ABSTRACT
Abstract The full spectrum of COVID-19 is still emerging, although several studies have highlighted that patients infected with the novel coronavirus can potentially develop a hypercoagulable state. However, several aspects related to the incidence and pathophysiology of the association between COVID-19 and pulmonary embolism are not well established. Here, we present a case of a patient with COVID-19 who developed acute pulmonary embolism. Clinical and laboratory data and findings of non-enhanced CT indicate possibility of acute pulmonary embolism, and support the decision to proceed with computed tomography pulmonary angiography that can objectively identify filling defects in pulmonary arterial branches.

Transrectal ultrasonography-guided biopsy plays a key role in prostate sampling for cancer detection. Among interventional procedures, it is one of the most frequent procedures performed by radiologists. Despite the safety and low morbidity of such procedure, possible complications should be promptly assessed and treated. The standardization of protocols and of preprocedural preparation is aimed at minimizing complications as well as expediting their management. The authors have made a literature review describing the possible complications related to transrectal ultrasonography-guided prostate biopsy, and discuss their management and guidance to reduce the incidence of such complications.
ABSTRACT
Carcinoma primário de ovário raramente origina metástase para mama, com poucos casos descritos na literatura. Os autores relatam um caso de uma paciente com carcinoma ovariano que evoluiu com metástase para mama após cerca de oito anos do diagnóstico inicial da neoplasia e realizam revisão bibliográfica do assunto, dando ênfase aos aspectos de imagem.
Primary ovarian carcinoma rarely metastasizes to the breast, and few cases are described in the literature. The authors report the case of a patient with ovarian carcinoma that developed breast metastasis eight years after the initial diagnosis, and present a literature review on this subject, emphasizing imaging findings.
