MATERIAL AND METHODS A prospective study of 100 patients in all age groups with skin lesions based on clinical data who presented to Bowring and Lady Curzon Hospital, Victoria Hospital and Vani Vilas hospital attached to Bangalore Medical College and Research Institute, Bengaluru, from November 2014 to May 2015 were subjected to HRUS examination. Study design: It was a Cross sectional study. Totally 100 patients were studied from November 2014 to May 2016. Inclusion criteria: All clinically suspected patients with superficial skin lesions. Exclusion Criteria: Patients with trauma. After taking Informed consent, all patients included A B S T R A C T Introduction: In the evaluation of cutaneous lesions, High Resolution Ultrasonography (HRUS) with color Doppler is useful as a safe, noninvasive, economical, and repeatable diagnostic procedure that can reduce and replace invasive procedures like fine needle aspirations and biopsies. Analysis of the skin surface allows the investigation of tumor and inflammatory diseases, the measurement of skin thickness. The objective of this study was to evaluate the role of HRUS in cutaneous lesions with histopathological correlation wherever possible. Material and Methods: A prospective study of 100 patients with skin lesions based on clinical data were subjected to HRUS examination. Collected data was analysed by descriptive statistics. Results: The study comprised of a total of 100 patients, out of which 75 were non-neoplastic and 25 were neoplastic lesions. The non-neoplastic lesions included Psoriasis, edema, lymph nodes and vascular malformations. The neoplastic lesions included 16 benign and 9 malignant cases. The observed HRUS and Doppler characteristics of these lesions are discussed in detail. Conclusion: HRUS is non-invasive, affordable, easily available, rapid imaging technology. It can be used to localize the skin lesion, generate differential diagnosis and to follow up known lesion.

Introduction: Dengue fever is one of the most common acute vector-borne viral illnesses affecting mankind. Despite an abundance of case material worldwide , cross-sectional lungimaging data in patients with dengue is scarce. The aim of the study was to detect and evaluate the thoracic CT findings in dengue fever. Material and methods: Chest CT findings of 30 patients with dengue fever in a 6 month period from July to December 2017 were studied. Results: The commonest chest CT findings were pleural effusion (n=20), atelectasis (n=14), ground-glass opacification (n=6), patchy consolidation (n=4), air space nodules (n=3), interstitial thickening (n=3) and pericardial effusion (n=1). Conclusion: CT thorax is a good modality for evaluation of dengue patients with respiratory complaints. Frequently detected findings on chest CT included pleural effusion, atelectasis and ground-glass opacification.

BACKGROUNDDengue fever is considered to be the most common acute vector-borne viral infection affecting man. The WHO estimates more than 50 million cases spread over more than 100 countries occur worldwide every year. Despite this abundance of case material, limited articles with regard to the CT findings in dengue fever are noted in the published literature.The aim of the study is to characterise and evaluate the CT findings in Dengue fever in patients with severe disease. MATERIALS AND METHODSAbdomen and chest CT findings of 22 patients with severe DHF in a 3-month period from June to August 2017 were evaluated in a hospital setting in a semiurban location in Kerala, India. Those patients who underwent both abdomen as well as chest CT exams as part of their workup were categorised in WHO DHF grade I-IV. RESULTSThe commonest chest CT findings were pleural effusion (n=19), atelectasis (n=16), ground-glass opacification (n=9), patchy consolidation (n=7) thickening of the peribronchovascular interstitium (n=3) and pericardial effusion (n=1). The commonest abdomen CT findings were ascites (n=16), gallbladder wall thickening (n=14), hepatomegaly (n=10), splenomegaly (n=8), pancreatitis/bulky oedematous pancreas (n=3), perinephric haematoma (n=1) and appendicitis (n=1). CONCLUSIONThe study documents the common findings on chest and abdomen CT. The most frequently detected findings on chest CT were pleural effusion, atelectasis and ground-glass opacification, while the most commonly occurring abdomen CT findings were ascites, gallbladder wall thickening, hepatomegaly and splenomegaly.
