It has two major subtypes Crohn’s disease and ulcerative colitis. The follow-up consists of radiologic, molecular, endoscopic, and histological assessments. Intestinal ultrasound (IUS) is a noninvasive measure that provides future hope in guiding the management of IBD patients. This study is to assess the effectiveness of IUS in IBD patients’ follow-up in our tertiary center during the pandemic. This is a prospective observational study during the COVID-19 pandemic. We used IUS to assess activity of IBD at baseline and at 6-month follow-up of patients on maintenance biological therapy using the following parameters: bowel haustrations, stratification, bowel wall thickness (BWT), Doppler sign (Limberg classification), presence of lymph nodes, or fibrofatty infiltration, echogenicity of the bowel, and presence of fistulae or abscesses. We compared the IUS with other radiologic parameters, histologic, and endoscopic scores at baseline before therapy, while we compared IUS with clinical scores and laboratory parameters before and after 24 weeks of biological treatment. The cohort included 50 known IBD patients from June 2021 to January 2022. The laboratory studies showed a significant improvement in the hemoglobin indices, CRP, and fecal calprotectin from baseline and after 24 weeks. BWT, lumen diameter, lymph node presence, inflammatory signs, and Doppler activity signs were the most significant parameters in detecting improvement. However, there was no significant correlation between fecal calprotectin levels and ultrasound parameters. There was a positive correlation between MR and CT enterography, endoscopic parameters, and IUS parameters at baseline. IUS is an effective tool for follow-up of IBD patients especially during the pandemic periods.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although they arise mostly from retroperitoneal major vascular structures, some encountered cases may arise from the smaller vascular structures of the thigh as the femoral vein. Due to their origin from the vascular structures, they represent a diagnostic challenge as they may be misdiagnosed as deep vein thrombosis (DVT). We present a case of a 45-year-old woman with left femoral and iliac vein LMS that was previously described in the vascular ultrasound (US) report as extensive DVT involving the femoral and external iliac veins. The patient did not improve after receiving the prescribed anticoagulants. Seven months later, the patient underwent computerized tomography (CT) with contrast, revealing a soft tissue mass in the anatomical site of the left common femoral and external iliac veins. The patient underwent both US-guided tru-cut biopsy and incisional biopsy from the iliac lymph nodes which revealed leiomyosarcoma. The patient underwent both vascular ultrasound and magnetic resonance imaging of the pelvis and the left thigh at the time of the first presentation. Seven months later, she underwent contrast-enhanced CT of the abdomen and pelvis. The patient was referred to the oncology department to receive the appropriate chemotherapy protocol as the tumor was inoperable. Although leiomyosarcoma of vascular origin is a rare entity of neoplasms, it is usually underestimated. A high index of suspicion would help the clinician to suspect such a neoplasm and save time for early diagnosis and management. Special caution should be taken for patients with venous thrombosis not improving on anticoagulants. When there is suspicion, other modalities such as computerized tomography and magnetic resonance imaging help confirm the diagnosis.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pulmonary arterial hypertension is common in patients with idiopathic pulmonary fibrosis, the presence of PAH is linked to higher mortality rates and might explain why some people who otherwise have normal pulmonary function are displaying symptoms of deterioration. The aim of this work was to find out the potency of integration of high-resolution computed tomography (HRCT) scoring system with pulmonary artery systolic pressure (PASP) for ascertaining the disease severity of patients with idiopathic pulmonary fibrosis and to predict the prognosis for proper management, along with incorporation of the key disparity of different HRCT scoring systems for the ILD. This prospective study included 80 patients, who came with idiopathic pulmonary fibrosis. A strong positive correlation (r = 0.989) was noted between total lung zone HRCT score and PASP, pulmonary artery size, grades of dyspnea and PCO2. Nonetheless, total lung zone HRCT score proved to have good correlation and inversely proportional to (r = − 0.71) 6MWT, PO2, SPO2, FVC and FEV1/FVC. We utilized a ROC curve to identify the optimal cutoff value in HRCT scoring systems, for detecting pulmonary hypertension associated with the IPF. The sensitivity and specificity of Warrick score cutoff value was higher compared to that of the HRCT scoring system-based grading scale. Both HRCT scoring systems attained high correlation coefficient factors with various incorporated parameters in the study. We can safely say that in order to reveal the severity and prognosis of idiopathic pulmonary fibrosis, a high-resolution computed tomography scoring system should be incorporated with echocardiography measurement of pulmonary artery systolic pressure —which proved to be the most potent predictive factor; especially when measured after a specific HRCT score cutoff value—followed by (FEV1/FVC), the 6MWT and the severity of dyspnea. Their integration collectively will aid in precise management and follow-up of IPF cases. Both HRCT scoring systems proved to be potent and perfect for short-term interval follow-up, yet the Warrick score was easier and faster to use and attained relatively increased sensitivity and specificity for the cutoff value of the pulmonary hypertension detection compared to the HRCT scoring system-based grading scale.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This prospective study included 30 patients with primary solid malignancies who underwent WB-MRI. The sequences obtained were T1WI, STIR, and T2-Dixon (fat-only and water-only images). Skeletal metastases were evaluated in each sequence. Results were compared between the T1-STIR combination and T2-Dixon fat and water reconstructions. The sensitivity of fat and water reconstructions from a single T2-Dixon in the detection of lytic skeletal metastases was marginally superior to a combination of T1WI and STIR sequences (0–7%). Detection of mixed lesions demonstrated equally high sensitivity in both protocols. Sclerotic metastases detection in WB-MRI showed low sensitivity in both protocols. However, specificity surpassed 95% for all lesion types in both protocols. Overall image quality was favored (in 87–90% of patients) in T2-Dixon images. The overall estimated acquisition timing using T2-Dixon appeared to be approximately half that of the standard T1-STIR combination.

It can save high-risk patients from radiation exposure and hazards of intervention such as general anesthesia and biopsy. To estimate the accuracy of different advanced MRI quantitative parameters in the differentiation between benign and malignant mediastinal lymphadenopathy. This would involve the lesion-to-cord signal intensity ratio (SIR) in the T2-WI and diffusion weighted image (DWI), the lesion-to-chest wall muscle SIR in T2-WI and DWI, and the mean apparent diffusion coefficient (ADC) values.

Naveen","doi":"10.1186/s43055-024-01325-9","DOIUrl":"https://doi.org/10.1186/s43055-024-01325-9","url":null,"abstract":"A tongue abscess is a rare but serious condition marked by a localized accumulation of pus within the tongue’s tissues. Despite the tongue’s frequent exposure to trauma, bites, and foreign objects, it typically resists infections. However, an acute lingual abscess can be life-threatening due to the risk of airway obstruction from tongue swelling. Common symptoms include increasing pain, fever, swelling, immobility, edema, and redness of the tongue. The case report aimed to highlight the unusual clinical presentation and location of a deep-seated abscess in the anterior third of the tongue, as well as the radiographic approach to diagnosing the lesion. A 30-year-old female patient presented with sudden onset tongue pain and swelling persisting for 4–5 days. Clinical examination revealed a solitary diffuse swelling in the anterior two-thirds of the tongue, approximately 3 × 2 cm in size. Diagnostic imaging, including a plain radiograph, ultrasound (USG), and MRI, was conducted. The patient was hospitalized for incision and drainage of the abscess, followed by a 5-day course of intravenous antibiotics. A tongue abscess, though rare, is a serious condition indicated by tongue swelling, pain, fever, dysphagia, and dyspnea. Diagnosis involves physical examinations and imaging studies like ultrasound or MRI. Immediate treatment includes maintaining airway patency, draining the abscess, and administering broad-spectrum antibiotics. Prompt recognition and treatment are essential to prevent severe complications such as airway obstruction and sepsis. Regular follow-up ensures complete resolution and prevents recurrence.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
