Metabolically quiescent paraganglioma in a patient with carcinoma cervix: An unusual presentation

Abstract

Paragangliomas (PGLs) are rare tumours arising from sympathetic and parasympathetic paraganglial neural crest cells. Functional PGLs usually present with manifestations of catecholamine excess such as hypertension, flushing and diaphoresis. Non-functional PGLs are diagnosed incidentally during imaging studies and pose a significant diagnostic challenge. Here, we report the case of 42-year-old female patient with carcinoma cervix who presented with a non-fluorodeoxyglucose-avid PGL. This case report highlights the importance of considering PGL in differential diagnosis and the management of retroperitoneal tumours.
