Sagittal thoracic MRI images demonstrating a T2-6 posterior epidural mass lesion, hypointense in the T1-weighted (a) and hyperintense in the T2-weighted sequences (b), demonstrating significant contrast attenuation (except for a small necrotic area) following intravenous gadolinium application (c). The mass is noticed to compress the spinal cord and cause myelopathy (white arrow). No pathological signal changes are noted in the bony structures and paraspinal area; fat-suppressed T2-weighted (d) and T1-weighted fat-suppressed sequences following intravenous gadolinium injection (e) demonstrating edema and inflammatory changes of the paraspinal area in addition to the extradural mass (black arrows)
