An ACTH-secreting pituitary adenoma within the sphenoid sinus.
A 68-year-old woman developed Cushingoid features three months prior to admission. She was found to have a markedly elevated plasma ACTH-cortisol level. Magnetic resonance imaging (MRI) revealed a mass in the left sphenoidal sinus, which had become enlarged to a point where it could not be removed by transsphenoidal surgery. We decided to proceed with radiation therapy to shrink the tumor. Howe...
متن کاملNeuronavigation used for the transsphenoidal resection of a pituitary adenoma accompanied by a concha sphenoid sinus.
A concha non-pneumatized sphenoid is considered to be a contraindication for the transsphenoidal resection of a pituitary adenoma. Specifically, this anatomical variation makes it difficult to approach the sella turcica. However, in this report, an intra-operative navigational system was used as a guide to access the sella through the sphenoid sinus. This procedure was found to be both reasonab...
متن کاملEctopic Thyroid Masquerading as Pituitary Adenoma
To the Editor: We reported 2 cases of ectopic thyroid gland (ETG) masquerading as pituitary adenoma (PA). The first case was a 15‐year‐old boy with growth, and mental retardation whose height was 121 cm and weight was 44 kg on admission. Bone age development index was 40, while bone age showed 6–10 years old. Magnetic resonance imaging (MRI) revealed pituitary hyperplasia [Figure 1a]. Thyroid u...
متن کاملSphenoidal Ectopic ACTH-secreting Pituitary Adenoma
INTRODUCTION Ectopic pituitary adenoma is defined as adenoma that occurs outside the sella without any continuity with the normal pituitary gland [1]. Since its description for the first time in 1909 by Erdheim in the vomero-sphenoidal region, about 75 cases have been reported in literature [2-12]. Sphenoid sinus followed by the suprasellar region remains the most common site for these adenomas...
متن کاملEndoscopic anatomy of sphenoid sinus for pituitary surgery.
Endoscopic endonasal transsphenoidal approach to the sellar region yields an alternative to classical microsurgical approaches. Endoscopes provide images that differ from microscopic view. This study aimed to highlight surgical landmarks and their anatomical relationships for pituitary surgery through endoscopic perspective. Ten sides of five adult cadaveric heads with red-colored latex injecte...
