Assault-injured youth have an increased risk of future violence. Identifying firearm access among youth in the emergency department (ED) creates an opportunity for interventions aimed at reducing future violent events. We performed this study to determine the extent to which children with assault-related injuries are screened for access to firearms in the ED. We performed a retrospective chart review of all medical records from adolescent ED visits to an academic, tertiary care pediatric hospital in Washington DC with ICD-10 codes related to assault in a 3-month period. We found that among 252 assault-related encounters, none had any documentation of firearm access in the provider note, social work note, or psychiatry consultant note. Therefore, we concluded that firearm access screening is rarely documented in ED visits among patients who present for an assault, highlighting an important missed opportunity for firearm access screening among this high-risk group.

Introduction: The definitive diagnosis of neurocysticercosis continues to be challenging. We evaluate the role of newer magnetic resonance imaging techniques including constructive interference in steady state, susceptibility-weighted imaging, arterial spin labelling and magnetic resonance spectroscopy in the diagnosis of neurocysticercosis., Aims and Objectives: To study the utility of newer magnetic resonance imaging sequences in the diagnosis of neurocysticercosis., Patients and Methods: Eighty-five consecutive patients with neurocysticercosis attending a tertiary care hospital and teaching centre in northern India were included in the study. The diagnosis of neurocysticercosis was made by the Del Brutto criteria. All patients received treatment according to standard guidelines and were followed at 3-month intervals. The following magnetic resonance sequences were performed at baseline: T1 and T2-weighted axial sequences; T2 fluid-attenuated inversion recovery axial sequences; diffusion-weighted imaging; susceptibility-weighted imaging; pre and post-contrast T1-weighted imaging; heavily T2-weighted thin sections (constructive interference in steady state); arterial spin labelling ( n  = 19); and magnetic resonance spectroscopy ( n  = 24)., Results: The mean (±SD) age was 29.4 ± 12.9 years and 76.5% were men. Seizures were the commonest symptom (89.4%) followed by headache (24.3%), encephalitis (9.4%) and raised intracranial pressure (9.4%). Scolex could be visualised in 43.7%, 55.5% and 61.2% of neurocysticercosis patients using conventional, susceptibility-weighted angiography and constructive interference in steady state imaging sequences, respectively. Susceptibility-weighted angiography and constructive interference in steady state images resulted in significantly higher ( P  < 0.01) visualisation of scolex compared to conventional sequences., Conclusion: Newer magnetic resonance imaging modalities have a lot of promise for improving the radiological diagnosis of neurocysticercosis.

Background and Purpose: The cavernous sinus is a unique region owing to anatomical factors and the pathologies affecting it. The diagnosis of cavernous sinus syndrome (CSS) predominantly relies on clinicoradiological correlation. We studied the utility of computed tomographic (CT) scan versus magnetic resonance imaging (MRI) in the diagnosis of CSS., Methods: A prospective observational study was conducted in a tertiary care center in north India. All patients presenting with a clinical syndrome of cavernous sinus involvement with radiologically confirmed lesions were enrolled in the study. MRI and CT scan with cavernous sinus cuts were done and reviewed by experienced neuroradiologists for cavernous sinus lesions and compared with the final diagnosis. Sensitivity and specificity were calculated., Results: We included 48 patients in our study. A final diagnosis was achieved in 41 out of 48 (85.6%) patients. Fungal infections (16 (33.3%)) constituted the commonest cause of CSS, followed by neoplastic involvement (13 (27.1%)) and Tolosa-Hunt syndrome (12 (25%)). Vascular involvement was seen in three (6.3%) patients. Other rare causes were seen in four (8.3%) patients. CT scan had an overall sensitivity of 14.6% in achieving a final diagnosis, whereas MRI had an overall sensitivity of 70.7%, with a statistically significant difference ( p  < 0.001)., Conclusions: Although CT scan is a relatively cheap and accessible resource, its role in CSS diagnosis and management is limited because of poor yield. Hence, it is prudent to do an MRI as an initial investigation in cases of CSS.

Brain metastases are known to be present with a history of increased intra-cranial pressure headache, seizures or altered sensorium. Corresponding to the clinical brain metastases are the most feared complication of a systemic cancer. Classically, brain metastases are associated with significant morbidity and are known to present with a history of increased intracranial pressure headache, seizures or altered sensorium. Neuroimaging is usually suggestive of massive peri-lesional edema and mass effect surrounding the space occupying lesions. This, however it is not a universal rule. We report a 50-year-old gentleman who presented with rapidly progressive forgetfulness. Interestingly, the patient's neuroimaging discretely showed disproportionate involvement with regards to the clinical picture. The lesions were finally recognized as metastases underscoring the importance of an avid search for a primary systemic malignancy if similar findings are noted on radiology.
