BackgroundChoroid plexus papillomas (CPPs) are rare benign tumors, and the pigmented subtype is observed even more rarely.Case DescriptionWe present the case of a 43-year-old woman with complaints of headache and progressive left monocular visual deterioration, whose initial plain computed tomography CT scan showed an ovate high-density tumor located within the insellar region. Magnetic resonance imaging revealed a homogeneously contrast-enhancing tumor extending from the sella turcica to the suprasellar cistern. Single-nostril transsphenoidal endoscopic resection followed by subfrontal subtotal resection was performed in this patient. Postoperative histology revealed that the tumor consisted of hyperchromatic tissue with papillary features. Higher-resolution examination of the tissue revealed this tissue was composed of hyperplastic columnar epithelial cells with hyperchromatic cytoplasmic pigment. Subsequent immunohistochemistry identified the lesion as a pigmented choroid plexus papilloma. Here we review the current literature, discuss the origin of the tumor, the differential diagnosis, and the roles of surgery and radiotherapy.ConclusionsThis case study provides important clinical information for the evaluation, diagnosis, and treatment of pigmented CPP in the sellar region.Copyright © 2017 Elsevier Inc.
