RESUMO

In modern era, with tremendous competition, long working hours and more demanding workstyle, nearly every profession is associated with some or the other health hazards. These may develop and progress rapidly or in a gradual way but ultimately add up unwanted morbidities and in long run affects the production and work output. Unfortunately, doctors and other health professionals who look after the health of society, are not the exceptions to this rule and depending upon their specialty, they have to face some or the other health issues. This article highlights some important though underestimated health issues among radiologists and some remedies. It aims to sensitize radiologists about such health issues so that they can take timely remedial measures before it is really late.

RESUMO

The small airways, once regarded as the silent zone in the air conducting system of the lungs are now known to be one of the initial sites of involvement in diseases like asthma and Chronic Obstructive Pulmonary Disease (COPD). Identification of the involvement of distal airways in these diseases is often difficult to assess, clinically as well as by conventional pulmonary function tests and therefore, usually remains undiscovered in early stages. Early recognition of their involvement in asthma and COPD and timely management may reduce long term morbidity in these conditions. This article aims to highlight the relatively lesser recognized facts about small airways involvement in asthma and COPD and role of imaging and newer modalities for detection.

RESUMO

Aspergillus is a large genus of saprophytic fungi which are present everywhere in the environment. However, in persons with underlying weakened immune response this innocent bystander can cause fatal illness if timely diagnosis and management is not done. Chest infection is the most common infection caused by Aspergillus in human beings. Radiological investigations particularly Computed Tomography (CT) provides the easiest, rapid and decision making information where tissue diagnosis and culture may be difficult and time-consuming. This article explores the crucial role of CT and offers a bird's eye view of all the radiological patterns encountered in pulmonary aspergillosis viewed in the context of the immune derangement associated with it.

RESUMO

OBJECTIVE: To evaluate the ability of Multi-Detector Computed Tomography in preoperative evaluation of locally aggressive and malignant bone tumours in correlation with histopathological findings. MATERIALS AND METHODS: Twenty patients suspected of malignant bone tumours on the basis of their clinical profile were selected. Following a plain radiograph evaluation, all of them were subjected to CT scan examination. Multi Planar Reconstruction (MPR) was done in sagittal and coronal planes and also three-dimensional Volume Rendering (VR) and Maximum Intensity Projection (MIP) images were obtained. RESULTS: Of the 20 patients, 18 underwent surgery, and their histopathological findings were compared and correlated with MDCT findings. MDCT was 92.8% sensitive and 100% specific in determining the vascularity of the tumour and also can detect displacement/ encasement/ involvement of adjacent vessels. It has a sensitivity and specificity of 100% in determining cortical break, calcification and periosteal reaction. However, it is less sensitive in detecting joint involvement. Post contrast enhancement gives details of the extent of the soft tissue component. CONCLUSION: Although MRI is a preferred modality in preoperative evaluation of bone tumours, CT may be used an alternative in case of non-availability of MRI, which has faster acquisition time and better resolution. Using three dimensional MPR imaging, the location and extent of the tumour can be studied. It is also useful in determining cortical discontinuity, periosteal reaction, and calcification. By virtue of MIP and VR imaging, vascularity of the tumour and its relationship with the adjacent vasculature can be established. However, it is inferior to MRI in soft tissue characterization and has poor sensitivity in detecting marrow and joint involvement.

RESUMO

Ewing's sarcoma is a common malignant bone tumour presenting in children and young adults. Rarely extra- skeletal soft tissues and visceral organs can also be the site of origin of Ewing's sarcoma. Primary pulmonary Ewing's sarcoma is an extremely rare malignancy which occurs in the paediatric population. We report an unusual case of primary pulmonary Ewing's sarcoma in a nine year old girl who presented with features of superior vena cava syndrome in the emergency department. The diagnosis was confirmed pathologically both by light microscopy and immunohistochemistry. The patient was put on chemotherapy and surgery was planned but the patient expired within three days of starting chemotherapy.

RESUMO

BACKGROUND: Pulmonary infections remain a leading cause of morbidity and mortality and one of the most frequent causes of hospital admission in HIV infected people worldwide. HRCT may be useful in the evaluation of patients with suspected pulmonary disease. The aim of given study was to determine the High Resolution Computed Tomography spectrum of lung parenchymal and interstitial imaging findings in HIV infected patients presented with chest symptoms. MATERIALS AND METHODS: This study was conducted in a tertiary health care centre, New Delhi, India. The study consisted of 45 patients. A thorough clinical history of all the HIV positive patients presenting with suspicion of pulmonary disease was taken. General physical and respiratory system examination of all patients was done. HRCT scans of the chest were done in all the cases taken in the study. RESULTS: Maximum number of patients was in age group 31-40 years (24 cases). Out of 45 patients included in our study, 32 (71%) were male and 13 (29%) were female. In our series of 45 patients, 62.2% of patients were diagnosed as having pulmonary tuberculosis, followed by bacterial infection in 20% cases and Pneumocystis jiroveci pneumonia (PJP) in 8.9% patients, while 8.9% of the study did not reveal any significant abnormality. Maximum number (22/28) of patients with pulmonary tuberculosis were indentified to have nodular opacities. The most common HRCT finding in bacterial infection was lobar consolidation. The most common HRCT finding in patients with PCP was diffuse ground glass opacities in mosaic pattern of distribution. CONCLUSION: HRCT is a highly sensitive tool for detecting lung parenchymal and interstitial lesions and allows better characterization of the lesions. HRCT findings should always be correlated with clinical findings, CD4 counts and other available investigations before arriving at a diagnosis or differential diagnosis.

RESUMO

Juvenile Dermatomyositis (JDM) is a rare autoimmune inflammatory disease of muscles affecting children and adolescents with soft tissue calcification and varying systemic involvement. Though diagnosis is primarily by clinical, biochemical and histopathological tests, Imaging has unique significance from characterizing the calcinosis, detecting early changes in muscle in active phase of the disease, diagnosing potential complications,rule out other important differentials, guide biopsies ,and assessing the progress on follow up. Four distinct patterns of calcinosis have been described in relation to dermatomyositis which need to be differentiated from other aetiologies of soft tissue calcification and myopathies.
