Background: Neurologic complications may be the first symptoms of atrial myxomas. Understanding the imaging features of neurologic complications of atrial myxomas can be helpful for the prompt diagnosis.

Objective: To identify neuroimaging features for patients with neurologic complications attributed to atrial myxoma.

Methods: We retrospectively reviewed the medical records of 103 patients with pathologically confirmed atrial myxoma at Xiangya Hospital from January 2009 to January 2014. The neuroimaging data for patients with neurologic complications were analyzed.

Results: Eight patients with atrial myxomas (7.77%) presented with neurologic manifestations, which constituted the initial symptoms for seven patients (87.5%). Neuroimaging showed five cases of cerebral infarctions and three cases of aneurysms. The main patterns of the infarctions were multiplicity (100.0%) and involvement of the middle cerebral artery territory (80.0%). The aneurysms were fusiform in shape, multiple in number (100.0%) and located in the distal middle cerebral artery (100.0%). More specifically, high-density in the vicinity of the aneurysms was observed on CT for two patients (66.7%), and homogenous enhancement surrounding the aneurysms was detected in the enhanced imaging for two patients (66.7%).

Conclusion: Neurologic complications secondary to atrial myxoma consist of cerebral infarctions and aneurysms, which show certain characteristic features in neuroimaging. Echocardiography should be performed in patients with multiple cerebral infarctions, and multiple aneurysms, especially when aneurysms are distal in location. More importantly, greater attention should be paid to the imaging changes surrounding the aneurysms when myxomatous aneurysms are suspected and these are going to be the relevant features in our article.

Background Objectives: Scrub typhus is an acute febrile zoonotic disease caused by the obligate intracellular gram-negative bacteria Orientia tsutsugamushi. Growing data over the last few years on the Indian subcontinent suggest that it is one of the most widespread but under-reported diseases. The study aimed to document the clinical and paraclinical profile and evaluate complications of scrub typhus in severe and nonsevere pediatric age groups.

Background And Objective: Neurofibromatosis-1 (NF1) dystrophic scoliosis is a challenging disease to manage surgically, with multiplanar curves progressing rapidly and unpredictably. Conservative management with bracing is often unsuccessful, and many patients necessitate instrumented fusion to halt progression of their curves. In rare cases, patients can present with spontaneous vertebral subluxation, significantly complicating the surgical management of this already complex disease process.

Background And Objectives: Oligodendrogliomas are primary brain tumors classified as isocitrate deshydrogenase-mutant and 1p19q codeleted in the 2021 World Health Organization Classification of central nervous system tumors. Surgical resection, radiotherapy, and chemotherapy are well-established management options for these tumors. Few studies have evaluated the efficacy of stereotactic radiosurgery (SRS) for oligodendroglioma.

Background And Objectives: Vertebral artery injury (VAI) because of traumatic subaxial cervical spine injury is a rare but potentially devastating condition as it could lead to stroke. The aim of this study was to examine the incidence, risk factors, outcomes, and radiographic predictors of VAI in patients surgically treated for subaxial cervical spine injuries at a tertiary care trauma center.

Methods: This is a retrospective population-based cohort study, including all patients surgically treated for traumatic subaxial cervical spine injuries at the study center between 2006 and 2018.

Background: Many studies have reported the renal outcomes and metabolic consequences after augmentation cystoplasty (AC), however few studies have discussed changes in renal tubular function. The aim of this study was to determine the prevalence of metabolic disturbances, evaluate renal tubular function and 24-hour urine chemistry to evaluate the association between metabolic alterations and urolithiasis after AC.

Methods: We investigated serum biochemistry, blood gas, and 24-hour urinary metabolic profile of children who underwent AC between January 2000 and December 2020.
