Tracheobronchial Diverticulosis.

Tracheal diverticulosis is a rare and benign disorder, characterized by single or multiple tracheal wall outpouchings, either congenital or acquired, usually diagnosed incidentally on chest high‑resolution computed tomography, and in general remaining asymptomatic.

Pleuropulmonary Epithelioid Hemangioendothelioma.

We present the CT, thoracoscopic, and histological findings of a 55-year-old female with pleuropulmonary epithelioid hemangioendothelioma. The CT scan revealed pleuropulmonary lesions, and thoracoscopy allowed direct visualization and biopsy of the lesions. Histological analysis confirmed the diagnosis, emphasizing the utility of combining imaging, endoscopic, and pathological methods in diagnosing this rare tumor.

Mega Virchow-Robin.

Perivascular spaces, also known as Virchow-Robin spaces, are fluid-filled spaces that surround the vessel walls from the subarachnoid space through the brain parenchyma.

Unusual Air Crescents on Chest Radiographs.

The air crescent (AC) is a common radiological sign. Even if its commonest aetiology remains pulmonary aspergillosis, various other causes have been described. In this study, we report four rare causes of ACs seen on chest radiographs that haven't been described in the literature.

Radiographic Detection of Post-Traumatic Bone Fractures: Contribution of Artificial Intelligence Software to the Analysis of Senior and Junior Radiologists.

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).
