Role of ultrasonography in diagnosis of solid space occupying lesion in the liver correlation with FNAC
AbstractThis cross sectional study was carried enrolling 47 subjects with suspected solid liver mass, in the Department of Radiology and Imaging, Dhaka Medical College Hospital, Dhaka, over a period of twelve months. The aim of this study was to evaluate the diagnostic usefulness of transabdominal ultrasonography in the diagnosis of solid SOL in the liver. Majority of the respondents (42.55%) were found between 41-60 years of age. Five (10.63%) subjects were found below 20 years of age. There were 31 men (65.95%) and 16 women (34.05%). Majority of the metastasis were multiple (85%), hypoechoic (35%) and only 15% had internal calcifications. HCC was single lesion (61.53%) with hyperechoic (38.35%) echogenicity, with a central halo (76.92%) and 15.38% had internal calcifications. Majority of the cholangiocarcinoma were solitary (80%), hypoechoic (60%) and 60% had internal calcifications. Hepatoblastoma were solitary and had calcifications (60%) with mixed echogenicity (60%). Majority of the adenomas were solitary (80%), hypoechoic (60%) and only 20 % had internal calcifications. The validity of transabdominal sonography for the diagnosis of metastasis was confirmed by calculating sensitivity (100%), specificity (96.42%), accuracy (97.87%), positive (95%) and negative predictive (100%) values by using the standard formula given. The sensitivity, specificity, accuracy, positive and negative predictive values for HCC were 92.3%, 97.05%, 95.74%, 92.3% and 97.05% respectively. The sensitivity, specificity, accuracy, positive and negative predictive values for cholangiocarcinoma and hepatoblastoma were 80%, 97.61%, 95.74%, 80% and 97.61% respectively. Sensitivity, specificity, accuracy, positive and negative predictive values were 80%, 100%, 97.87%, 100% and 97.67% respectively for adenoma. From the study result it was concluded that transabdominal ultrasonography could be reliable, non-ionizing and relatively cheap procedure for diagnosis solid hepatic mass lesion.
