BackgroundPre-operative assessment of middle ear cholesteatoma is a must for assessing the disease's location, extent, and complication, and high-resolution computed tomography (HRCT) is the modality of choice. Therefore, this study aims to assess the common signs of cholesteatoma on HRCT and its diagnostic ability. MethodsFifty patients with suspected cholesteatoma were considered for the study, which was carried out on an Ingenuity Core 128 slice CT scanner (Philips, Amsterdam, Netherlands). The bilateral temporal bones of 50 patients were assessed for soft tissue density and associated findings. The number of temporal bones with soft tissue density was then correlated with intra-operative and histopathological examinations (HPE). ResultsOut of 100 temporal bones, 63 were diseased, and 37 were normal temporal bones. Epitympanum/Prussak's space was the most involved site with soft tissue density seen in 60/63 (95.2%) diseased temporal bones, followed by aditus ad antrum and mesotympanum, which was seen in 51/63 (80.9%) diseased temporal bones. The majority of the soft tissue lesions were non-dependent, accounting for 43/63 (68.2%) of the diseased temporal bones. Bony erosions were seen in 54/63 (85.7%) and bony expansion in 35/63 (55.5%) of the diseased temporal bones. HRCT showed a sensitivity of 100%, specificity of 88.1%, a positive predictive value (PPV) of 92.1%, a negative predictive value (NPV) of 100%, and accuracy of 95% for detection of cholesteatoma. ConclusionHRCT of the temporal bone precisely demonstrates cholesteatoma's location, extent, and bony changes. Therefore, it has exceptional sensitivity, high specificity, and accuracy in diagnosing cholesteatoma.
Background: Beta-thalassemia is a group of inherited blood disorders that are characterized by reduced levels of functional hemoglobin. These patients require lifelong blood transfusions, leading to iron deposition in various tissues. Prompt detection of myocardial iron helps to assess the extent of myocardial damage and its complications. Aims and Objectives: Our study aims to establish the role of T2* cardiac magnetic resonance imaging (MRI) and its comparison with serum ferritin levels in detecting iron overload in beta-thalassemia major (TM) patients. Materials and Methods: This prospective study included 30 pediatric patients admitted to our institute with beta-TM. The patients underwent T2* cardiac MRI examinations, myocardial iron quantification was assessed, and patients were divided into groups based on the severity of iron overload. Results: In this study, there were 18 males and 12 females. Out of the total studied cases, 15 (50%) showed no evidence of iron overload, 8 (26.67%) showed mild, 4 (13.33%) showed moderate, and 3 (10%) showed severe cardiac siderosis, based on the cardiac T2* values obtained. Conclusion: T2* cardiac MRI is an accurate and invaluable tool that helps to detect iron overload in beta-TM.
Ectopic thyroid gland occurs due to aberrant descent of primitive thyroid gland to the final pre-tracheal position and failure of fusion of thyroid anlages. Submandibular ectopic thyroid is a rare thyroid anomaly that can present with or without an orthotopic thyroid gland. We present a case of a young female with hypothyroidism and left submandibular swelling demonstrated to be an ectopic thyroid with the colloid nodular goitre on imaging and cytology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
