Comparative diagnostic value of contrast-enhanced ultrasonography, computed tomography, and magnetic resonance imaging in diagnosis of hepatic hemangiomas

Aim. To compare the value of intravenous contrast-enhanced ultrasonography (US), intravenous contrast-enhanced computed tomography (CT), and magnetic resonance imaging (MRI) in the diagnosis of hepatic hemangiomas. Material and methods. The study enrolled 48 patients, aged between 20 and 79 years (35 [72.9%] women, 13 [27.1%] men; mean age, 53.5±12.855 years), who were examined and treated in the Departments of Gastroenterology, Surgery, and Oncology, Hospital of Kaunas University of Medicine, in the year 2007. All patients underwent intravenous contrast-enhanced US, intravenous contrast-enhanced CT, and MRI and were diagnosed with hepatic hemangioma according to the findings of these examinations. Results. The size of hemangiomas was ≤2.0 cm in 20 cases (41.7%) and >2.0 cm in 28 (58.3%). No association between hepatic hemangioma and patient’s age was found (χ2=0.547, df=2, P=0.761). Nearly one-third of hemangiomas were located in the segment IV of the left hepatic lobe. There were a few complicated hemangiomas in the study sample: 2 with calcification and 1 with necrosis. The sensitivity of CT in the diagnosis of hepatic hemangioma was 76.92%; specificity, 33.3%; positive prognostic value, 83.3%; and negative prognostic value, 25.0%. The sensitivity of intravenous contrast-enhanced US in the diagnosis of hepatic hemangioma was 77.8%; specificity, 100%; positive prognostic value, 100%; and negative prognostic value, 23.1%. Conclusions. Intravenous contrast-enhanced US is more specific than intravenous contrast-enhanced CT in the diagnosis of hepatic hemangioma (P=0.0005) and has a higher positive prognostic value (P=0.001).

Hepatic Hemangiomas

Hemangiomas are benign vascular tumors caused by an increase of blood vessels lined with endothelium. Diagnostic imaging such as sonography, computed tomography (CT), and contrast-enhanced magnetic resonance imaging (CE-MRI) can be used to detect hepatic hemangiomas, which are typically noted as incidental findings. However, in cases where hepatic hemangiomas demonstrate atypical appearances, this may suggest a possible malignancy. In such instances, a liver biopsy may be necessary for pathologic confirmation. A case is provided of a large hepatic mass that was initially detected on CT and further evaluated with sonography. Sonographic evaluation revealed characteristics suspicious for possible malignancy, including highly enlarged size, heterogeneous echotexture, and lobular contour. A biopsy ultimately determined the mass to be a cavernous hepatic hemangioma. The atypical sonographic appearance of the hepatic hemangioma in this case is worthy of consideration such that sonographers and the interpreting physician are aware of various presentations of this pathology.
