Giant Cell Tumor of the Temporal Bone and Skull Base

Abstract

Giant cell tumor (GCT) is a benign tumor that originates from undifferentiated mesenchymal cells of the bone marrow. The craniums as well as temporal bone are extremely rare locations for GCTs. Clinical, radiological, and anatomical diagnosis of this locally aggressive disease poses a major challenge in clinical practice. In this article, we present a clinical study for a 35-year-old female who was found to have left-sided temporal bone GCT with extension to middle cranial fossa and temporomandibular joint (TMJ) with its clinical features and management.
