The imaging appearances of various pericardial disorders

AbstractThe pericardium could be involved in a variety of clinical disorders. The imaging findings are not specific for an individual pathology in most of the cases; however, patient ’s clinical history may guide radiologist to a definitive diagnosis. Congenital absence of the pericardium could be recognized with the imaging appearance of interposed lung tissue between the main pulmonary artery and aorta. Pericardial effusion is a non-specific condition that may occur due to i nflammatory, infectious, and neoplastic disorders. Cardiac tamponade may occur in case of massive or rapid accumulation of fluid in the pericardial sac. Pericardial calcification is a common and easily identified entity on a computed tomography (CT) scan. Presence of calcification and/or fibrosis ma y result in pericardial constriction. Nevertheless, the pulsation of an adjacent coronary artery may prevent calcification formation in a focal area and consequently may result in pericardial diverticulum containing epicardial fat and coronary artery. The imaging findings encountered in patients wit h pericardial hydatid disease and Erdheim-Chester disease may mimic those of pericardial neoplasia. Pericardial adhesions and pedicled fat flaps may cause confusion on a CT scan in the post-surgical period following cardiac surgery. Pericardial fat necrosis can be diagnosed by CT in patients with ch est pain. The radiologists should be familiar with the medical devices placed in pericardial space for certai...

ConclusionPrevention of hydatid disease is the most effective way to control the disease, the cyst may reach a very large size and be asymptomatic. Intraperitoneal rupture may occur as a result of blunt abdominal trauma which could be trivial.

This study aimed to analyze the demographic, clinical, diagnostic and therapeutic data of CE patients across all provinces in Iran. In this cross-sectional study, the mentioned data were routinely collected by provincial medical universities during the time from March 2016 to March 2017. The provincial population census was used to calculate the prevalence of CE per 1,000,000 populations for all provinces.T test and Chi squared test were used to compare variables between genders. Statistical analysis was done at 95% significant level using STATA 14 software. The overall prevalence of CE was 6.8 cases per 1,000,000 populati...

ConclusionThe presence of any cystic lesion in any organ in a patient from an endemic area for hydatid disease should raise the suspicion to this possibility. Treatment options should be chosen by a multidisciplinary team; certain group of patients may benefit from medical treatment. Surgery is still the main treatment modality.

Rationale: A characteristic metabolic finding of hepatic alveolar echinococcosis (HAE) on positron emission tomography/computed tomography (PET/CT) correlates with morphologic features on CT and magnetic resonance imaging (MRI). Patient concerns: A young man from an endemic area was admitted to our hospital due to right upper quadrant pain for 2 months. Diagnosis: CT and MRI revealed a heterogeneous mass with calcification, consisting of central necrosis and peripheral solid inflammatory tissues. Accordingly, FDG PET/CT demonstrated a characteristic metabolic finding of doughnut sign. Combining the above characteri...

Authors: Nosrati A, Soleymani E, Davoodi L Abstract Echinococcus granulosus has been described as the common etiology of hydatid cysts in many parts of the world. A 54-yr-old female with lower abdominal pain referred to Gynecology Ward of Sari Imam Khomeini Hospital, Iran in 2016. Sonography was carried out and cysts in ovaries and liver were observed. The cysts of liver seemed to be hydatidosis but physicians were suspected about ovarian cystic mass. Anti-Echinococcus antibodies (ELISA) screen was positive. The operation was done on her and treatment by albendazole started one week before surgery and continued aft...

Tunisia is an endemic area for lung hydatidosis. The clinical presentation depends on whether the cyst is intact or ruptured. We aimed to compare the clinical and therapeutic features between intact and ruptured hydatid cysts of the lung.Between January 2014 and December 2017, 152 patients were managed for a lung hydatid disease in the thoracic surgery department of Abderrahmen Mami hospital. A retrospective analysis was performed and the patients were divided into two groups based on whether the hydatid cyst was intact (group 1, n=43) or ruptured (group 2, n=109).The median age was 36 years old[5-84years]. Reported compli...

ConclusionsClinical presentation and radiologic imaging findings of disseminated alveolar echinococcosis can mimic metastatic malignancy, and diagnosis can be challenging in atypically advanced cases. As the incidence of human alveolar echinococcosis appears to be increasing in Europe and Switzerland, physicians should be aware of alveolar echinococcosis, its epidemiology, and its clinical features.

CONCLUSION: The prevalence of human hydatidosis, as a most important neglected disease, should be considered by health policy-makers in public health domain. In addition, educational programs to better recognition of the disease symptoms, and to identify the infection sources are needed in high risk group of population.

Authors: Moreno Serrano A, García Díaz JJ, Ferrer Márquez M, Moreno Marín P, Fabiano P Abstract A 31-year-old Moroccan male patient from a rural area, with no remarkable history, presents at the emergency room for breathlessness and abdominal pain of one week standing. A thorough physical exam and chest-abdominal CT scan were performed, which revealed three large hydatid cysts in the liver, the bigger one in segment VI, as well as massive peritoneal hydatid disease. He was admitted to Surgery and put on fluid therapy, analgesia, and drug therapy including albendazole and praziquantel. On...

Authors: Adwani S, Karkhanis VS, Joshi JM Abstract Diagnosis of lung hydatidosis becomes difficult with unusual radiographic findings especially with rupture of hydatid cyst. Here we present the case of a patient who presented with hydatid cyst with endobronchial rupture. A 40-year-old woman presented with a 3-year history of cough with mucoid expectoration, breathlessness on exertion, intermittent fever and left-sided chest pain. Chest radiograph and computed tomography of chest showed a mass obstructing the left main bronchus and post-obstructive cavity formation. Fluorodeoxyglucose positron emission tomography (...
