as per our institutional reporting protocol- Head (including face), Cervical Spine, Thoracolumbar Spine, Chest, Abdomen, Pelvis and Appendicular Skeleton (if asked for). RESULTS: Overall, we found statistically significant correlation between clinical suspicion raised and WBCT findings with good clinical correlation noticed in 106 (70.66%) cases (including 61 cases of clinically suspected major injuries, 15 cases of clinically suspected minor injuries and 25 nearly normal scans with no obvious clinical concern). Isolated unexpected serious injury without any clinical suspicion was seen in only 1 case. Surprisingly, 25 scan requests were made due to high risk mechanism of injury with no obvious clinical concern and were found normal in 20 cases and showed very subtle injuries in 5. Notably, 30 cases of expected major and minor injuries showed highly accurate clinical findings with no injury other than the region of concern and in these cases, limited scan requests would have been sufficient. Mean radiation dose of the entire study group was 22.45 mSv and those to normal patients was 21.19 mSv. CONCLUSIONS: This study re-emphasizes the significance of good clinical examination in the era of evidence based medicine, which would reduce the high number of unnecessary high dose WBCT (25 scans with no positive findings on clinical examination were nearly normal and in 30 cases limited CT would have been sufficient), thereby, decreasing radiation exposure and its potential side effects on polytrauma patients without affecting their survival.
Tracheal septum has never been reported in human beings, though it's a common occurrence in few lower vertebrates. We are presenting a case of thick tracheal secretion that appeared as a midline tracheal septum and prompted the clinician to go for bronchoscopy.
Ossification of the Achilles tendon is a rare clinical entity comprising of one or more segments of variable sized ossified masses in the fibrocartilaginous substance of the tendon. The etiology of ossification of the Achilles tendon is multifactorial with recurrent trauma and surgery comprising major predisposing factors, with others being metabolic, systemic, and infectious diseases. The possibility of a genetic predisposition towards this entity has also been raised, but has not yet been proven. We present a rare case of ossification of the bilateral Achilles tendons without any history of trauma or surgery in a 48-year-old female patient.
Lipofibromatous hamartomas are rare benign tumours of Peripheral nerves. Median nerve is most common affected nerve involved in about 80 percent of the cases. Approximately 92 cases have been reported so far. We present a case of lipofibromatous hamartoma of median nerve diagnosed on sonography and magnetic resonance imaging (MRI). These rare lesions are an important entity to be known to radiologists because their imaging features are quite pathognomonic and allow for confident diagnosis negating the need for biopsy.
Authors describe diagnostic dilemma of differentiating pyelonephritis with lymphomatous involvement of kidney in a known case of lymphoma. FDG uptake pattern was non-discriminatory and pyelonephritis diagnosed retrospectively on follow up study. Authors emphasize the importance of recognition of features and subtle clues of infection evident on CT component of PET-CT.
