Objective: The purpose of this study was to evaluate the characteristics and meaning of the vessel wall irregularities sign, observed on computed tomography angiography of the pulmonary arteries of patients with coronavirus disease 2019 (COVID-19) pneumonia.
Materials And Methods: This retrospective study of the computed tomography pulmonary angiography findings of 65 patients diagnosed with COVID-19 included 27 women and 38 men, with a median age of 52 years (range, 20-86 years). The diagnosis of COVID-19 was established through reverse transcription-polymerase chain reaction for infection with severe acute respiratory syndrome coronavirus 2.
Results: The vessel wall irregularities sign was observed in 50 (76.9%) of the 65 patients with COVID-19. Among those 50 patients, the vascular involvement was predominantly mixed (arterial and venous) in 43 (86%), subsegmental in all 50 (100%), segmental in 13 (26%), bilateral in 46 (92%), affecting 4-5 lobes in 35 (70%), mainly in the right lower lobe in 46 (92%), and mainly in the left lower lobe in 44 (88%).
Conclusion: The vessel wall irregularities is a prevalent sign of vascular involvement in patients with COVID-19.

BACKGROUND Fibrosing mediastinitis (FM) is a rare, fibroproliferative disorder within the mediastinum. It is extremely rare for hematologic malignancies to develop as FM. CASE REPORT A 32-year-old Japanese man with a 1-month history of headache and 2-week history of facial swelling underwent chest computed tomography (CT); a diffuse mass-like lesion was revealed in the anterior mediastinum with severe stenosis of vital mediastinal organs.

Introduction: The dentoskeletal effects of clear aligner treatment (CAT) with Invisalign vs temporary skeletal anchorage device-anchored Sydney intrusion spring (SIS) were compared in consecutively treated growing patients with anterior open bite using cone-beam computed tomography scans.
Methods: Fifteen adolescents treated exclusively with Invisalign, and 14 with SIS (first-phase treatment) were assessed retrospectively. Rigid-wise, voxel-based registration of pretreatment and posttreatment cone-beam computed tomography scans were performed using the anterior cranial base, maxillary plane, and mandibular body as reference regions.

Purpose: This study aims to investigate the indications and therapeutic efficacy of flow-diverting stents (FDSs) in the management of extracranial carotid artery aneurysms (ECAAs) and dissections.
Methods: A retrospective analysis was conducted on 18 patients treated for ECAAs with an FDS between 2010 and 2024. Patient demographics, aneurysm characteristics, procedural details, and clinical and radiologic follow-up outcomes were extracted from medical records.

Background: Cardiac computed tomography imaging with contrast is being used increasingly to image left atrial appendage occlusion (LAAO) devices. Contrast flow across a device, also known as a transfabric leak (TFL), may indicate a lack of complete LAAO-device endothelialization. The data on the rate, predictors, and clinical events associated with TFL are limited.

Background: The short-term and midterm impact of gender differences on transcatheter aortic valve implantation (TAVI) has been studied. However, the impact on long-term clinical outcomes remains unclear. The objective of the study was to investigate the impact of gender differences after TAVI on long-term clinical outcomes and structural valve deterioration (SVD).
