“…Neuroembryologically, the origin and pathogenensis of ectopic RCC is a subject of controversy, however, it is not surprising to assume that it is similar to the mechanism for ectopic occurrence of the pituitary adenoma or craniopharyngioma2,5). Ectopic locations include the nasopharynx, the sphenoid sinus, the clivus, and the posterior fossa7,11,15).…”

A Rathke's cleft cyst (RCC) is a benign pituitary cyst derived from the remnant of Rathke's pouch, and usually presents as an intrasellar lesion with varying degrees of suprasellar extension. However, to date, a description of a primary prepontine RCC with no intrasellar component has not been reported. The author describes an exceptional case of a symptomatic RCC located behind the sella turcica in a 41-year-old woman who presented with severe headache. The author also provides an embryological hypothesis of the development of an ectopic RCC, with a special emphasis on radiologic characteristics.

“…This implies that further study of therapeutic technique may be warranted in this patient group. Although invasion of pituitary tumors into the clivus has been described, [9][10][11][12][13][14][15][16][17][18] mostly in the form of case reports, 7,8,19 to our knowledge, this is the first study designed to systematically define the clinical and histologic correlates of clival invasion on CT in a large patient cohort.…”

BACKGROUND AND PURPOSE: Clival invasion, a rare but potentially significant complication of pituitary adenoma, is difficult to detect on MR imaging. Because CT is widely used in adjunct guidance of pituitary surgery and it has recently been suggested that preoperative CT may add useful diagnostic information in addition to pituitary MR imaging, we performed the first large cross-sectional imaging study to define the image attributes, clinical correlates, and prognostic implications of clival invasion on CT for pituitary adenoma surgical guidance.

“…Other extracranial sites include the nasal cavity, mid-nasal ductus, nasopharynx (3,28,29), clivus (30)(31)(32)(33)(34)(35), sphenoid, ethmoid, petrous and temporal bone. The majority of the intracranial extrasellar EPAs are located in the suprasellar region (approximately 33%), usually contiguous with the pituitary stalk (28,36).…”

Introduction. Ectopic sphenoid sinus pituitary adenomas are a rare, benign pituitary tissue neoplasm, occurring separate from and without involvement of the anterior pituitary gland. We present a case of ectopic pituitary adenoma confined to the sphenoid sinus, asociated with an empty sella.Case report. A 52-year-old man was addmitted to our neurosurgical department with persistent headache and nasal obstruction of one year duration. Patient presented no endocrine abnormalities and no visual disturbances. MRI revealed a well-defined mass lesion in the sphenoid sinus, hypointense on T 1 -weighted images, hyperintense on T 2 -weighted images, with moderate heterogeneous gadoliniumenhancement. A primary empty sella was associated. Surgery was performed by transnasal transsphenoidal approach. The tumor was removed in a piecemeal fashion. The bony sellar floor was intraoperatively proven to be intact. The pathologic studies confirmed the diagnosis of ectopic nonfunctional pituitary adenoma of the sphenoid sinus. The postoperative course was uneventful.Conclusions. When encountering a tumor within the sphenoid sinus, an ectopic pituitary adenoma should be suspected.A clinical, imaging and endocrinologic evaluation must be undertaken, aiming to identify the nature of the lesion and to initiate the specific therapy. Surgery remains the only way of obtaining a definite diagnosis and cure.
