Hemobilia in a patient with arteriobiliary fistula after liver contusion
Abstract Sarcomas of the breast belong to a heterogeneous group of breast tumors of mesenchymal origin, without epithelial components. These tumors can be primary or secondary (after previous treatment for breast cancer), are rare, present aggressive behavior, and have a poor prognosis. They occur mainly in women between 45 and 50 years of age, with the exception of angiosarcomas, which can occur in younger patients. Clinically, breast sarcomas manifest as palpable, mobile, rapidly growing masses, without skin thickening, axillary lymphadenopathy, or nipple discharge. Although the imaging findings are non specific, they ca...

Practical approach to primary retroperitoneal masses in adults
Abstract Primary retroperitoneal masses constitute a heterogeneous group of uncommon lesions and represent a challenge due to overlapping imaging findings. Most are malignant lesions. Although they are more prevalent in adults, they can occur at any age. Such lesions are classified as primary when they do not originate from a specific retroperitoneal organ and are divided, according to the image findings, into two major groups: solid and cystic. The clinical findings are nonspecific and vary depending on the location of the lesion in relation to adjacent structures, as well as on its behavior. The main imaging methods used...

Pulmonary inhalation-perfusion scintigraphy in the evaluation of bronchoscopic treatment of bronchopleural fistula
Conclusion: We found pulmonary inhalation-perfusion scintigraphy to be a useful tool for identifying a residual BPF, as well as being an alternative method of investigating BPFs and of monitoring the affected patients.Resumo Objetivo: Avaliar a cintilografia por inala ção-perfusão pulmonar como método alternativo de investigação e acompanhamento em pacientes com fístula broncopleural (FBP). Materiais e Métodos: Nove pacientes com FBPs foram tratados de forma endoscópica com o uso off label de um oclusor transcateter de defeito do septo interatrial e for am seguidos com cintilografia de inalação-perfusão pulmo...

Value of ultrasound in the anatomical evaluation of the brachial plexus: correlation with magnetic resonance imaging
Conclusion: In the brachial plexus, ultrasound can be used in the assessment of the cervical nerve roots, as well as of the upper and middle trunks, although it provides limited visualization of the remaining segments. Ultrasound and MRI showed a high level of agreement for the visualization of the C6, C7, and middle trunk segments.Resumo Objetivo: Avaliar a efic ácia do exame de ultrassonografia (US) na visualização do plexo braquial e avaliar o método comparativamente à ressonância magnética (RM).
