Pseudoaneurysm after an ultrasound-guided breast core needle biopsy in a lactating woman.

This is a case report of a lactating woman in her twenties diagnosed with a breast pseudoaneurysm following a 14-gauge ultrasound-guided core needle biopsy detected by a Color Doppler exam, and treated with surgery. Further discussion concerning the patient's symptoms, useful imaging modalities, and treatment options are included. Knowledge on this complication is crucial for the correct diagnosis and best management and treatment.

Gray-scale sonography of solid breast masses: diagnosis of probably benign masses and reduction of the number of biopsies.

PURPOSE: To identify probably benign breast masses using gray-scale sonography and to see if this strategy could reduce the number of biopsies of breast masses. METHODS: This retrospective study included 229 masses in 203 women who underwent sonographically guided percutaneous biopsy. Masses with a negative predictive value for malignancy >98% were retrospectively considered probably benign, and the potential impact of gray-scale sonography in reducing the number of biopsies if these masses were not biopsied was assessed. Assessments were performed considering all masses as a group as well as various subgroups. RESULTS: Round, ellipsoid, or lobulated masses with 3 or fewer lobulations, circumscribed margins, a longitudinal-anteroposterior diameter ratio > or =1.0 and no marked hypoechogenicity, posterior acoustic shad owing, internal microcalcifications, or altered surrounding breast tissue were considered probably benign. The sensitivity of gray-scale sonography to identify this subgroup was 98%, with a negative predictive value of 99%. If these masses were not biopsied, there would be a 42% reduction in the number of biopsies considering all masses, a 36% reduction for masses classified as Breast Imaging Reporting and Data System category 4, and a 59% reduction for masses exclusively analyzed with sonography. CONCLUSIONS: It is possible to identify probably benign breast masses using gray-scale sonography, and thereby to reduce the number of biopsies performed.

Fat necrosis of the breast: mammographic, sonographic, computed tomography, and magnetic resonance imaging findings.

Fat necrosis of the breast is a benign inflammatory process that may be mistaken for cancer in clinical examination or imaging studies. Although its mammographic manifestations are well known, data from other imaging modes, particularly sonography and magnetic resonance imaging, are limited. With the growing number of breast surgeries performed today (eg, breast-conserving, autologous tissue reconstruction, mammoplasty), fat necrosis is seen more often in daily practice. Knowledge of its imaging features could improve clinical management, including the avoidance of unnecessary biopsy procedures. The main objectives of this article are to review the literature and to relate the manifestations of fat necrosis on mammography, sonography, magnetic resonance imaging, and computed tomography to their associated histopathologic events.

Intussuscepção jejunojejunal em adulto - relato de um caso e revisão da literatura / Adult jejunojejunal intussusception - a case report and review of the literature

Os autores apresentam um caso de intussuscepção jejunojejunal em adulto, no qual um pólipo adenomatoso foi o fator causal. A grande maioria dos casos de intussuscepção acomete crianças abaixo dos dois anos de idade, com incidência de somente 5 por cento a 15 por cento em adultos. Ao contrário do grupo pediátrico, em que 90 por cento dos casos são considerados idiopáticos, a intussuscepção no adulto possui fator causal demonstrável em mais de 90 por cento das ocorrências. O diagnóstico pré-operatório é feito com base no quadro clínico, associado aos achados da radiologia convencional, estudo contrastado do intestino, ultra-sonografia e tomografia computadorizada, descritos e dicutidos neste estudo.
