Taken together, the admission diagnoses of pituitary abscess and Rathke's cleft cyst (RCC) were carefully considered and discriminated before operation.
Others include pituitary adenoma, meningioma, lymphoma, central neurocytoma, pineal region tumors such as germinoma and pineocytoma, colloid cyst, Rathke's cleft cyst, arachnoid cyst and metastasis.
This study had one case of Rathke's cleft cyst, which was incidentally detected in patients.
They discuss hypothalamic function and pathophysiology, including vasopressin, oxytocin, and corticotropin-releasing hormone and neuroendocrine regulation, stress and water metabolism, and their role as mediators of emotional and social behaviors; new developments in disorders of the pituitary gland, including active and inactive adenomas, Rathke's cleft cysts, craniopharyngioma, and unusual forms of hypopituitarism; and controversial issues like Nelson syndrome, familial pituitary tumors, and autoimmune hypophysitis, as well as central adrenal insufficiency, hypothyroidism, growth hormone deficiency, the irreversible consequences of pituitary tumors and their treatment on quality of life and neuropsychologic function, and neuroendocrine mechanisms in adaptation to exercise.
Rathke's cleft cysts are congenital cysts that represent remnants of Rathke's pouch, a dorsal invagination of the stomodeal neuroectoderm that ascends from the oral cavity into the sella to form the adenohypophysis.
The tumor appeared to be growing in the vicinity of the pituitary as evidenced by a small portion of Rathke's cleft epithelium.
Adrenal computed tomography (CT) revealed bilateral adrenal hyperplasia and pituitary magnetic resonance imaging (MRI) demonstrated a hypointense lesion, 7 x 4 mm in size, on the right side of the pituitary gland (Figure 1a and Figure 2) and a cystic lession, 4 mm in size, consistent with Rathke's cleft cyst in the central part of the pituitary (Figure 1b).
The differential diagnosis of cystic lesions of the sella includes ACs, craniopharyngioma (CP), Rathke's cleft cysts (RCC), and cystic metastases to the pituitary or sella.
Rathke's cleft cyst was initially diagnosed preoperatively, and the tumor was totally resected by transsphenoidal surgery.
8) Isolated hypogonadotropic hypogonadism is a rare finding and being reported in a patient with Rathke's cleft cyst.
The patient was initially diagnosed with Rathke's cleft cyst (RCC) and refused to undergo the operation.
