Vascular Supply of Laryngeal Paragangliomas: Case Report and Systematic Review

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Laryngeal paragangliomas are rare, highly vascularized, neuroendocrine tumors. Although surgical resection of these vascular neoplasms is associated with a known risk of significant hemorrhage, the vascular supply of laryngeal paragangliomas has been poorly characterized. Data Sources MEDLINE Ovid, Embase, Scopus, and Google Scholar.

Cardiac Paraganglioma

JACC: Case Reports, 2021
Paragangliomas are rare tumors of chromaffin cells arising from an extra-adrenal location. Unlike pheochromocytomas, they are seldom functional. We present a case of pericardial paraganglioma incidentally encountered on an echocardiographic study ...

Non‐Functional Paraganglioma of the Urinary Bladder: A Rare Cause of Bladder Tumor

IJU Case Reports, Volume 9, Issue 2, March 2026.
ABSTRACT Introduction Paragangliomas of the urinary bladder (PUBs) are rare neuroendocrine tumors, representing less than 0.06% of all bladder neoplasms. While most are functional and associated with catecholamine excess, approximately 15% are non‐functional, often presenting asymptomatically and discovered incidentally.

Imaging Findings of a Primary Paraganglioma of the Liver: A Case Report

대한영상의학회지, 2016
Primary hepatic paraganglioma is an extremely rare type of tumor originating from extra-adrenal chromaffin cells. We report a case of primary intrahepatic paraganglioma in a 52-year-old man, with pathologic confirmation through right hepatectomy.

Differences in Clinical Presentation Between Pheochromocytomas and Paragangliomas

Clinical Endocrinology, Volume 103, Issue 5, Page 651-658, November 2025.
ABSTRACT Objectives Pheochromocytomas and sympathetic paragangliomas (PPGLs) are similar in most aspects. However, they differ in genetic etiology, hormonal secretion, and associated neoplasms. This study aimed to investigate differences in clinical presentation between PPGLs. Design This study employs a retrospective cohort design. Patients The cohort

Hypersecretory Paraganglioma Presenting as Acute Aortic Dissection

JACC: Case Reports, 2020
Abrupt, transient, and severe hypertension evoked by catecholamine-secreting tumors has the potential to manifest as acute aortic dissection. We report the successful, multidisciplinary management of an insidious, extra-adrenal, functional paraganglioma,

Differential loss of chromosome 11q in familial and sporadic parasympathetic paragangliomas detected by comparative genomic hybridization [PDF]

, 2001
Parasympathetic paragangliomas (PGLs) represent neuroendocrine tumors arising from chief cells in branchiomeric and intravagal paraganglia, which share several histological features with their sympathetic counterpart ...

Case Report—An Unusual Presentation of Cervical Meningioma as a Carotid Body Mass Diagnosed by Fine Needle Aspiration Cytology

Cytopathology, Volume 36, Issue 6, Page 606-609, November 2025.
We describe an unusual case of cervical meningioma presenting as a carotid body tumour. This case emphasises the importance of cytoradiologic correlation in lesions with atypical imaging findings; and the crucial role of fine needle aspiration cytology in accurately diagnosing masses in precarious anatomic sites of the head and neck.

Successful management of unsuspected retroperitoneal paraganglioma via the use of combined epidural and general anesthesia: a case report [PDF]

, 2013
INTRODUCTION: Similar to pheochromocytomas, paragangliomas can secrete catecholamines, although they are usually non-functional and clinical presentation is non-specific.

Gallbladder Cancer Concomitant With Para‐Aortic Paraganglioma: A Case Report

Clinical Case Reports, Volume 13, Issue 10, October 2025.
ABSTRACT Gallbladder cancer often presents a poor prognosis and can cause skip metastasis to the para‐aortic lymph nodes. Accurate diagnosis is essential for appropriate treatment. We present the case of an 86‐year‐old male patient with gallbladder cancer initially suspected to have para‐aortic lymph node metastasis.
