Uretero-fallopian fistula after gynecological surgery for endometriosis: a case report
DOI: 10.31744/einstein_journal/2025RC1294
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 […]

Incidentally detected breast lesions: a pictorial essay of malignant and benign findings
DOI: 10.31744/einstein_journal/2025RW0681
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.

Modified palatal flap via soft palate for skull base reconstruction
DOI: 10.31744/einstein_journal/2025AO1247
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 […]

Chronic spontaneous non-aneurysmal aortic rupture treated with endovascular surgery
DOI: 10.31744/einstein_journal/2024RC1113
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 […]

Dynamic computed tomography angiography for noninvasive diagnosis of bow Hunter’s syndrome: a case report
DOI: 10.31744/einstein_journal/2024RC0582
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 […]

Correlation between chest computed tomography findings and pulmonary function test results in the post-recovery phase of COVID-19
DOI: 10.31744/einstein_journal/2023AO0288
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 […]

Risk of pulmonary aspiration during semaglutide use and anesthesia in a fasting patient: a case report with tomographic evidence
DOI: 10.31744/einstein_journal/2023RC0628
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 […]
