“…A microscopic transsphenoidal approach is highly recommended, in that it renders good visualization, facilitates complete or near-complete removal of the tumor possible, and can be technically simpler if the mass has already widened and invaded sinus walls without high morbidity. 4 Correct diagnosis is usually established by histopathological and immunohistochemical examination of surgical specimens 15 ; most reported intrasellar schwannomas were initially misdiagnosed as pituitary adenomas or other tumor types before surgery. 1 , 9 , 16 Although none of the previous reported cases underwent second surgeries for remnant or recurrent tumors, adjuvant treatment such as radiotherapy can be considered.…”

In central nervous system, schwannomas, as ubiquitous tumors, mostly originate from sensory nerves like auditory and trigeminal nerves. However, intrasellar schwannomas are extremely rare. They are often misdiagnosed as pituitary adenomas.We report a rare case of schwannoma in the sellar region—a challenging diagnosis guided by clinical presentations, radiological signs, and postoperative pathological test.We represent a 65-year-old woman who had suffered from headaches, hypothyroidism, and visual disturbance. Her MRI revealed an abnormal sellar region mixed-signal mass lesion with suprasellar, left parasellar, and sellar floor invasiveness. We present detailed analysis of the patient's disease course and review relevant literatures. Written informed consent was obtained from the patient for publication of this article. A copy of the written consent is available for review by the editors of MEDICINE. Because this article does not involve any human or animal trials, there is no need to conduct special ethic review and the ethical approval is not necessary.When surgically treated, her specimen revealed a typical histopathology pattern of schwannoma. The patient's symptoms improved a lot after surgery and he continues to be under observation.Despite its rarity, intrasellar schwannoma should be considered in the differential diagnosis of sellar lesions that mimic pituitary adenomas.

Intra-Suprasellar Schwannoma Presumably Originating from the Internal Carotid Artery Wall

et al. 2017

View full text Add to dashboard Cite

Intracranial schwannomas are common but intra-suprasellar schwannomas are extremely rare. We represent the case of a 57-year-old woman with an intra-suprasellar tumor that was presurgically diagnosed as an anterior clinoidal meningioma. Intraoperatively it adhered tightly to the internal carotid artery wall and could not easily be dissected, possibly leading to profuse hemorrhage and sacrifice of the carotid artery with coil embolization. Histopathology demonstrated a schwannoma. We reviewed and summarized the clinical, imaging, and intraoperative findings of previously reported intra-suprasellar schwannomas.
