Hydatid Disease Involving Some Rare Locations in the Body: a Pictorial Essay

Hydatid disease (HD) is an endemic illness in many countries, and it poses an important public health problem that's influenced by peoples' socioeconomic status and migration that spreads this disease. Although rare, it may occur in any organ or tissue. The most common site is the liver (59-75%), followed in frequency by lung (27%), kidney (3%), bone (1-4%) and brain (1-2%). Other sites such as the heart, spleen, pancreas and muscles are very rarely affected. Unusual sites for this disease can cause diagnostic problems. This pictorial essay illustrates various radiological findings of HD in the liver, spleen, kidney, pancreas, peritoneal cavity, omentum, adrenal, ovary, lung, mediastinum and retroperitoneum. Familiarity with the imaging findings of HD may be helpful in making an accurate diagnosis and preventing potential complications

Carotid CT angiography: comparison of image quality for left versus right arm injections

WOS: 000294197400002PubMed ID: 20698005PURPOSE To evaluate the differences in image quality of carotid computed tomographic angiography (CTA) of patients injected with contrast material in their right arms versus patients injected with contrast material in their left arms. MATERIALS AND METHODS Patients who had cerebrovascular accidents and subsequently underwent CTA were included in the study. Contrast material was injected into the right arms of 44 patients and into the left arms of 46 patients. Source images of a total of 90 CTAs were retrospectively evaluated for perivenous streak artifacts and contrast material reflux into the veins of the neck and upper thorax. After adjusting for differences in gender, the relationship between the injection site and the intensity of perivenous streak artifacts and venous reflux was determined. RESULTS Perivenous streak artifacts and venous reflux were demonstrated in patients who underwent either right or left arm injections. However, the intensity of perivenous streak artifacts was stronger in patients who were injected with contrast material in the left arm. Venous reflux into the neck and upper thorax veins was also more severe and more frequent with left arm injections. A decreased retrosternal distance facilitated reversed flow into the veins when the left arm injection was used. CONCLUSION Perivenous beam hardening streak artifacts and venous reflux could not be prevented with right or left arm injections. However, patients who were injected with contrast material in their right arms showed fewer artifacts, thus allowing for better quality images on CTA

Mammographic features of the sternalis muscle

WOS: 000285038500005PubMed ID: 20700868PURPOSE To evaluate the mammographic findings of the sternalis muscle and discuss appropriate diagnostic approaches. MATERIALS AND METHODS Ten years of records from our mammography unit were retrospectively examined for the presence of the sternalis muscle. This variant was seen in 10 women out of the 52,930 examined, and the mammograms of these patients were reevaluated. The size, shape and contours of the muscle were reviewed on the craniocaudal (CC) and mediolateral oblique (MLO) views. Yearly mammograms were assessed to evaluate follow-up changes. Extra examinations were reviewed, including ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI). RESULTS The prevalence of the sternalis muscle was 0.018%. Its contours were well-defined, irregular or spiculated, and the diameter ranged from 3-4 mm to 15 mm. The shape of the muscle varied from slightly bulging to round or triangular. The muscle was detected on MLO projections in three patients as an inferior soft tissue density at the posterior edge of the breast, continuous with the pectoralis muscle. Distinct pulling of the breast led to variations in the appearance of the muscle on yearly mammograms. US examinations were normal in all patients. CT and MRI showed the muscle clearly. CONCLUSION The appearance of the sternalis muscle may vary on CC views. It may also be detected on MLO projections. The ability to visualize the muscle depends on proper positioning. Knowledge of its detectability on mammograms will prevent the misdiagnosis of a mass and prevent further unnecessary investigations

An interrupted right pulmonary artery with stenotic right pulmonary veins

WOS: 000352520800033Interrupted pulmonary artery is a very rare congenital abnormality. It may be detected at an early age or in adulthood. It may be associated with congenital cardiovascular defects. However, it is usually isolated and detected incidentally in adults. In this article, we present clinical and radiological findings of a 50-year-old female patient with interrupted right pulmonary artery and stenosis of the inferior pulmonary veins in the affected lung, in light of the literature review
