Abstract:
The majority of intracranial meningiomas are isodense, well-marginated masses, adjacent to a dural surface. They show intense uniform enhancement following intravenous contrast. Atypical appearances can occur. Hypodense meningiomas have been described due to necrosis, cystic change or lipidisation of the tumour. A meningioma is described which showed two unusual features on computed tomography-a uniformly hypodense mass on an unenhanced scan and only minimal contrast enhancement. Extensive lipidisation of the tumour was demonstrated histologically.
