hydatid cyst (hc) is a parasitic disease that may involve many organs, especially the lung and the liver. pulmonary artery location of the hydatid cyst is extremely rare, but it may cause life-threatening complications. we report a case of a hydatid cyst that completely filled the left main pulmonary artery and its distal part without cardiac involvement. thoracic computed tomography showed fil...
Objective: Myofascial pain syndrome is a common disorder with a prevalence of up to 85%. It is characterized by the presence of trigger points, which all people are commonly encountered at least once throughout their lifespan. Different physical therapy and medical treatments have used to manage myofascial pain syndrome. Intramuscular electrical stimulation intervention is a relatively new trea...
colloid carcinoma, also called mucinous carcinoma, is classified as a histologic variant of adenocarcinoma. because the colloid carcinoma of the biliary tree is exceedingly rare, the imaging characteristics and the clinical features of colloid carcinoma remain relatively unknown. we report a case of colloid carcinoma of the common bile duct and its accompanied metastatic lymphadenopathies with ...
Objective: Each imaging technique has a special application and usage, and should be used in the right situation. Physicians choose the type of imaging technique by considering the type of tissue and the benefits and disadvantages of the imaging method as well as its financial burden on the patient. The aim of this study was to estimate the cost of imaging tests performed in the emergency depar...
Interoduction: Ultrasound images have often low contrast due to small differences in acoustic impedance between different tissues. Air or gas microbubbles that surrounded by membrane are most of the contrast agents in ultrasound imaging. Problems such as instability in sound pressure and inability in penetrating from the blood vessel into body tissues limited the use of microbubbles into the in...
fundal gallbladder abnormalities result from broad spectrum of pathologic that most of them have no pathological significance and normally causes no symptoms. conversely, early incidental detection of malignant lesions is important because symptomatic lesions are often incurable. so use proper imaging to differentiate between them is important. although ultrasound has been the choice screen met...
Despite increasing detection rates of various forms of extrapulmonary tuberculosis (TB), thyroid involvement with tubercle bacilli is rarely encountered and its imaging features have been reported in less than a handful of cases. Herein, we present the clinical, pathologic and imaging (ultrasound and CT scan) features of TB involvement of the thyroid gland in a 65-year-old woman who presented w...
Parathyroid adenomas, or hyperplasia may be present in patients with hypercalcemia. Treatment Is by surgical excision, but about 10% of the lesions may be In ectopic locations. Pre-operative localization of the lesions with non-lvasive imaging, using radionuclides, ultrasound, CT, or MR], may simplify surgery, and reduce patient morbidity. However, the reports of the accuracy of the curre...
rhabdomyosarcoma is a common primary childhood malignancy that rarely metastasizes to the breast. we report a patient with a primary sinonasal rhabdomyosarcoma metastasizing to the breast, with no distant spread. we describe the imaging appearance of rhabdomyosarcoma on magnetic resonance imaging (mri), particularly on diffusion-weighted imaging (dwi) and apparent diffusion coefficient (adc) se...
giant uterine leiomyomas are extremely rare neoplasms and are challenging both diagnostically and therapeutically. a 49-year-old premenopausal female presented at our department complaining of abdominal pain and distention for several years. ultrasound (us), color doppler us, abdominal computed tomography imaging after administration of contrast material, and abdominal magnetic resonance imagin...
