Silicone-gel breast implant rupture is difficult to diagnose preoperatively. A variety of radiological methods have been used for diagnosis. This study prospectively compares film-screen mammography, high-resolution sonography, and magnetic resonance imaging in the diagnosis of implant rupture using predetermined diagnostic criteria. Thirteen patients (24 implants) underwent film-screen mammography, sonography, and magnetic resonance imaging to evaluate the integrity of their implants. All patients subsequently underwent surgical removal of the implants. Preoperatively, the integrity of each implant was rated on a three-level classification system on the basis of one modality by a reviewer who was unaware of the results of the other two modalities. The three imaging modalities achieved the following sensitivities and specificities, respectively: mammography, 69% and 82%; sonography, 54% and 64%; MRI, 69% and 55%. Even though each modality addresses some of the limitations of the others, in this group of patients, there was no clearly superior imaging tool.

Rationale: Fetal intestinal volvulus, a rare and severe disorder, poses significant diagnostic challenges prenatally and can lead to intrauterine death or adverse neonatal outcomes if untreated in a timely manner. This study reports a case of fetal intestinal volvulus confirmed postoperatively, providing insights into its clinical manifestations, diagnostic methods, and treatment outcomes, thereby enhancing understanding of this rare condition.

Rationale: Microcephaly, epilepsy, and developmental delay (MCSZ) is a rare neurodevelopmental disorder associated with autosomal recessive inheritance of mutations in the polynucleotide kinase 3'-phosphatase (PNKP) gene. Prompt identification and management are essential, as delayed diagnosis or intervention may result in severe complications or mortality. In this case, prenatal screening in the second trimester detected fetal microcephaly with a gradual decline in head circumference, prompting the decision to terminate the pregnancy.

Ischemic stroke (IS), a cerebrovascular condition, is commonly detected by evaluating carotid intima-media (CIA) stenosis. Symptomatic CIA stenosis carries a high risk (up to 32%) of another ischemic event within 12 weeks, while asymptomatic CIA stenosis has an annual risk ranging from 1% to 2%. Therefore, this study aims to explore the diagnostic value of clinical features and carotid plaque characteristics in both symptomatic and asymptomatic IS.
