Quality of Life After Surgical Treatment of Head and Neck Paragangliomas

Head &Neck, Volume 48, Issue 4, Page 941-949, April 2026.
ABSTRACT Background Head and neck paragangliomas (HNPGLs) are rare neuroendocrine tumors and often arise in the head and neck. Due to their localization, the tumor and its surgical treatment pose a risk for cranial nerve impairments. Few studies have focused on the health‐related quality of life (HRQOL) in patients with HNPGLs and their relation to ...

Coexistence of pheochromocytoma/praganglioma and renal artery stenosis

Indian Journal of Endocrinology and Metabolism, 2012
Renal artery stenosis (RAS) often coexists with pheochromocytoma (Pheo)/paraganglioma (PGL) and often alters the management of patients with Pheo/PGL. We have studied the prevalence of RAS in our Pheo/PGL patients.

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

IJU Case Reports, Volume 9, Issue 2, March 2026.
