Familial pheochromocytoma.

Pheochromocytomas and Paragangliomas (PGL) form the group of paraganglial tumours which can occur in any paraganglia from the skull base to the pelvic floor. The terminology is not uniform. While the World Health Organization (WHO) applies pheochromocytoma exclusively to adrenal tumours, many clinicians use the term pheochromocytoma also for extra-adrenal abdominal and thoracic tumours, since b...

Childhood Familial Pheochromocytoma

Childhood familial pheochromocytoma was investigated in four patients by abdominal computed tomographic scan, [ IJmetaiodobenzylguanidine scan, and vena caval catecholamine sampling. Results conflicted with surgical findings. Computed tomographic scan identified all four adrenal tumors but missed two mid line tumors in one patient. [I]metaiodobenzylguanidine scan identified two of three adrenal...

Pheochromocytoma presenting as recurrent hypotension and syncope.

We report a case with pheochromocytoma presenting as recurrent syncope due to hypotension. A 71-year-old man was admitted because of recurrent syncope and paroxysmal hypotension. He was diagnosed as having pheochromocytoma. In spite of a large volume of infusion and insulin therapy, syncope and paroxysmal hypotension continued. We speculated that hypotension was mainly due to vasodilatation cau...

Familial recurrent Bell's palsy.

Bell's palsy is a peripheral facial palsy of sudden onset. The etiology of Bell's palsy is unknown and hereditary components may play a role in familial recurrent Bell's palsy. We report three families in which eight patients had a total of 12 episodes of typical Bell's palsy. The pathophysiology of familial recurrent Bell's palsy is discussed.

Childhood familial pheochromocytoma. Conflicting results of localization techniques.

Childhood familial pheochromocytoma was investigated in four patients by abdominal computed tomographic scan, [131I]metaiodobenzylguanidine scan, and vena caval catecholamine sampling. Results conflicted with surgical findings. Computed tomographic scan identified all four adrenal tumors but missed two midline tumors in one patient. [131I]metaiodobenzylguanidine scan identified two of three adr...
