Extradural meningioma in the left fronto-temporo-parietal region.

A case of a 47-year-old male patient who presented with a history of complaints of headache, vertigo and an expanding painful swelling on the left side of the head over the last year is reported. The lump was 15 x 15 cm and protruded 1-3 centimeters. Neurological examination revealed the presence of a mild right hemiparesis with right central facial palsy. Plain skull X-ray film demonstrates a heterogeneous bone thickening in the left fronto-temporo-parietal region with a small osteolytic focus and spotted shadows. Computed tomography scan of the skull showed that a major part of the squamas of the frontal and temporal bones were transformed into spiculoform structures turned outwards and inwards. Thus the bone appeared thickened overall. There were no alterations in the cerebral structures. The tumour was completely removed. It was located extradurally and through the bones extended to the soft tissues under the skin. The histological findings showed a meningioma with hemorrhages and necroses and the presence of lipids containing xanthochromic cells. After a surgical extirpation of the tumour a reduction of the neurological symptomatology and subjective complaints was observed.
