Calcificações hepáticas: freqüência e significado

Abstract: OBJETIVO: Avaliar a freqüência e a origem de calcificações hepáticas identificadas na tomografia computadorizada (TC). MATERIAIS E MÉTODOS: Estudo retrospectivo de 1.362 exames consecutivos de TC do abdome, para determinar a freqüência de calcificações hepáticas. Foram revistos os prontuários clínicos, no sentido de estabelecer a origem das calcificações. RESULTADOS: Observaram-se calcificações intra-hepáticas em 3,6% (49/1.362) dos exames. Houve predominância no sexo feminino (57,2%) sobre o masculino (42,8%)… Show more

“…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) . Recognizing the main imaging findings of the most frequent hepatic tumors and some of their characteristics (54) may positive and definitely help the radiologist in the approach and management of this group of patients. A B C Figure 12.…”

“…One patient presented a hepatic punctiform calcification, with no associated perfusional alteration and identified only in the second analysis. It is important to note that this type of calcification has no pathological meaning and is frequently found in asymptomatic patients (23) . One patient had an indeterminate adrenal nodule identified in the contrast-enhanced phase, and considered as compatible with adenoma because of the level of density observed in the unenhanced phase (second analysis).…”

“…Calcificações podem ocorrer em 7,5-25% dos hepatocarcinomas (12,39) , mas na nossa experiência ocorreram em apenas 5% dos pacientes estudados (Figura 15). É importante lembrar que a presença de calcificação hepática sem alteração textural ou perfusional local deve ser considerada de provável origem residual (40) .…”
