Case report: Paraganglioma masquerading as angiosarcoma: diagnostic-dilemma in vascular tumors.

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.

Bilateral carotid body tumours: a case report from surgeon's perspective.

Carotid body tumour (CBT) is the most common paraganglioma of the head and neck and may compromise neurovascular structures such as carotid vessels, and cranial nerves. Intracranial extension from the mass is possible if left untreated. The main treatment for CBT is surgical resection albeit extremely challenging due to tumour hypervascularity and its relationship to the carotid artery.
