Pheochromocytoma, paragangliomas, and pituitary adenoma

Localization of mediastinal paragangliomas (pheochromocytoma).

Three endocrine neoplasms: an unusual combination of pheochromocytoma, pituitary adenoma, and papillary thyroid carcinoma.

BACKGROUND Three endocrine neoplasms-bilateral pheochromocytomas, somatotrophic pituitary adenoma inducing acromegaly, and papillary carcinoma of the thyroid-occurred concurrently in a patient. A genetic mutation was hypothesized. Possible previously described genetic mutations were explored. METHODS Clinical assessments, laboratory data, images of tumors, histopathology, and immunohistochemi...

Retrosellar cyst and pituitary adenoma

A case of a pituitary adenoma associated with hyperprolactinemia and contiguous to a supra and retrosellar cyst is presented. Only three patients with pituitary adenomas accompanied by parasellar cysts have been previously described. It is the first time that this relationship is illustrated by Magnetic Resonance Imaging (MRI). Simultaneous occurrence of arachnoid cysts and adenomas is generall...

Hydrocephalus complicating pituitary adenoma.

Hydrocephalus complicated the clinical course of four patients with pituitary adenoma. In three it was noted late, long after surgical intervention and radiotherapy had been carried out. In one patient, hydrocephalus was part of the presenting syndrome. The differential diagnosis of hypopituitarism and occult hydrocephalus is difficult. The possibility of hydrocephalus complicating a pituitary ...
