Objectives: We previously demonstrated the potential of radiomics for the prediction of severe histological placenta accreta spectrum (PAS) subtypes using T2-weighted MRI. We aim to validate our model using an additional dataset. Secondly, we explore whether the performance is improved using a new approach to develop a new multivariate radiomics model.

Human epidermal growth factor receptor 2 (HER2)-low breast cancer has emerged as a subtype of breast cancer, defined by HER2 1+/2+ in immunohistochemistry (IHC) and absence of ERBB2 gene amplification on fluorescence in situ hybridization (FISH). Recent trials showed marked response of HER2-low breast cancer to novel anti-HER2 antibody-drug-conjugates. Data on characteristics of HER2-low breast cancer subtype is limited.

Fetal supraventricular tachycardia accounts for 60-80% of the fetal tachyarrhythmias with prevalence ranging from 1/1000 to 1/25 000 pregnancies. It may be secondary to fetal anomalies or maternal factors. By reviewing the literature, there is no previous article that reports fetal arrhythmia after maternal vaccination.

We present the case of a 30-year-old lady who underwent a core needle biopsy for a BIRADS 4 lesion of her left breast and was diagnosed as having a cellular fibroadenoma. The final diagnosis after excision returned to be a periductal stromal tumor (PST). An extremely rare entity, the PST is actually classified as a subtype of phyllodes tumor, with specific criteria that are only found upon histological examination of the specimen.

Article Synopsis
  • The study assessed how effective diffusion-weighted imaging (DWI) is when combined with traditional MRI in identifying metastatic axillary lymph nodes in breast cancer patients.
  • Results showed that while MRI interpretations were 87.5% specific and 70.3% sensitive, certain characteristics of lymph nodes, such as shape and size, were significantly different between metastatic and nonmetastatic cases.
  • The findings indicated that conventional MRI features like round shape and larger size of lymph nodes were useful in predicting metastasis, while the apparent diffusion coefficient (ADC) value was not a reliable indicator.

Background: Intracranial hemorrhage due to arteriovenous malformation or intracranial aneurysm is a rare but severe complication of pregnancy with maternal and fetal mortality of 20% and 33% respectively. Whether to deliver the patient first, or to treat the aneurysm first is still controversial, but an emergency cesarean section followed by aneurismal treatment appears to be a widely accepted strategy in pregnant women with cerebral aneurysmal complications.

Case: A 38-year-old patient, G3P2A0, presented at 36 gestational weeks with a diffuse bilateral subarachnoid hemorrhage with fourth ventricle bleeding and hydrocephalus.

Renal failure impairs the endocrine system, especially in women, due to hyperprolactinemia, altering fertility, ovulatory cycles, libido and growth in adolescents. Renal transplantation is considered the best solution to the problems of renal failure and and of dialysis, as evidenced by comparing the rate of hyperprolactinemia (100% in chronic renal failure, 60% in patients on dialysis and 35% in post-transplantation). Kidney transplant is less efficient for restoring perfect function of the hypothalamic-pituitary-gonadal axis due in part to the immunosuppressant regimens prescribed.

Background: Ninety per cent of cases of congenital vaginal agenesis are represented by the Mayer-Rokitansky-Küster-Hauser syndrome, the remaining 10% being represented by the testicular feminization syndrome and vaginal aplasia. Numerous surgical methods for the treatment of vaginal agenesis have been described. Neovagina construction by sigmoid colpoplasty seems to be the best surgical option as regards the anatomical and functional outcome.
