The umbilicus, an essential embryonic organ, connects the foetus to the placenta. Postnatally, its remnants can lead to both benign and malignant lesions. Tumour metastasis to the umbilicus, though rare, poses significant diagnostic and therapeutic challenges due to overlapping clinical and radiological features with benign conditions. In this case series, we present three cases of elderly women with similar presentations of umbilical or infraumbilical lesions, investigated using standard imaging protocols, which subsequently led to different diagnoses and management plans. Case 1 involves a 64-year-old postmenopausal woman, who presented with an enlarging umbilical mass and serous discharge. Imaging revealed a vascularized lesion in the umbilicus and a suspicious adnexal mass, which was confirmed to be a Sister Mary Joseph nodule secondary to high-grade serous carcinoma of the right ovary. Case 2 involves an 80-year-old diabetic woman, who presented with a painful umbilical mass. Imaging revealed an aggressive-looking umbilical lesion, which was confirmed to be liposarcoma. Case 3 involves an 80-year-old woman, who presented with infraumbilical abdominal swelling and fever. Imaging revealed an infected urachal cyst. Histopathology confirmed an abscess associated with infection. An umbilical lesion in an adult, particularly an elderly patient, that does not respond to typical treatment should raise the suspicion of a more sinister diagnosis. Integration of clinical, radiological, and pathological data is crucial for accurate diagnosis and effective management.

To evaluate the clinical efficacy of modified endoscopic mucosal resection (EMR) in the management of early gastrointestinal lesions. Upon endoscopic identification of the lesion, normal saline is injected into the submucosa to establish a fluid cushion, which elevates the lesion's mucosa. Methylene blue may also be applied to improve visualization of the relationship between the submucosa and muscular layer.

Background: This study investigated RANBP2 mutations in children with acute necrotizing encephalopathy (ANE) and conducted a systematic review of the differences in clinical characteristics between with or without RANBP2 mutations.
Methods: Whole-exome sequencing was performed on 19 pediatric ANE patients at Beijing Children's Hospital affiliated to Capital Medical University between 2017 and 2020. A systematic literature review was also conducted on the clinical characteristics and spectrum analysis of RANBP2 mutations.

Purpose: Although both accessory middle cerebral artery (MCA) of distal origin and anterior communicating artery (ACoA) duplication are not rare anatomical variations, their combination is extremely rare and there are only a few reports of such combinations.
Methods: We report a case of distal origin accessory MCA associated with ACoA duplication diagnosed by magnetic resonance angiography (MRA).
Results: A 63-year-old man visited another hospital for screening examinations for cerebrovascular disease.

Analysing samples in their original form is increasingly crucial in analytical chemistry due to the need for efficient and sustainable practices. Analytical chemists face the dual challenge of achieving accuracy while detecting minute analyte quantities in complex matrices, often requiring sample pretreatment. This necessitates the use of advanced techniques with low detection limits, but the emphasis on sensitivity can conflict with efforts to simplify procedures and reduce solvent use.
