Rare complication of a common procedure: Pneumomediastinum following an endodontic procedure.

Pneumomediastinum is a rare but potentially serious complication characterized by the presence of air within mediastinal structures. Although it is typically associated with thoracic trauma or vigorous coughing, it can also occur following dental procedures involving high-speed air-turbine drills. During these procedures, air can enter the cervical fascial planes and potentially extend to the mediastinum, leading to risks like deep neck infections or mediastinitis.

An overlooked cause of groin pain: Ischiofemoral impingement syndrome.

BackgroundIschiofemoral impingement syndrome (IFI) is a condition characterized by narrowing of the space between the ischium and femur, potentially compressing the quadratus femoris muscle. Although associated with hip pain, its role in groin pain is underexplored.ObjectiveTo assess the relationship between IFI and groin pain and examine the association between quadratus femoris muscle edema and ischiofemoral space (IFS) and quadratus femoris space (QFS) measurements.

ChatGPT-4o's Performance in Brain Tumor Diagnosis and MRI Findings: A Comparative Analysis with Radiologists.

Rationale And Objectives: To evaluate the accuracy of ChatGPT-4o in identifying magnetic resonance imaging (MRI) findings and diagnosing brain tumors by comparing its performance with that of experienced radiologists.

Materials And Methods: This retrospective study included 46 patients with pathologically confirmed brain tumors who underwent preoperative MRI between January 2021 and October 2024. Two experienced radiologists and ChatGPT 4o independently evaluated the anonymized MRI images.

Effectiveness of Flow Diverter Stents in the Treatment of Intracranial Aneurysms: Single-Center 10-Year Results.

Purpose This study's objective was to show how effectively flow-diverting stents work when treating cerebral aneurysms. The assessment aimed to determine efficaciousness related to aneurysm type, size, and location as well as early- and late-term results. Material and method The study included 153 aneurysms from 122 patients treated in interventional radiology unit with flow diverter stents between July 2010 and June 2020.

Radiological and biomechanical evaluation of the ulnar nerve after the percutaneous application of the medial K-wire in the extended position on supracondylar humerus fractures: Does the postoperative long arm splint position matter?

Our study aimed to evaluate and compare the changes in ulnar nerve tension and strain at different elbow positions radiologically and mechanically before and after applying the medial K-wire on the supracondylar humerus fracture cadaver model. We used ten fresh frozen cadaver upper extremity specimens to measure strain and tension on the ulnar nerve in 3 different elbow positions: elbow full extension, elbow flexion-forearm supination, and elbow flexion-forearm pronation. We employed Shear wave elastography (Siemens Acuson S3000 USG, 9L4 linear probe) and a microstrain gauge (Microstrain, Inc.

Coexistence of Pancreatic Neuroendocrine Tumor and Pseudotumor: Two Rare Lesions.

Neuroendocrine tumors and pseudotumors of the pancreas are 2 separate rare lesions. Neuroendocrine tumors originate from neuroendocrine cells, but many different factors have been suggested for the origin of pseudotumors. As the first reports of these 2 distinct entities found in a single patient have been published, our aim is to present the imaging and pathological characteristics of these entities.

Giant Coronary-Pulmonary Artery Fistula Incidentally Detected in a Patient Presenting With Acute Inferior Myocardial Infarction.

Coronary artery fistulas are abnormal connections between the coronary arteries and the heart or other surrounding vascular structures. Although they are usually congenital, they can also occur iatrogenically or due to trauma. They are usually asymptomatic, but they can cause serious and even fatal complications.
