Objectives: The aims of this study were: (a) to evaluate the performance of an artificial intelligence (AI) software package (Boneview Trauma, Gleamer) for the detection of post-traumatic bone fractures in radiography as a standalone; (b) used by two radiologists (osteoarticular senior and junior); and (c) to determine to whom AI would be most helpful.

Materials and methods: Within 14 days of a trauma, 101 consecutive patients underwent radiographic examination of the upper or lower limbs. The definite diagnosis for identifying fractures was: (a) radio-clinical consensus between the radiologist on-call who analyzed the images and the orthopedist (Group 1); (b) Cone Beam computed tomography (CBCT) exploration of the area of interest, in case of doubts or absence of consensus (Group 2). Independently of this diagnosis for both groups, the radiographic images were separately analyzed by two radiologists (osteoarticular senior: SR; junior: JR) prior without, and thereafter with the results of AI.

Results: AI performed better than the radiologists in detecting common fractures (Group 1), but not subtle fractures (Group 2). In association with AI, both radiologists increased their overall performances in both groups, whereas this increase was significantly higher for the JR (p < 0.05).

Conclusion: AI is reliable for common radiographic fracture identification and is a useful learning tool for radiologists in training. However, the software's overall performance does not exceed that of an osteoarticular senior radiologist, particularly in case of subtle lesions.

Teaching point: Microcystic lymphangioma is a rare but benign lesion that should be differentiated from a neoplasm.

Teaching point: Computed tomography is essential for timely diagnosing infected mesenteric cysts as a cause of acute abdomen, ultimately requiring complete excision to confirm diagnosis given the potential of malignant transformation.

Teaching point: The appearance of an avulsion of the ossification center of the iliac crest is reported on ultrasound, radiographs, and magnetic resonance imaging (MRI), with emphasis on the role of the "pseudo-CT" zero echo time (oZTEo) sequence to highlight the lesion.

Teaching point: Due to the mass-like appearance of pulmonary histoplasmosis in the lung, radiological misdiagnosis may occur. Fungal infections should be considered in the differential diagnosis, especially in immune-compromised patients.

The most common cause of peripheral arterial disease (PAD) is atherosclerosis. PAD can be considered a global pandemic, as it affected a quarter billion people worldwide in 2013 [1]. The prevalence and complexity of the disease is increasing due to aging populations and the rise in risk factors including diabetes and kidney disease.

Objectives: To evaluate the imaging characteristics of the tumor, emphasizing its location, and to determine the frequency of typical and atypical locations of olfactory neuroblastoma (ONB).

Materials and methods: We retrospectively reviewed the computed tomography and magnetic resonance imaging findings of patients with pathologically proven ONB between April 2000 and April 2023. Demographic information, chief complaints, tumor location, and tumor extension were extracted.

Results: Of the 58 patients, 50 (86.2%) had the epicenter of the mass at the superior part of the nasal cavity, while eight patients (13.8%) had the epicenter at other atypical locations: seven patients (12.1%) at the middle part of the nasal cavity and one patient (1.7%) within both sphenoid sinuses.

Conclusion: ONB is not always present in the upper part or the roof of the nasal cavity, and a significant number of ONBs are occasionally found in the rest of the nasal cavity and other atypical locations.

Teaching point: While demanding urgent management, limited intimal tear (LIT), a rare subtype of acute aortic syndrome (AAS), poses challenges in terms of accurate and timely diagnosis.
