Isodense subdural haemorrhage and adjacent meningioma

Case contributed by Dr Craig Hacking



Patient Data

Age: 50-55 years
Gender: Female

There is a isodense extra axial collection that overlies the left cerebral hemisphere that exerts minimal mass effect with minor adjacent sulcal effacement. No midline shift. No intraparenchymal or intraventricular haemorrhage. The basal cisterns are unremarkable. Bilateral patchy white matter hypo attenuation reflects chronic small vessel ischaemic disease.

Incidental hyperdense extra-axial mass indents the left inferior frontal gyrus, which represents a meningioma.

Hyperostosis frontalis interna. No suspicious osseous lesion.


  1. Subacute left subdural haematoma with no significant mass effect.
  2. Incidental meningioma.
