A Rare Case of Mature Cystic Teratoma of Spinal Cord

Abstract

Intraspinal teratomas are uncommon tumors that arise from embryonic germ cells and can contain elements from all three germ layers. They are usually located in the dorsal or ventral aspect of the spinal cord, and may be associated with spinal dysraphism or other congenital anomalies. MRI is a valuable tool for the diagnosis and characterization of these tumors, as it can demonstrate their location, extent, and composition. We report a rare case of an intramedullary teratoma in a 54-year-old male who presented with progressive paraparesis and sensory loss. MRI revealed a large, heterogeneous intensity solid cystic mass occupying the spinal cord at L1 to L2 vertebral level with cystic and solid components, fat and calcification. The tumor was surgically removed and confirmed to be a mature teratoma by histopathology. The patient had a good postoperative recovery and no recurrence at 6 months follow-up. This case illustrates the MRI features and surgical management of a rare and challenging spinal tumor.
