Meningiomas are mostly benign brain tumors with minimal malignant cases. Anaplastic meningioma has malignant morphological characteristics and a World Health Organization grade of III. ⋯ This case highlights the potential for low-grade meningiomas to undergo malignant transformation, particularly in the presence of irregular lobulation, peritumoral brain edema, and heterogeneous enhancement on contrast-enhanced scans. Total excision (Simpson grade I) is the preferred treatment option, and long-term imaging follow-up is recommended.

Indwelling ureteral catheter, double J tube, or nephrostomy tube are routine procedures for percutaneous nephrolithotomy (PCNL) in children. There are a few cases in which PCNL has been performed in children without any additional instruments being left in place. ⋯ We believe that total tubeless PCNL without artificial hydronephrosis can be achieved in the preschool population.

Acute stroke requires accurate imaging to ensure appropriate treatment decisions and favorable clinical outcomes. Computed tomography has long been used as an exclusive imaging technique to assess intracerebral hemorrhage, owing to its rapid scanning time and widespread availability. Several recent studies have reported the reliable detection of hyperacute hemorrhage using magnetic resonance imaging (MRI). ⋯ Clinicians in the Department of Neurological Emergency should be familiar with imaging findings of hyperacute hemorrhage on multiple MRI sequences.

Point-of-Care Ultrasound (POCUS) is a quick, useful, noninvasive, and inexpensive diagnostic tool used for the diagnosis of trauma, abdominal pain, dyspnea, and chest pain in the emergency department (ED). However, the diagnostic accuracy of ultrasound in the ED may be different from those reported in previous studies owing to the setting and time constraints in ED. ⋯ The use of ultrasound for the diagnosis of acute appendicitis in the ED showed that ultrasound has high overall sensitivity and specificity for the diagnosis of acute appendicitis. however, high heterogeneity among the included studies was observed.

Triple-negative breast cancer (TNBC) is associated with younger age and worse long-term survival. However, the characteristics and prognosis of different subtypes of breast cancer (BC) in young (<40 years) patients have not yet been elucidated. The present population-based study explored the clinical and pathological characteristics of young TNBC patients and investigated their long-term survival. ⋯ Our research is the first to investigate the relevant characteristics of young TNBC patients in comparison with those of young non-TNBC patients based on the surveillance, epidemiology, and end results database. We found that young TNBC patients have a higher pathological stage and worse long-term survival than young patients with other BC subtypes. These findings have implications in identifying young patients with TNBC for aggressive therapy and further investigations should be performed to explore new multimodal treatments for such patients.
