Patient Data

A dural-based mass is located posterior to the thoracic cord, markedly compressing it. It is iso-intense to cord tissue on both T1 and T2 weighted images, and demonstrates vivid contrast enhancement. Dural tails are seen extending above and below the lesion. 

Histology

MACROSCOPIC DESCRIPTION: Spinal tumour: A soft cream ovoid fragment 12x10x10mm.

MICROSCOPIC DESCRIPTION:    The sections show a moderately cellular meningioma.  The tumour forms  many whorls with psammoma bodies. The tumour cells have ovoid nuclei  with no nuclear pleomorphism. Mitoses are inconspicuous.  There is no necrosis. No spinal cord parenchyma is seen. There is no atypical or  malignant change.   

FINAL DIAGNOSIS:   Spinal tumour: Meningioma (WHO Grade I).
