Relato de caso: Paraganglioma retroperitoneal ocasionando dor abdominal e níveis de pressão arterial dentro da normalidade

Abstract

Paragangliomas are neuroendocrine neoplasms originating in the paraganglia of the sympathetic and parasympathetic nervous system. Diagnosis is challenging when symptoms and imaging features are nonspecific. We present a 34-year-old female patient with abdominal pain and normal systemic blood pressure levels. A hypervascular abdominal mass was visualized in the retroperitoneum through imaging exams, and she underwent ultrasound-guided percutaneous biopsy. The final diagnosis was non-functioning retroperitoneal paraganglioma, established by histopathological and immunohistochemical analysis of the fragments. Our aim is to alert physicians to the possibility of paraganglioma in an atypical clinical setting.
