Role of Computerized Tomographic Findings in Cases of Focal Hepatic Lesions
MVP Journal of Medical Sciences, 2019
Introduction: Focal Hepatic Lesions (FHL) has been a common reason for consultation faced by medical consultants. With the widespread use of imaging studies led to an increase in detection of incidental focal liver lesions. It is important to consider both malignant liver lesions as well as benign solid and cystic liver lesions such as hemangioma, focal nodular hyperplasia, hepatocellular adenoma, and hepatic cysts, in the differential diagnosis. Objectives: Our aim was to study the computerized tomographic finding in the various focal hepatic lesions and also to study the various enhancement pattern of the focal hepatic lesion. Materials and Methods: CT scan study of abdomen and pelvis was done on 100 patients from August 2015 to December 2017 over a period of the 2 years. Patients, irrespective of age and sex referred to radiology department of our institute on IPD or OPD basis were included in the study. All patients will be subjected to computerized tomography of the abdomen with CT (Siemens Somatom Emotion 6) machine and Somatom Essenza. Results: Total 100 patients were studied for various focal hepatic lesions out of which 64(64%) were male patients and 36(36%) were female patients. The most common affected age group encountered in our study was 51-60 years. Various focal hepatic lesions were reported in which 64(64%) patient had malignant nature of lesion with most common pathology detected was hepatic metastasis seen in 37(37%) patient. On other hand benign lesion were evident in the 36(36%) patient with hemangioma as most common pathology in this category. Conclusion: Multi-detector Computed Tomography (MDCT) with a correlation of triple phase study is an excellent tool for diagnosis of the focal liver lesion by learning the degree and pattern of enhancement in all three phase thus helping in better characterization of the lesion. MDCT allows the reconstruction and reformation of images supported in detecting multiple lesions and early diagnosis of a focal lesion in the presence diffuse liver condition.
Triphasic computed tomography (CT) scan in focal tumoral liver lesions
JPMA. The Journal of the Pakistan Medical Association, 2011
To assess the diagnostic accuracy of triphasic spiral CT in differentiating benign from malignant focal tumoral liver lesions. The study was conducted in Department of Radiology of Aga Khan University Hospital and Sind Institute of Urology and Transplantation, Karachi from Feb 2006 to Feb 2007. By convenient sampling, 45 patients found to have focal tumoral liver lesions were recruited for one year period and their triphasic CT scans findings were evaluated and later correlated with histopathology. Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of triphasic CT scan were calculated. Among 45 patients, 136 liver lesions (11 benign and 125 malignant) were detected with the help of different enhancement patterns. Out of these, 37(82.2%) patients had malignant while 8 (17.8%) had benign lesions. On later histopathological examination, 35 (77.8%) of the total 45 cases had malignant lesions while 10 (22.2%) were diagnosed as benign le...
Study of Liver Lesions using Computed Tomography
This study aimed to study the role of computed tomography (CT) in the diagnosis of liver lesions, to determine which lesion of the liver with high incidence, and to find out the Geographic distribution of the liver lesions in Sudan. This is a retrospective study was conducted at Fedail hospital, and Royal scan Center, Khartoum, Sudan included Sixty patients with focal liver lesions. The results of the study revealed that the high incidence of liver lesions was (45%) among the age group between (41-60) years old. The high incidence of liver lesions was metastasis (33.3%) and solid mass (33.3%) affected age group (41-60) years old (45%), it commonest in male (60%), most patients from center, north, and west of Sudan. The solid mass of the liver was commonest in age group (61-80) years old had an incidence of (45%), it commonest in male (65 and the most affected was right lobe of the liver (50%). This study concluded that triphasic CT scan is a good non-invasive tool and can be used as the first line for differentiating of focal liver lesions. Benign lesions like haemangioma can be reliably differentiated from malignant liver lesion; therefore unnecessary biopsies can be avoided.

MRI characterization of 124 CT-indeterminate focal hepatic lesions: evaluation of clinical utility
HPB, 2007
Objective. To evaluate the diagnostic yield of MRI performed for characterization of focal hepatic lesions that are interpreted as indeterminate on CT. Patients and methods. In a retrospective investigation, 124 indeterminate focal hepatic lesions in 96 patients were identified on CT examinations over 5 years from 1997 to 2001. All patients had MRI performed for the liver within 6 weeks of their CT examination. CT and MR images were reviewed independently by two separate groups of two radiologists. The value of MRI in characterizing these lesions was assessed. Diagnoses were confirmed based on histology, characteristic imaging features, and clinical follow-up. Results. MRI definitely characterized 73 lesions (58%) that were indeterminate on CT. MRI was accurate in 72/73 of these lesions. MRI could not definitely characterize 51 lesions (42%). Ten lesions were not visualized on MRI, and follow-up imaging confirmed that no lesion was present in eight of these cases (pseudolesions). Conclusion. MRI is valuable for the characterization of indeterminate focal hepatic lesions detected on CT.
Non-invasive diagnosis of focal liver lesions: an individualized approach
Cancer Imaging, 2012
Modern cross-sectional imaging with multidetector computed tomography (MDCT) or magnetic resonance imaging (MRI) often reveals small focal liver lesions, which puts pressure on the reporting radiologist to characterize these tiny lesions. On the other hand, in patients with underlying diffuse liver disease, such as cirrhosis or severe steatosis, the detection of focal liver lesions can be quite difficult. Strategies for optimal detection and characterization of focal liver lesions should be developed according to the clinical situation, the likelihood of malignant disease and the presence of underlying diffuse liver disease. The presence or absence of a clinical history of cancer determines the algorithm for further characterization: work-up with contrast-enhanced MRI, biopsy or follow-up. In patients with chronic liver disease, recent guidelines on the detection of hepatocellular carcinoma (HCC) favour the use of multiphasic MRI or MDCT, which allows confident diagnoses of HCC 41 cm. For lesions 51 cm in chronic liver disease, follow-up is recommended. In patients with moderate to severe steatosis, contrast-enhanced MDCT has low diagnostic yield for the detection of liver lesions; contrast-enhanced MRI is far superior. This review describes successful strategies for the detection and characterization of focal liver lesions in different clinical scenarios.
Journal of Gastrointestinal and Liver Diseases
Background and Aims: Despite the undeniable ongoing development of cross-sectional imaging methods, not all focal liver lesions (FLLs) have a typical pattern. An image-guided biopsy using a percutaneous approach might safely provide a final histological diagnosis of the FLLs. We aimed to evaluate the accuracy, efficiency, complication rate, technical features, and relationships between the followed parameters of computed tomography (CT)-guided percutaneous biopsies of FLLs using a retrospective approach. Methods: 303 percutaneous biopsy procedures in 295 patients were carried out in patients with suspected or indeterminate FLLs over a 10-year period. The median size of the tumors was 44 mm (15 - 144 mm). Median age of patients was 67 years (25 to 87 years). Skin-to-lesion distance was variable, from 30 mm to 138 mm (median length 59 mm). In 200 procedures (66%) malignant disease was known from the patients´ clinical history. Results: In 288 biopsies (95%) the results were true posit...
