A Primary Pigmented Choroid Plexus Papilloma Located Within the Sella Turcica: Case Report and Literature Review.
World Neurosurgery 2017 September
BACKGROUND: Choroid plexus papillomas (CPPs) are rare benign tumors, and the pigmented subtype is observed even more rarely.
CASE DESCRIPTION: We 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.
CONCLUSIONS: This case study provides important clinical information for the evaluation, diagnosis, and treatment of pigmented CPP in the sellar region.
