Angiographic findings in recurrent meningioma
KF Lee, SR Lin, WH Whiteley, FY Tsai, NL Thompson Jr and JH Suh
Of 147 patients who underwent radical surgery for intracranial meningioma,
25 (17%) had symptomatic recurrence requiring further surgery. Correlation
between histological and angiographic findings of recurrent meningioma was
poor. Following extirpation of feeding meningeal vessels in convexity
meningiomas, the principal blood supply was usually from the anterior,
middle, and/or posterior cerebral arteries. The angiographic appearance was
that of a "tree-root" or "sunburst" pattern, indicating neoplastic invasion
of the pia mater and/or underlying brain tissue. Polytomography, selective
cerebral angiography, and radionuclide imaging of the brain are often
necessary to detect early recurrent meningiomas. Computed tomography
appears to be an innocuous and accurate method of diagnosing recurrent
tumor, especially when the bone is not involved.
