“…With the dissemination of imaging diagnosis devices as well as their increasingly widespread utilization, the occurrence of incidentally found hepatic nodules has become more and more frequent in patients submitted to imaging studies or screening for tumors (48)(49)(50)(51) . The technological development of these apparatuses has allowed the detection of increasingly smaller lesions, difficulting their characterization that later might be affected by the findings of pseudo-hepatic lesions at contrast-en-hanced CT and MRI (52,53) .…”

Uma grande variedade de tumores benignos e malignos ocorre no fígado. Embora a caracterização de lesões hepáticas focais possa ser um desafio para o radiologista, a maioria das lesões se apresenta com características de imagem que permitem o seu diagnóstico. O objetivo deste trabalho é o de rever os principais aspectos de imagem dos tumores hepáticos benignos e malignos mais comumente encontrados no fígado adulto.

“…Typically, the conventional exam is repeated after 3 to 6 months, and no other imaging exams are done. Some authors recommend a CT or MR in all cases of nodules greater than 1 mm (13,14) . Use of contrast in US has brought new perspectives to the method, and this approach is gradually becoming adopted in hepatology for the differential diagnosis of hepatic nodules, detection of primary carcinomas, transplant assessment, among others (12) .…”

-Context -The incidence of hepatic hemangiomas ranges from 0.4% to 20% in the general population. Conventional ultrasound is usually the first diagnostic method to identify these hemangiomas, typically as an incidental finding. Ultrasonography with second generation contrast materials is being used in various areas of hepatology, yielding similar results to those obtained with computerized tomography and magnetic resonance imaging in the diagnosis of hepatic hemangiomas. Objective -To evaluate the agreement between ultrasound with perflutrene contrast and magnetic resonance imaging in the diagnosis of hepatic hemangiomas.Methods -A total of 37 patients were prospectively examined between January 2006 and August 2008. A total of 57 hepatic nodules were documented in this group as incidental findings on routine ultrasound exams. The 37 patients were administered perflutrene contrast without adverse reactions, and were all submitted to magnetic resonance exams. Results -Conventional ultrasound identified 15 patients with nodules typical of hemangiomas and 22 patients with other nodules. In 35 patients, the contrast characteristics were consistent with hepatic hemangiomas. Conclusion -Agreement between the data obtained from ultrasound with contrast and magnetic resonance was 94.5%. In discordant cases, the magnetic resonance diagnosis prevailed. In the case which presented indeterminate findings on contrast ultrasonography, magnetic resonance was repeated after 3 months, confirming the diagnosis of a hepatic hemangioma. A biopsy was performed on the suspected malignant nodule which also confirmed the presence of a hepatic hemangioma. Ultrasonography with contrast has the advantages of being more accessible to the public at large and lower cost than magnetic resonance. The results of our study highlight the need for a new protocol in hepatic nodules incidentally identified on conventional ultrasonography. In the case of typical hemangiomas, conventional ultrasound is sufficient for diagnosis. However, for poorly defined nodules, ultrasonography with contrast is indicated. After confirming the presence of a hepatic hemangioma on contrast ultrasonography, no further exams are needed to finalize the diagnosis.

O hemangioma hepático é frequentemente assintomático e, mesmo quando de grandes dimensões, não mostra tendência a sangramento. Os autores relatam o caso de uma paciente de 31 anos de idade com dor abdominal aguda, cujos exames de imagem evidenciaram hematoma no lobo hepático esquerdo, associado a hemoperitônio. A paciente foi submetida a hepatectomia esquerda, com o diagnóstico histopatológico de hemangioma cavernoso.
