Cystic echinococcosis (CE) or hydatidosis (hydatid cysts) is an infection with a wide spectrum of manifestations, from symptomatic infection to fatal disease. Ultrasound (US) allows screening, diagnosis, differential diagnosis, treatment guidance and follow-up of CE under many circumstances. Hydatid cysts are predominantly observed in the liver. Herewith we present a review to demonstrate established and innovative imaging features of CE of the hepatobiliary tract.

Cystic echinococcosis (CE) or hydatidosis (hydatid cysts), is an infection with a wide spectrum of manifestations, from asymptomatic infection to fatal disease. Ultrasound (US) allows screening, diagnosis, differential diagnosis, treatment guidance and follow-up of CE under many circumstances. Hydatid cysts are predominantly observed in the liver but many other organs can be involved. As part of a series of publications, herewith we present a review describing the characteristic imaging features of the broad variety of organs which can be involved.

RESUMOIntrodução: A Arterite de Takayasu (AT) consiste em uma vasculopatia de origem indefinida, sendo de caráter crônico, que afeta a aorta e seus ramos principais. Em gestantes é uma condição complexa, em que o tratamento clínico é realizado com restrições. A utilização de corticoides tem sido favorável no controle inflamatório, principalmente naqueles casos em que antes da gravidez se fazia uso de imunossupressores. Casuística: Foi relatado um caso de uma gestante portadora de AT, através da análise de prontuário e de exames complementares, sendo realizado o pré-natal pelas equipes de Obstetrícia e Reumatologia, onde foi realizado tratamento clínico com corticoides, mostrando uma evolução satisfatória, ocorrendo apenas uma hospitalização que foi seguida de uma cesárea na trigésima sexta semana de gravidez, com recém nato saudável de 3.810g. Discussão: A AT pode estar associada a várias etiologias, sendo a gênese pouco conhecida. O diagnóstico na maioria das vezes é demorado, pela dificuldade da suspeita clínica, além de demandar o uso de técnicas de imagem mais sofisticadas. A gestação associada é fenômeno raro, já que as portadoras são orientadas a evitarem a gravidez. O controle clínico permitiu uma gestação sem grandes complicações e serviu como meio para levar a gestação até praticamente o fim do terceiro trimestre. Conclusão: Deve-se ressaltar o papel do acompanhamento clínico, especialmente com esta pan-arterite, mostrando os medicamentos que podem ser utilizados nesse grupo, especialmente quando se usava imunossupressores antes da gravidez. Palavras chave: Arterite de Takayasu, Gravidez, Vasculite. ABSTRACT:Introduction: Takayasu's arteritis (TA) consists of a vascular disease of unknown origin and chronic nature, which affects the aorta and its main branches. In pregnant women it is a complex condition, in which the clinical treatment is performed with restrictions. The use of corticosteroids has been favorable to control inflammation, especially in those cases when immunosuppressant had been used before pregnancy. Case Report: A case of a pregnant patient with TA has been reported through the analysis of medical records and laboratory tests. The Obstetrics and Rheumatology staff performed the prenatal care, and clinical treatment with corticosteroids was done showing a satisfactory outcome. There was only one hospitalization of the patient, which was followed by a cesarean in the thirty sixth week of pregnancy.  The newborn was a healthy one, weighing 3.810g. Discussion: TA may be associated with several etiologies, and the genesis is little known. The diagnosis most often takes time due to the difficulty of clinical suspicion, and requires the use of more sophisticated imaging techniques. The pregnancy is rare phenomenon, since the carriers are advised to avoid pregnancy. The clinical management allowed a pregnancy without major complications and served as a means to carry the pregnancy to almost the end of the third quarter. Conclusion: The role of the clinical follow-up should be noticed especially with this pan-arteritis, showing the drugs that can be used in this group, especially when there is use of immunosuppressive drugs before pregnancy. Keywords: Takayasu Arteritis, Pregnancy, Vasculitis.

Invasive cardiac aspergillosis is a rare, potentially fatal disease which poses a significant diagnostic challenge. Combination of clinical details, imaging features, fungal markers, serology and fungal isolation with demonstration of invasion is usually necessary to establish the diagnosis. High index of suspicion is the key for early diagnosis with potential role of cardiac MRI in its early detection, delineation of extent of involvement and guidance to the appropriate site for tissue sampling, thereby allowing for improved prognosis with early institution of appropriate therapy.

Various imaging techniques are used in the staging and follow-up of head and neck cancer and evaluating patients presenting with a neck mass. The workhorses in imaging the neck are ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) with positron emission tomography CT (PET-CT) increasingly being requested. Plain radiographs, contrast studies, video fluoroscopy, angiography, and cone beam CT have limited but important roles. This chapter discusses the role of some of these modalities.

Cardiac imaging techniques have an important role in the follow-up of patients undergoing cardiac resynchronization therapy (CRT) as they provide objective evidence of changes in cardiac dimensions and function. The role of echocardiography is well established in the assessment of left ventricular reverse remodelling and the evaluation of secondary (functional) mitral regurgitation. Additionally, echocardiography might be used for optimizing the programming of atrio-ventricular (AV) and inter-ventricular (VV) delays of current CRT devices. Acute benefits from this optimization have been demonstrated, but longer follow-up studies have failed to show a clear benefit of optimized CRT on top of simultaneous biventricular pacing on the outcome of patients with CRT. This chapter reviews the role of imaging in assessing follow-up and outcome of patients undergoing CRT, as well as the rationale, the methods used, and the clinical impact of optimization of the programming of CRT devices.

Polymyalgia rheumatica (PMR) is a chronic, inflammatory disorder of unknown cause clinically characterized by pain and prolonged morning stiffness affecting the shoulders and often the pelvic girdle and neck. Imaging has substantially contributed to defining PMR as a disease mainly involving extra-articular structures. This review article analyses the role of the different imaging techniques in the diagnosis and follow-up of patients with PMR with particular emphasis on the role of ultrasound, PET/CT and MRI.

A wide spectrum of nowadays availible radiological and imaging methods in the diagnostic evaluation of patients with colorectal cancer enabled not only the improvement of primary colorectal malignancy detection, precise staging, regional involvement and metastatic spread assessment, but also the posttherapeutical estimation and follow- up. Having in mind that the exact diagnostic assessment of colorectal carcinoma by use of different imaging modalities still raises a lots of contradictories, in this report we have tried to present the possibilities of newer imaging techniques in the diagnostic evaluation of the patients with colorectal cancer.
