The widespread use of computed tomography (CT) and magnetic resonance (MR) imaging has increased the preoperative diagnosis of dermoid tumors and detection of their complications. In particular, cases of ruptured dermoid tumors, which may manifest as emergent conditions with variable clinical pictures, have typical CT and MR imaging findings. In this report, we present a case of a spinal dermoid tumor, which ruptured into the syrinx cavity and subarachnoidal space.
