Neurofibromatosis and Schwannoma Cases

An 8‐year‐old, male B oxer was examined for an acute onset of ambulatory paraparesis. Neurologic examination was consistent with a T 3‐ L 3 myelopathy. Myelography revealed an extradural spinal cord compression in the region of the T 10‐ T 13 vertebrae. On magnetic resonance ( MR ) imaging, a well‐defined epidural mass lesion was detected. The mass was mildly hyperintense on T 1‐weighted, hyperintense on T 2‐weighted and STIR images compared to normal spinal cord and enhanced strongly and homogenously. Postmortem examination confirmed a primary epidural hemangiosarcoma. Findings indicated that the MRI characteristics of spinal epidural hemangiosarcoma may mimic other lesions including meningioma and epidural hemorrhages/hematomas of non‐neoplastic etiology.
