- Abstract
Intracranial neuroblastomas are uncommon malignant tumors that usually arise in the supratentorial parenchymal or paraventricular location. A primary neuroblastoma arising in the sella turcica is extremely rare. We report a case of a 76-year-old man who presented with progressive bitemporal hemianopsia. His pituitary hormone levels were within the normal range, except for slightly increased prolactin. Pituitary magnetic resonance imaging revealed a solitary sellar mass with supra- and parasellar extension that mimicked a non-functioning pituitary adenoma or meningioma. The tumor was excised by transsphenoidal resection. Histopathologic analysis revealed small cells surrounded by a dense fibrillary stroma as well as strong expression of neural markers. Hence, the patient was diagnosed with sellar neuroblastoma. Prolactin levels normalized in the immediate postoperative period, although visual disturbances persisted. Herein, we describe the clinical manifestations, MRI characteristics, and histopathologic findings of this case.
