“Pure” Suprasellar Schwannoma Presented with Communicating Hydrocephalus: A Case Report

Abstract

Schwannoma is a benign peripheral nerve sheath tumor originating from Schwann cells. Most intracranial schwannomas arise from vestibular nerve and schwannoma in the suprasellar region is extremely rare. A 64-year-old man presented with walking disturbance and blurred vision for three months. Lateral hemianopsia in the left eye and brachybasia were observed. Magnetic resonance imaging revealed a suprasellar tumor with strong contrast enhancement associated with communicating hydrocephalus. The cerebrospinal fluid tap test improved gait disturbance. Hypothalamic stimulation test revealed hypo-reaction of GH, FSH and LH. After ventriculo-peritoneal shunting, the tumor was totally removed via a bilateral front-basal approach with a clinical diagnosis of craniopharyngioma. No adhesion was observed between the tumor and surrounding structures such as meninges and brain. The histopathological diagnosis was schwannoma. Here we report a case of suprasellar schwannoma associated with communicating hydrocephalus that has not ever been previously reported, with special reference to its pathogenesis.

Ectopic schwannoma of the sellar region in a 1-year-old child: A case report and review of literature

“…According to the reported cases [Table 1], intrasellar schwannomas pick young to elder age groups and are more common in elderly individuals in an average of 49.5 years (range: 19-79 years). [1,[3][4][5][6][7][8][9][11][12][13][14][15][16]19,[21][22][23][24][25]27,29,30,32,33,35] ey have a good prognosis and affect males to females equally (20:19).…”

“…[1][2][3][4][5][6] The histomorphological and immunohistochemical features of SCO and its morphological differentials are summarized in Table 1. [8][9][10][11][12][13] Surgery is the primary mode of treatment. Trans sphenoidal and transcranial approaches had been reported.…”

Schwannoma Presenting As Pituitary Macroadenoma: Case Report

“…It has been reported in about 30 cases have been reported till now in literature. 6,7 Pituitary adenoma, craniopharyngioma, meningioma amongst others are common sellar pathology. Clinical presentation is similar to pituitary adenoma.…”
