Meningeal leiomyoma in an adult with AIDS: CT and MRI with pathological correlation.

We describe the imaging features of a meningeal leiomyoma with pathological correlation in an adult with AIDS. On CT the tumour showed a central low-attenuation area and an enhancing peripheral ring. It gave low signal on T1 weighting and on T2-weighted images a central high-signal area was surrounded by a markedly low-signal band, which showed contrast enhancement. As far as we know, this is the first report of this condition in the radiological literature.
