RESUMEN
Inverted intercostal hernias are uncommon, and even more so when comprised of soft tissue instead of lung parenchyma in the postoperative context. This report demonstrates a case in with such a hernia was diagnosed through chest multidetector computerized tomography in a 48-year-old woman who presented to the emergency room with respiratory symptoms and tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). She had positive surgical history for left lower lobectomy with bronchoplastic procedure and mediastinal lymphadenectomy, due to an endobronchial typical carcinoid tumor a few years ago. Therefore, it is important for radiologists to be aware of the imaging characteristics of inverted intercostal hernias, to avoid diagnostic errors.
RESUMEN
Mediastinal fat necrosis is an important differential diagnosis for acute chest pain in previously healthy patients. Imaging examination is essential to establish this diagnosis, as physical examination can be unhelpful and laboratory tests are non-specific. The treatment of choice is conservative, with non-steroidal anti-inflammatory drugs; surgery is reserved for a few selected cases. We present the case of a 37-year-old male patient with mediastinal fat necrosis, refractory to the conservative management and complicated by growing pleural effusion, which was treated surgically.
RESUMEN
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.

Transthoracic needle biopsy with fluoroscopic or computed tomographic guidance is a well-established and safe method for diagnosing malignant and benign thoracic lesions. Nonetheless, ultrasound is as effective as computed tomography for the guidance of transthoracic biopsies of peripheral pulmonary lesions and mediastinal tumors, and it offers some advantages. In this case report, we exemplify the proper use of ultrasound for the percutaneous biopsy of a lung lesion, aiming to show that it can be a safe, inexpensive, rapid, and effective alternative to computed tomography in appropriate cases.

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.
RESUMEN
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.
