Highlight ■ This method enables surgeons to visually identify the lesion pathway without intraoperative imaging, enhancing precision and workflow. ■ A practical, cost-effective alternative to high-end technologies such as electromagnetic navigation bronchoscopy and hybrid operating rooms. ■ Metallic wires offer excellent intraoperative visibility on the lung surface, supporting their clinical utility. ■ All nonpalpable nodules were successfully resected, with no complications related to the preoperative localization procedure. ■ CT-guided preoperative localization of nonpalpable pulmonary lesions using a purpose-built device demonstrates […]

ABSTRACT The increasing use of videolaparoscopy for the complete excision of endometriotic lesions and restoration of pelvic anatomy has helped improve long-term outcomes. However, risks remain, including rare but significant complications such as salpingoureteral fistulas. Early diagnosis using imaging methods enables adequate treatment and reduces the risk of new complications. In this report, we present a case of uretero-fallopian fistula following gynecological surgery for the resection of endometriotic lesions, with intraoperative inadvertent ureteral injury. This case report aimed to highlight […]

ABSTRACT Incidentalomas are lesions incidentally identified in patients undergoing imaging for unrelated reasons. Breast incidentalomas have a high correlation with malignancy, occurring in over 40% of cases. Consequently, their interpretation poses significant challenges for radiologists who must discern the findings that may present a potential risk to the patient. This pictorial review presents different incidental breast lesions revealed through cross-sectional imaging. We further review key concepts related to such incidentalomas.

Highlights ■ The use of a pedicled palatal flap via the soft palate offers the advantage of low harvesting complexity. ■ The flap demonstrates highly positive metric data supporting its technical feasibility for reconstructing the skull base and adjacent regions. ■ Drilling is not necessary to enlarge the greater palatine foramen in this technique, which reduces the chances of injury to the vascular pedicle and surgical time. ABSTRACT Objective: Given the importance of vascularized flaps, this study presents a new […]

ABSTRACT Spontaneous non-aneurysmal aortic rupture is rare and is usually attributed to penetrating aortic ulcers, infections, tumor infiltrations, or inflammatory and collagen diseases. Chronic rupture is infrequent but extremely rare in non-aneurysmal aortas, which makes diagnosis difficult because the absence of an aneurysm can mislead the physician to rule out rupture. Here, we describe the case of an 85-year-old male, who was undergoing oncological investigation for weight loss, inappetence, and back pain. Computed tomography and magnetic resonance imaging performed 3 […]

ABSTRACT The focus of this case report is to technically describe a noninvasive diagnostic evaluation of bow Hunter’s syndrome using a dynamic computed tomography angiography protocol and discuss its advantages. In addition, we aimed to exemplify the quality of the study by presenting images of a 3D-printed model generated to help plan the surgical treatment for the patient. The dynamic computed tomography angiography protocol consisted of a first image acquisition with the patient in the anatomic position of the head […]

Highlights Computed tomography revealed fibrotic-like lung changes in 10.9% of patients. Higher computed tomography scores were associated with a reduced DLCO (median computed tomography score, 6 versus 3; p=0.016). Fibrotic-like computed tomography changes were more prevalent in patients with DLCO impairment (p<0.001). Reduced DLCO had sensitivity and specificity of 73% and 88%, respectively, for predicting fibrotic-like computed tomography changes. ABSTRACT Objective: The radiological and functional lung sequelae in COVID-19 survivors remain unclear. We compared the chest computed tomography findings of […]

ABSTRACT Pulmonary aspiration of gastric residues during anesthesia is a potentially fatal complication for which no specific treatment is available. The primary way to prevent its occurrence in the context of elective surgeries is adherence to fasting protocols. However, some clinical conditions can prolong the gastric emptying time, and the risk of aspiration may exist despite adequate fasting. Recognizing the risk factors for gastroparesis allows the adoption of preventive methods and is the primary way to reduce morbidity and mortality […]

ABSTRACT Objective To compare inter-rater reliability, diagnostic accuracy, and extension of pulmonary involvement in children with suspected COVID-19 submitted to supine or supine and lateral decubitus computed tomography imaging. Methods Retrospective study carried out between March 2020 and March 2021 with patients submitted to reverse transcription-polymerase chain reaction testing and chest computed tomography. Patients were divided into two groups: supine or supine and lateral decubitus imaging. Standardized reporting systems of computed tomographic findings in COVID-19 and chest computed tomography score […]

RESUMO Objetivo Avaliar a acurácia de uma estratégia de rastreamento de hipertensão pulmonar baseada na combinação de dados de ecocardiograma com as medidas derivadas da tomografia computadorizada (diâmetro da artéria pulmonar e razão entre diâmetro da artéria pulmonar e diâmetro da aorta ascendente) em pacientes pneumopatas crônicos encaminhados para transplante pulmonar. Métodos Estudo observacional retrospectivo realizado com pacientes com enfisema e fibrose pulmonar avaliados para transplante entre 2012 e 2016. Definiu-se hipertensão pulmonar como pressão arterial pulmonar média ≥25mmHg, ou […]
