Background: Neuroendocrine tumors (NETs) of the appendix are typically detected incidentally during appendectomy. Recent studies reported no metachronous metastases among patients with primary tumors <2 cm, regardless of lymph node status or referral for completion hemicolectomy. However, questions persist regarding the possibility of metastases developing decades after surgical resection, particularly because appendiceal NETs are frequently diagnosed in young adults and children.

Rationale: Spontaneous uterine rupture, although rare, is a life-threatening obstetric emergency with a high maternal and fetal mortality rate. It can occur without warning, leading to severe complications, including hemorrhage, shock, and fetal demise. The risk factors contributing to uterine rupture are diverse and include a history of uterine surgery (such as cesarean section), trauma to the uterus, abnormal uterine contractions during labor, and underlying conditions like adenomyosis.

Background: Ruptured intracranial aneurysms lead to significant mortality and morbidity. Recent advancements have suggested staged coiling with subsequent flow diverter stent placement may reduce the risk of hemorrhage with dual antiplatelet therapy (DAPT) or stent thrombosis in the acute inflammatory phase after aneurysm rupture while still appropriately mitigating risk of aneurysmal rehemorrhage.

Materials And Methods: A systematic review and single-arm meta-analysis was conducted.

Paragangliomas originating from blood vessels are exceptionally rare, presenting diagnostic challenges due to their histological resemblance to other vascular neoplasms. We present a case study of a 60-year-old woman with underlying hypertension and dyslipidemia with obesity, initially diagnosed with angiosarcoma based on imaging and histological characteristics viewed via CT-guided biopsy. Intraoperative exploration revealed a lobulated tumor located between the inferior vena cava (IVC) and aorta measuring 7 cm × 8 cm, during which the patient developed transient hemodynamic instabilities.
