To highlight the role of ultrasonography and MRCP as preliminary investigation in patients with obstructive jaundice. Materials and Methods: Thirty patients with complaints of jaundice and clinico-pathological appearance of obstructive jaundice were included in the study. The patients had undergone sonography of abdomen in radiology department and then MRCP study was conducted. Data of patients matching inclusion criteria were recorded after getting informed consent. Result: Of 30 patients, 17 (56.66%) were females and 13 (43.33%) were males. Most common age group of patients was 51-60 years (23.3%) followed by 61-70 years (16.6%). Jaundice was the most frequent symptom (96%) followed by abdominal pain (86.66%). Common bile duct (CBD) was most commonly involved in 50% of cases followed by confluence of right and left hepatic duct and pancreas in 13.33%. Most common obstructive lesions in this study were congenital anomalies of CBD (choledochal cyst) in 30% cases followed by stone in CBD +/-CHD with or without stricture in 19.99% cases. In this study, of 30 cases, 16 (53.33%) were benign lesions and 14 (46.66%) were malignant. Among benign lesions, choledochal cyst was the most common (9/16; 56.25%), especially more among females. However, among malignant lesions, hilar cholangiocarcinoma was most common (5/14), especially among females. USG (30/30) was found to be equally good as MRCP (30/30) in detecting the presence and level of obstruction. In detecting the extent of obstruction, USG could not localize the distal extent of the lesion involving distal CBD (6/30) due to poor patient factors (obesity) and bowel gases. In assessing the cause of obstruction, MRCP (30/30) scored over USG. Conclusion: USG is a cost-effective, noninvasive, and nonionizing easily available preliminary investigation in the evaluation of obstructive jaundice but MRCP scores over USG for evaluation of small hepatic metastasis in the presence of pancreaticobiliary malignancies that may be missed with USG.
Background: The diseases affecting the mediastinum very considerably, ranging from tumor, cysts, vascular anomalies, lymph node masses, mediastinitis, mediastinal fibrosis, to pneumomediastinum. For accurate diagnosis various imaging modalities are now available, which helps in in-depth study of various masses. Objective: To study imaging appearance, distribution, and other features of various mediastinal mass lesions. Also to compare the various modality of imaging findings with each other and with histopathologic diagnosis. Materials and Methods: This is a prospective study carried out in suspected cases of mediastinal masses. All participants were underwent various imaging procedures such as chest radiographs, barium swallowing study, computerized tomography (CT) scan, and magnetic resonance imaging. Result: Of total 50 participants, 23 had benign, 22 had malignant, and 5 had vascular lesions. The most common site of mediastinal mass was anterior mediastinum (25), in which the most common type of masses was of thymic origin (9). Masses of posterior mediastinum (18) were other common types, with esophageal carcinoma (7) being the most common lesion. In the CT scan, of 42 lesions, 29 showed solid, 6 showed cystic, and 7 showed mixed consistencies, whereas 13 showed calcifications. Conclusion: The most common type of mass in anterior mediastinum is thymic mass. CT scan and magnetic resonance imaging help the clinicians and radiologists in identifying the precise location, extent, and characterization of these masses.
