Presentation
The present case study reports three cases of histopathologically diagnosed pituicytoma. Clinical presentations, surgical strategies and treatment outcomes are presented and the relevant published literature is discussed. [ncbi.nlm.nih.gov]

- Frontal Headache
Case report: We report the case of a Caucasian male with no significant medical history who develops isolated frontal headache at the age of 48. [endocrine-abstracts.org]
Workup
During the course of his workup, an MRI of the brain was performed, which showed a pituitary/sellar mass. In 1997, the patient had a recurrence of the tumor and underwent surgery, which suggested the diagnosis of pituicytoma. [academic.oup.com]
The lab workup of acromegaly is straightforward. Your screening test is a spot blood insulin-like growth factor I (IGF-I). If this is normal, acromegaly is unlikely. [pathguy.com]
Treatment
Total resection is the treatment of choice, since subtotal removal can often lead to recurrence or progression. [endocrine-abstracts.org]
Tumor resection is the primary treatment option, but remains subtotal due to excessive bleeding in many cases. The search for alternative or additional treatment regimens is necessary. [ncbi.nlm.nih.gov]

Prognosis
The prognosis and role of adjuvant therapy remain unclear for this discrete noninfiltrative glioma. [ncbi.nlm.nih.gov]
This fourteenth volume of the series provides comprehensive, current information on the diagnosis, therapy and prognosis of brain tumors and spinal tumors. [books.google.com]
Treatment and prognosis As the tumors are benign and slow-growing if asymptomatic then expectant management is sufficient. If mass effect is present then resection may be required. [radiopaedia.org]
Etiology
Although three cases of pituicytoma with elevated plasma adrenocorticotropic hormone (ACTH) have been reported previously, the etiological mechanisms remain unknown. [file.scirp.org]
Little is known of the etiology or genetics (J. Neurosurg. 98 : 162, 2003). Grossly, most of these tumors usually filled with little cysts that contain an unsavory, cholesterol-rich fluid ("machine oil"). [pathguy.com]
Epidemiology

However, the epidemiology is not well known because of low incidence of the tumor. The clinical symptoms of pituicytomas are variable according to tumor size and location. [btrt.org]

Prevention
We removed the suprasellar tumor by the transcranial approach to decompress the optic nerves and chiasm to prevent permanent visual loss after angiography and recognition of the unusual pathology. [btrt.org]
POU1F prevents productions of GH, prolactin, and TSH (J. Clin. Endo. Metab. 90 : 4762, 2005). Even ACTH usually is insufficient: J. Clin. Endo. Metab. 89 : 5256, 2004. [pathguy.com]
At present, most patients are treated as having a clinically nonfunctioning adenoma, and the therapeutic goals are restoration of visual deficits, preservation of pituitary function, and prevention of recurrence. [15] Null cell adenomas and oncocytomas [emedicine.medscape.com]
