A rare phenotype of breast hydatid cyst causing misdiagnosis and unnecessary intervention: a case report.

Hydatid cyst (cystic echinococcosis) is a chronic parasitic infection by the larval stage of the cestode that is called resulting in the development of cystic lesions in animals and humans. In this report, we describe a rare phenotype of hydatid cyst in the breast of a 23-year-old female presented with breast mass in the left upper outer quadrant for 3 months with palpable left axillary lymph nodes. Both US and mammography provided a picture of complex suspicious cystosolid lesion with amorphous micro-calcification (BIRAD-4A).

Frequent clinical and radiological manifestations of the Novel SARS-CoV-2: A review article.

Coronavirus disease 2019 (COVID-19) is a highly infectious disease caused by the novel "severe acute respiratory syndrome coronavirus-2" (SARS-CoV-2) and is rapidly spreading worldwide. This review is designed to highlight the most common clinical features and computed tomography (CT) signs of patients with COVID-19 and to elaborate the most significant signs indicative of COVID-19 diagnosis. This review involved five original articles with both clinical and radiological features of COVID-19 published during Jan and Mar 2020.

Multivalvular destruction as the primary presentation of aggressive infective endocarditis with subaortic valve membrane.

Multivalvular destruction may be a clinical manifestation of infective endocarditis (IE), which is a devastating infection of the heart either alone or superimposed with congenital subaortic membrane as in this case report. Here, we report a case of multivavular destruction with severe vegetation presented as a manifestation of infective endocarditis (IE) in a neglected case of 18-year-old male with previous rheumatic heart disease. Transesophageal echocardiography is an important imaging modality for diagnosis of superimposed aortic and heart lesions.

Diagnosis and risk stratification of coronary artery disease in Yemeni patients using treadmill test.

Background: Coronary artery disease (CAD) is a common medical problem that remains a great cause of morbidity and mortality. Based on clinical manifestation, CAD span from chronic stable angina to acute coronary syndrome (ACS), which encompasses (1) unstable angina (UA), (2) non-ST-elevation myocardial infarction (NSTEMI), and (3) ST-elevation myocardial infarction (STEMI).

Objective: This study was conducted to describe the risk stratification and prognosis of CAD in Yemeni patients undergoing an exercise stress test.

Gender and side distribution of urinary calculi using ultrasound imaging.

Introduction: Urinary calculi constitute a significant medical problem worldwide. Due to lack of previous studies on gender and side distribution of urinary calculi, the current study was conducted.

Patients And Methods: This retrospective study involved 590 urinary calculi from the electronic reports of 266 patients.

Descriptive study of knee lesions using magnetic resonance imaging and correlation between medical imaging diagnosis and suspected clinical diagnosis.

Objective: This study aimed to assess the meniscus and cruciate ligament lesions of the knee using magnetic resonance imaging (MRI) and to investigate the correlation between clinical and MRI diagnoses.

Patients And Methods: Herein, we reviewed the electronic medical records of 240 patients who underwent knee MRI. The images were evaluated and then the clinical and MRI diagnoses were compared.

Histopathological analysis of sinonasal lesions associated with chronic rhinosinusitis and comparison with computed tomography diagnoses.

Background &objective: Chronic rhino sinusitis (CRS) is an inflammatory condition of the paranasal sinuses and the nasal passage lasting more than three months either with or without sinonasal polyps. This study aimed to report the common sinonasal lesions associated with CRS according to the histopathology results, to compare between clinical and histopathological diagnoses, and to compare between radiological and histopathological diagnoses of the sinonasal lesions.

Methods: A retrospective study of the electronic records of 82 patients diagnosed with CRS with nasal polyps.

Doppler sonographic assessment of carotid arteries in Sudanese stroke patients.

Background: Hypertension, diabetes, and smoking were considered to be associated with several public health problems.

Objective: the study aims to explore the hemodynamic of carotid arteries in association with hypertension, diabetes, and smoking in Sudanese stroke patients.

Materials And Methods: In a quantitative descriptive study, fifty patients with stroke were scanned by B-mode and Doppler sonography.
