“…A number of patients also had vague complaints of memory changes, dizziness and fatigue. Only 1 patient presented with tumor apoplexy (6). Of our cases, only 1 patient presented with diabetes insipidus, which was uncommon.…”

“…Scothorne reported the first case in 1955 (1). Since then, 28 additional cases (not including the present two cases) of this neoplasm have been reported (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14), including one autopsy case (5). It is difficult to identify pituicytomas from other sellar and suprasellar neoplasms, such as granular cell tumors and pilocytic astrocytomas.…”

Pituicytoma: Report of two cases

Abstract. This report describes two cases of pituicytoma. The two patients were female and presented with visual complaints, diabetes insipidus, headaches and menstrual disorders. The imaging characteristic was an intrasellar or suprasellar mass, and one mass originated in the pituitary stalk. The mass showed homogeneous enhancement with contrast administration. A hematoxylin and eosin stain showed a compact structure consisting of elongated, bipolar spindle cells arranged in interlacing fascicles or assuming a storiform pattern. Immunohistochemically, the tumor showed diffuse strong expression of S-100 protein, vimentin and epithelial membrane antigen, and glial fibrillary acidic protein was focally positive. The pituicytoma may have originated in the pituitary stalk and presented with diabetes insipidus, and the differential diagnosis should be compared with the pituitary stalk mass. Bleeding during resection was moderate, and surgery was regarded as the first choice of treatment for pituicytomas.

“…The clinical details were not available in one case. The most common symptoms of pituicytoma were vision and visual field disorders (44 cases, 56.4%), headaches (34 cases, 43.6%), hypopituitarism (17 cases, 21.8%), hyposexuality (16 cases, 20.5%), sexual dysfunction (7 cases, 9.0%), menstrual disorder (7 cases, 9.0%), dizziness (6 cases, 7.7%), diabetes insipidus (3 cases, 3.8%) (10-12), epilepsy (3 cases, 3.8%) (13)(14)(15), gynecomastia (3 cases, 3.8%) (10,16,17) and spontaneous tumor hemorrhage (1 case, 1.3%) (18). There were also sporadic cases that presented with nausea (6), vomiting (9) or edema (9).…”

“…The duration of the symptoms prior to the diagnosis ranged from a few months to several years. One patient had acute symptomatic onset due to spontaneous tumor hemorrhage into the third ventricle (17). There was one case of accidental head trauma in which a diagnosis of pituicytoma was made (20).…”

Abstract. Pituicytoma is a rare tumor of the sellar and suprasellar regions, arising from the pituicytes, which are specialized glial cells in the neurohypophysis and infundibulum. Due to its rarity, ambiguity persists over the diagnosis, management and prognosis of pituicytoma. The current study presents a case series of three patients, each with a histopathological diagnosis of pituicytoma. A summary of the clinical manifestations, radiological characteristics, histopathological features, treatment strategies and prognoses are presented. In addition, 78 cases of pituicytoma, identified in a search of the published literature in Pubmed, are profiled. Pituicytoma typically presents with dysfunction of the optic nerve and pituitary. The radiological characteristics are nonspecific; diagnosis is typically made on the basis of histopathological results. The tumor is slow growing and benign and is amenable to surgical treatment by gross total resection; subsequent tumor recurrence is rare. A definitive assessment of prognosis requires an extended follow-up in a larger cohort.
