Aim: To characterize incidentally detected adrenal masses by CT attenuation values and 15 minutes wash out characteristics at contrast-enhanced CT. Method : Prospective observational study from March 2012-2013 was done, with all the abdominal scan evaluated for adrenal masses. Departmental protocol was followed with 15 minutes delayed scan added. CT attenuation values at different phases were used to calculate absolute percentage washout (APW) and relative percentage washout (RPW). The masses with attenuation value ⩽10HU on unenhanced scans were diagnosed as lipid rich adenomas and masses with attenuation values >10 on plain scan with APW of >60% and RPW>40% were diagnosed as lipid poor adenomas; rest being non-adenomas, metastasis if there was known malignancy. The masses were evaluated in terms of their sizes, site of involment, stastical significance (p<0.05) in attenuation values at different phases and washout studies. Results: 96 lesions were detected in 84 patients from March 2012-2013. M:F ratios of 1.7:1, mean age being 46 years. Lipid poor adenomas (LPA) were the commonest mass followed by metastasis. 64% of patients with malignancy had adrenal metastasis while 36% had adenomas. There was no significant difference in size(p=0.23) between LPA and non-adenomas (NA) whereas statistical difference was noted in mean attenuation values on unenhanced, delayed, wash-in and wash-out values(p <0.05). There was no significant difference on enhanced scan (p=0.95), but absolute percentage washout (APW) and relative percentage washout (RPW) was statistically significant between LPA and NA (p<0.05). Conclusion: CT attenuation values, absolute and relative percentage washout values characterize the adrenal masses. [ABSTRACT FROM AUTHOR]

Aim: The aim of our study was to analyze the role of Multidetector computed Tomography (MDCT) in the classification and management of high energy blunt abdominal trauma. Material And Method: A Prospective study of 140 patients of all age groups was conducted from October 2010 to October 2012. Rectal and IV contrast were used. Angiography was performed in cases of suspected vascular trauma. Three dimensional reconstructions were done. CT findings were correlated and confirmed by either operative findings or follow-up CT. Result: 140 cases of blunt abdominal trauma were included in this study. Abdominal USG (Ultrasound) and MDCT were performed. Abdominal injuries were more common in males seen in 119 cases (89%). Spleen was the most common organ to be injured, affected in 40 patients (23%). Liver injury was seen in 36 cases, renal involvement in 30 cases, bowel in 20 cases, urinary bladder in 7 cases, a pancreatic injury in 3 cases and retro peritoneum involvement in 2 cases. Out of 140 patients 135 had free intraperitoneal fluid. USG findings and MDCT findings were compared with per operative findings. Patients managed conservatively were compared with repeat follow up CT findings. USG showed a sensitivity of 55 % and specificity of 75 % in solid organs injury and sensitivity of 95 % and specificity of 99 % in free fluid detection. MDCT showed a sensitivity of 97 % and specificity of 98 % in solid organs injury and 100%in hemoperitoneum. Conclusion: MDCT is the modality of choice to evaluate abdominal injury when there is doubt in clinical and USG findings, and to offer patient conservative management. [ABSTRACT FROM AUTHOR]

Aim: Adenocarcinoma is the commonest malignant mass whereas pseudocyst is the commonest benign mass in the pancreas. However our aim is to highlight multidetector computed tomographic (MDCT) features of uncommon masses so as to diagnose them correctly. Material and Methods-20 patients were studied during July 2011 to December 2012. Plain and intravenous contrast scan with arterial and portal venous phases were obtained. Masses were classified as solid or cystic and diagnosis was confirmed by correlating with clinical findings, FNAC or postoperatively. Results-M: F-1:1.2. Age group-16-75yrs. Masses classified as solid in 8 patients (40%) and cystic in 12 (60%). Solid masses included neuroendocrinal tumors (62.5%); metastasis (25%) and chronic inflammatory mass (12.5%). Cystic masses were mucinous cystadenoma (37.3%), serous cystadenoma (25%), simple cyst (16.6%), intraductal papillary mucinous tumor, pancreatic tuberculosis and mucinous cystadenomacarcinoma in 8.3% each. Cystic masses were common in females 64.4% as compared to 55.5% in males. Pancreatic endocrine masses were characteristically hypervascular on arterial phase. Metastasis was seen from renal cell carcinoma and lung mass. Mucinous cystadenoma were the commonest cystic masses measuring more than10-12 cms with multiple septa, internal cyst varying <6-7 in number and size >2cms. Serous cystadenoma were approximately 5-6 cms in size with small internal cysts <2cms with septations. Cysts associated with syndromes like von Hippel Lindau and polycystic kidney disease and pancreatic tuberculosis was seen in one patient each. Conclusion: Uncommon pancreatic masses have characteristic features which help in triage and prognosis of the patients. [ABSTRACT FROM AUTHOR]

Diffuse alveolar haemorrhage is a serious manifestation of granulomatosis with polyangitis (Wegener's) with high morbidity and mortality. It is defined by the clinical triad of haemoptysis, anaemia and progressive hypoxaemia. [ABSTRACT FROM AUTHOR]

To conclude, bilateral breast metastases from the undifferentiated carcinoma of nasopharynx are rare. Breast metastases are commonly confused with the more common primary carcinoma of breast. Diagnosis is based on the core needle biopsy of the lesion which is helpful in the appropriate treatment planning of the patient. [ABSTRACT FROM AUTHOR]
